How to install an alarm on a scooter - theory, practice, recommendations

Connecting an alarm system to a scooter is sometimes more difficult than installing a security system in a car. The scooter alarm is connected according to one of two standard schemes, and the choice of scheme depends on the type of ignition switch. It would seem that there is nothing complicated here, but the electrical wiring of scooters may have “nuances” that are usually not taken into account during installation. It is impossible to list these nuances, but you can give examples of connection. This is what is done in the text, as well as in the video, which is given at the end.

Features of installing an alarm on a motto

Let's look at the process of installing an alarm system on a motto: the practical part is installing an alarm system - this is the most effective way to resist robbery.
However, if a couple of years ago, in rare cases, expensive parts were effectively sold in motorcycle parts stores, today Chinese versions of alarms have proven to be in demand. Of course, no alarm system can provide a 100% guarantee, but the chances for scooters will increase significantly. Installing an alarm system on a moto is not such a difficult process.

It is important to correctly identify the option, and it will be very easy to find the necessary model by visiting a motorcycle parts store

For a moto, you can choose an alarm system from Chinese manufacturers who are focused on the global market.

Now let’s move on to consider the process of installing an alarm on a motorcycle:

1. First, we prepare the place for installation of the alarm system on the motto and provide the wiring.

For these purposes, we remove the plastic from the front, under which there are all the necessary contacts along with the connectors.

The remoteness of the battery in this option is not so important, so you don’t even need to look at it. We fasten the plastic with bolts - just unscrew them and it can be dismantled

In some cases, depending on the motorcycle model, the mount may be different. In this case, it is recommended to read the manual.

In terms of technical characteristics, the installation of an alarm system on both a Japanese-made motorcycle and a Chinese-made motorcycle is almost identical. Therefore, this article does not have any connection to specific models of motor vehicles.

Any of the alarm system kits with instructions that detail the areas in the wiring where it needs to be connected. First, we disconnect the ignition switch chip, since no one can be immune from errors, and when igniting it can ruin your life. Then you need to find the main motorcycle wiring, which is designed as a harness and is located mainly in a polyvinyl chloride pipe. In rare cases, but the main wiring is simply wrapped with insulating tape.

We get to each wiring and select blue, orange and yellow-red. Then we remove the insulation and expose the wiring. You can do it another way and, without damaging the insulating tape, connect the alarm system directly to the chip.

Now you can return to the ignition switch and you need to expose the area of ​​the wire at a distance of approximately 5 centimeters from the chip. You can consider the preliminary work completed.

1. We carry out wiring of the alarm system

First you will need to find an area where you can install the central unit. It is recommended to place it under the front plastic if you glue it to the inner area using the special tape that is included in the kit.

For a more durable fastening, we carefully wipe the plastic and then degrease it. When choosing a location, you immediately need to find out the length of the wiring, which is recommended to be cut off rather than hiding the entire mass under plastic. One tourniquet, which is recommended to be left long, is black. And for all others, after determining the length, it is recommended to cut it.

You should definitely leave a couple of centimeters for laying, and expose the ends of any wire by 2 centimeters.

1. Connecting the alarm system

The red wire must be connected to the red ignition switch wire by winding one end to the other. We connect the orange wire to the black one in the same way. Then we connect back the ignition switch and alarm system.

A little about the Chinese alarm kit

According to statistics, scooters and mopeds are stolen much less often if they are equipped with an alarm. However, it should be clear that you cannot be 100% sure that equipment cannot be stolen with an alarm system. But still, if your scooter or moped is located in an unguarded parking space or in the open air, then most likely an alarm will not hurt in such cases. Some find a way out and use a special lock on the disc brake, while others use a simple chain with a lock.

to install alarm systems on scooters and mopeds, both Japanese and Chinese, but when choosing, you need to be careful to understand which option is right for you. Will a particular option be suitable for your transport? Today, many alarm systems are sold in online stores and prices are more affordable than market ones. These are mainly kits made in China, which are intended for the installation of motorcycles, scooters and mopeds.

Often the kit contains standard parts - a central unit, siren, key fobs, wiring harness and contact block, and an instruction manual should also be an integral part.

Below is the alarm diagram for Chinese scooters:

Preparing a place for a scooter alarm

To properly install the alarm on your scooter, you need to dismantle the front plastic in order to get to the connectors and contacts we need. How close or far away the battery is installed does not matter. Well, the plastic is removed by unscrewing the bolts and screws that secure it to the central plastic (it all depends on your model).

There is practically no difference in installing alarms on Chinese-made scooters and Honda scooters. Today we will delve into the installation process specifically for these units. If the kit contains instructions, then you need to mark in it the places in the wiring where the wiring of your alarm will be connected. The first thing you need to do is disconnect the chip from the ignition switch, thereby securing the installation process. After this, you need to find the main wiring harness in the scooter; it is often located in a casing (tube) or isolated in a special tape. In a more suitable place in the wiring harness, you need to remove the insulation in order to have access to all wires without exception. You will need orange, blue, and yellow/red wires, among others. Each of these wires must be stripped of up to 7 mm of insulation and the wiring must be carefully exposed without cutting the wire. In another method, damage to the insulation is not required and here it is possible to connect the alarm wiring to the contacts of the chip. You have the right to choose a more suitable option in your case. For beginner scooter riders, it will be easier to make a simple connection to the wiring.

The next step is the ignition switch. Once the chip is no longer connected to the lock, you can safely do the work without fear that the slightest mistake will cause a short circuit. Having marked a distance of approximately 5 mm from the chip on the red wire, you need to expose its section to 7 mm and do the same on the black wire. The black and white wire goes to the ignition switch; it needs to be cut and the edges cleaned. At this point, the work with all the preparation of the scooter wiring is completed, the next stage is the alarm harness.

Installing an alarm system on a scooter with your own hands competently and effectively

Choosing a suitable alarm

Modern security systems, even for small-sized equipment, allow you to use such practical bonuses as a remote control, starting the engine from a distance and some other advantages.

Security systems for mopeds and scooters are almost as diverse as those for cars. Installing an alarm on a scooter traditionally begins with selecting a suitable model. You can choose a security guard based on different criteria:

• manufacturer;
• price;
• degree of protection;
• set of functions.

Retail chains offer security systems from the most primitive and inexpensive made in China to expensive ones that have decent functionality and are also protected from outside interference.

In order not to make a mistake in your choice, evaluate your financial capabilities and recommendations of manufacturers, and also communicate on specialized forums. The best criterion for selection is reviews from owners who have been using alarms for some time. Advice from sellers and service center specialists will also not be superfluous.

When purchasing, you must check the completeness. The average alarm kit consists of:

• central block;
• sound siren;
• vibration sensor (set of sensors);
• key fobs for remote control;
• set of connecting wires with terminal blocks.

Particular attention should be paid to the installation instructions and wiring diagram, because... in their absence, connecting an alarm to a scooter will be quite problematic

Although the principle of operation and the procedure for installing the system into the design of a moped of different models are not fundamentally different, it is better to use the factory instructions and manufacturer’s recommendations.

How to install an alarm on a scooter - step-by-step instructions

Step No. 1: choosing an installation location.

For scooters with a classic layout, the most suitable place for mounting a central unit with a sensor and speaker is a niche under the front plastic covering. Firstly, there is enough free space here. The installed equipment will not interfere with controls and other components. Secondly, this is where the main wiring harness runs, which you need to connect to. Another installation option is in a niche under the seat. It will be more difficult for a burglar to get to this place, but to connect you will have to increase the number of wires.

Step No. 2: installing an alarm on the moped.

Manufacturers of security devices always offer their own method of mounting the unit and sensors. As a rule, double-sided adhesive elements are used for fastening. An option is available using clamps and brackets. The method of fastening depends on the specific alarm model.

Step #3: connection.

How to install an alarm on a scooter without making a mistake in the wiring order?

To ensure the operation of the security system, two prerequisites are required:

• continuous supply of power to the central unit from the battery;
• correct connection to the ignition system.

Before starting work, to avoid short circuits, the ignition is turned off and the battery is disconnected.

• Take the connection diagram and strictly observe the color of the wires;
• To connect the alarm wiring to the moped's electrical network in the places indicated in the diagram, expose the insulation and connect the ends of the alarm connector wires;
• After checking the correct connection, the connection points are soldered and well insulated.

The most important advice for installing security guards

In solving the problem of how to install an alarm on a moped, owners forget about the biggest drawback of these vehicles. Many models, especially Japanese scooters, allow you to get to the battery without much difficulty. This allows the thief to quickly turn off the power and de-energize the alarm.

Experts strongly recommend taking measures to protect the battery. To do this, a protective metal box is made, and the cables are laid in such a way that they cannot be cut through with a plumbing tool.

How to connect an alarm to a scooter

How to connect an alarm to a scooter. Universal circuit for standard signaling

All scooter alarms that are currently on sale and are cheap or budget, have the same type of connection and there is nothing tricky about it. Alarms can be sorted among themselves only by the set of functions and the type of siren - built-in or remote. (Alarms with feedback, additional motion and volume sensors are not considered here.)

There are very simple alarms with only two functions: arming and disarming. Everything is very simple there. There are only two wires that connect to the battery.

And also there are a couple more functions from inexpensive budget ones: start from the key fob, turn off from the key fob, and when the alarm goes off, turn on additional lighting (turn signals). With these functions, questions usually arise about what to connect where. All these alarms have the same set of wires and the same colors, so using the diagram in the picture you can easily figure out what to connect and where.

Red is a plus, we screw it onto the red wire going to the ignition switch from the battery; Black is a minus, we screw it to the frame, to ground; Blue is for the starter (provided that the engine will be started from the alarm button); Orange is so that the alarm goes off when the ignition is turned on, and it also carries a plus to turn on the ignition when starting from the key fob, screw it to the black wire of the ignition switch; You also need to cut the black wire with a white stripe coming from the ignition switch. Pink - screw it to the wire (black with a white stripe) to the part that extends from the ignition switch; Gray - screw it to another part of this wire; Yellow (double) - two double wires, screw one to light blue, the other to orange (this is the exit for turns).

If (suddenly) your wire colors are different, then you will have to be smart and connect by analogy or by elimination.

Car alarm will not work

A specialized alarm system for a motorcycle will have several advantages over a car alarm:

This last benefit is controversial. Many, on the contrary, like that you can connect a whole set of different sensors to a car alarm.

The main connector connected to car circuits contains 18 wires or more. Add to this the “CZ” connector and the power wire terminal block, and you get 30-35 contacts. Isn't it too much for motorcycle equipment?

Alarms on motorcycles, unlike cars, cannot trigger the starter. Therefore, they do not need 4-5 “extra” contacts connected to the ignition switch. However, you still have to run one wire to the lock terminal block. In the connector it is colored yellow or orange:

Installing a motorcycle alarm begins with connecting the power, and the cord is connected in the second step.

GPS beacon - alarm for scooter? Not only!

When satellite tracking devices emerged, it was unlikely that they would ever be used for scooters. It was not a cheap pleasure - that’s why the scope of application was limited mainly to the special services. Today, a beacon is purchased as an alarm for a scooter, for car safety, and for many other purposes. In this list:

Child safety. Doesn’t answer calls, stayed late after school, was late for training... While parents figure out what’s what and calm down, gray hair may noticeably increase. The fears of adults are not unfounded: every year about 15,000 children disappear in Russia! Alas, 10% of this number are gradually moving onto the list of missing persons. So the question of whether a child needs a beacon is rhetorical

Explain to your child the importance of such a measure, tell them how to use the panic button - and not a single force majeure will go unnoticed. Monitoring the work of a personal driver. Being late for an important meeting is explained by traffic jams, the use of the car for personal purposes is not verbally confirmed, although witnesses saw it outside the city... Sound familiar? What a regular scooter alarm can never do can be easily solved with the help of a beacon

Just hide it in a secluded place of the vehicle - and your personal “agent” will regularly transmit the most reliable information about the location of the car. Monitoring the movement of valuable cargo. For managers of companies involved in the transportation of goods for various purposes, the problem of their safety and the safety of drivers is especially acute. Truckers often become victims of gangs who not only take possession of the cargo, but also injure the drivers. A GPS beacon, of course, will not scare off criminals, but it is unlikely that they will carry out their plan to the end. Unforeseen stops, deviations from the route - all this will be reflected in messages from the lighthouse. Control over the movement of animals. We went out for a walk and before we knew it, our pet was gone. If this is an isolated case (although it may be the first and the last), then the issue of purchasing a “bug” can be postponed until later. But when this happens regularly, a “amulet” for the animal is simply necessary. Recently, GPS beacons have been purchased by farmers and hippodrome owners, which is understandable. Having expensive breeding cattle or exclusive horses, it is very important to be confident in their safety.

Good afternoon, sorry if this is off topic, but I couldn’t find anything suitable for what topic to write. The question is today I suddenly braked and found that the speedometer stopped working, what could be the reason? Is it also possible to install xenon on a scooter? Scooter racer taurus

1alexiss1, regarding the speedometer: unscrew the drive cable from the speedometer itself and spin the front wheel, the inner cable should rotate. If there is no rotation, then something is wrong with the drive, you need to remove the front wheel and see what's what. If the cable rotates, then the problem is in the speedometer. Regarding xenon: xenon can be installed on any scooter, even KAMAZ, it doesn’t matter. The main thing is to carefully study the parameters of a particular ignition unit: what current it consumes, whether it has dust and moisture protection, the vibration resistance of a particular unit must also be taken into account, that is, see whether a specific model of the unit will suit your scooter or not. Like this.

Actually, regarding xenon, I’m now waiting for the Chinese to receive xenon at their warehouse, and I want to create an article about installing xenon on a scooter, since the owners of this equipment are so interested. By the way, I will focus on installing xenon without any modifications or alterations to the generator .. Of course, there are articles on this topic on the Internet, but there we are talking about removing and altering the generator, and on top of all this you still need to spend a X amount of money to purchase shunt voltage regulator. A beginner, I think, will not be able to do such meticulous work.

Evgeniy, the article on installing xenon on a scooter will undoubtedly be very useful and interesting for readers. So we'll be looking forward to it. Regarding the alteration of the generator: if possible, please share the links, I would like to get acquainted.

Installing an alarm system on a scooter with your own hands

An alarm is one of the most effective ways to scare away a thief who is trying to steal your scooter, moped or parts thereof.

But even despite this precaution, scooters and mopeds are subject to theft quite often. Previously, very little had been heard of alarm systems on scooters, and even fewer had used them.

Most likely this was due to the high cost of the kit, if we compare the total cost of motor vehicles. In other words, previously it was completely pointless to install an alarm system on your device, because it could cost the owner almost half the cost of his vehicle.

It is for this reason that many Japanese used scooters and mopeds do not have alarms, like European ones in particular. Today on the market you can buy a budget, but fairly well-made alarm system for motor vehicles - motorcycles, scooters, mopeds. These inexpensive alarm devices can be afforded by almost any segment of the population.

Increased power and speed

The speed of a vehicle is one of the most important factors for many people. Scooter tuning to increase power is carried out quite often, so this type of work is the most common. In order to increase the maximum speed of the scooter, it is necessary to replace the stock gearbox. In this case, standard and factory parts are replaced with sports parts.

It is worth noting that the sports type gearbox does not have any special characteristics. It consists of a pair of standard gears with a different number of teeth.

How is a beacon different from an alarm on a scooter?

Anti-theft is an unusual thing, but it enjoys a certain reputation among scooterists. At the same time, it acts more like a “talisman” than as a remedy against theft. Indeed, an alarm installed on a scooter will not be able to detain a thief or neutralize hacking devices. And the worst thing is that you may never see your scooter again.

In this regard, the lighthouse is much more versatile. Its advantages over the alarm system include:

• Compact and lightweight, because the device’s appearance is not much different from a standard bank card
• Reliability and reliability. It is thanks to this combination that a once fully charged device does not need to be recharged for 9 months
• Availability and reasonable price. You spend one time to purchase the device, there are no subscription fees
• Installing a beacon, unlike an alarm on a scooter, does not require any special skills - you just need to know how to use a phone
• Possibility of personal customization provided by the manufacturer

Alarm with and without blocking

Any alarm system on a motorcycle can be connected so that it does not block the engine. The main unit is equipped with a relay that is activated in the “Security” mode. But the contacts of this relay can be left free, and the three wires coming from the connector are in this case intertwined with each other and insulated. It is not necessary to connect the low-current cord that controls the additional relay. What actually needs to be done is discussed next.

Power, ignition and turn signals

Remember the rule: installing an alarm on a motorcycle begins with disconnecting the battery. Then, two wires coming out of the signaling terminal block are pulled to the battery terminals.

We are talking about the “black” and “red” wire. It is recommended to include a pre-flask (7-10 A) in the gap of the latter.

If everything is in order with the power supply, proceed to connecting the turn signals. In the Starline V62 circuit, one wire goes to them (green-black). So, we do this: we find the turn signal terminal block, and solder one cord to each of the “positive” contacts.

Both additional cords are then pulled to the signaling, where two diodes connected by anodes are installed:

Observe the polarity of these diodes. The current must flow from the signaling module to the lamps.

You can purchase Chinese 1N5408 diodes that can withstand a current of “3 Amps”. If the main connector is equipped with two wires (not as in the example), there is no need to buy and install diodes.

It remains to consider the last stage. Alarms on motorcycles need to "know" whether the ignition is currently on. Therefore, find the conductor on which the “plus” appears after turning the key. In a lock module this is usually a “brown” or “red/blue” cable.

Nuances concerning both schemes

If you connect the security system as discussed above, you can get a workable option, perhaps without remote start. In general, an alarm system on a scooter can be installed in different ways. For example, if you don't need engine lock, just don't cut the wire and connect the "gray" and "pink" cords. You don’t have to connect the siren or the scooter’s turn signals (at the owner’s choice). Further, all the schemes that have been considered will only become more complicated.

We will equip the motor with remote start

The “blue” wire coming from the signaling connector can supply voltage to the relay that turns on the starter. Let's figure out what to connect it to.

There may be several wires coming from the “2” button module, if it is present at all. One of them is connected to a standard relay, and when pressed, the following may appear:

• + 12 Volt. Then, connect the cord itself to the “blue” signal wire (T-shaped connection);
• "Mass" potential. If you need autostart, you will have to buy a relay, the normally open contacts of which are connected between ground and the found cord.

When installing an additional relay, turn on the winding between the “blue” wire and ground. In this case, the signaling electronics must be protected with a diode.

Additional relay wiring diagram

“Chapter 1” looked at how to install an alarm on a scooter with a 4-pin and 2-pin ignition. In the second case, for example, remote start is easier to implement:

Autostart, two-pin ignition

The numbers here indicate the relay connection points:

1. Contact 30;
2. Contact 87;
3. Pin 85 (diode cathode);
4. Pin 86 (diode anode).

As you can see, no new connection points will be added. The only thing is that you have to stretch the cord from ground to pin 86.

The last paragraph does not apply to any equipment produced in China. Simply, Nexus, Racer, Tachilla and many other scooters use a 4-pin ignition.

Standard connection and circuit selection

Let’s say this is the first time an alarm system will be installed on a moped or scooter. Find out right away how many wires go to the ignition switch - 2 or 4. If there are more than 3 contacts in the terminal block, then the second option is probably used. This is 100% true for Chinese scooters, including Racer Dragon, etc. There usually only 4-pin ignition is used.

Lock with 4 contacts

Signatures here indicate the signaling wiring.

The figure lists the wires and contacts:

• Blue (blue). The wire is used for remote starting. “12 Volts” appears on it when you need to close the starter relay. You don’t have to connect it (isolate it).
• Red and Black (red and black). Signal power supply. It is highly recommended to install a 5-7 A pre-flask.
• Orange (orange). Here the signaling system “observes” the voltage value: there is “+12 Volts” - the ignition is on. Ring out the appropriate cord in the terminal block.
• Pink and Gray (pink and gray). The cables are included in the break of the cord going to the switch (its insulation can be white-black, etc.). This cord receives ground potential when the engine is stopped.

A common mistake is the following. The “gray” wire is connected to the lock terminal, while the “pink” wire goes to the switch. If you do this, nothing will burn, but the system will work with errors.

Now, let's look at the second version of the scheme:

Lock with 2 contacts

As you can see, the same alarm system for a scooter can be used, but it must be connected differently. The point is to correctly determine the type of ignition. The starter wire, by the way, in the second option can be broken “to the button”.

There may be a power cord in the terminal block that does not have a certain potential when the ignition is turned off. This cord, usually “light green”, is not at all the same cable that is cut according to “Scheme 1”.

Trying to block the crankshaft sensor

The alarm system on a motorcycle must be installed correctly: it must be possible to dismantle it. It is not recommended to cut the ignition wire to enable blocking. But if blocking is still needed, try to “mute” the signal from the rotation sensor. The wire through which the pulses travel can be connected to ground through a resistor.

Connect a resistor when you are absolutely sure that such blocking does not damage the sensor itself.

Be aware of the following. By installing a low value resistor, the sensor can be “burned out” in a second. And using too high a value (more than 500 Ohms) is ineffective.

The blocking loop might look like this. The resistor is connected to the sensor wire, its other side is connected to the “blue-white” signal cable, and its “blue” cord is connected to ground. The resistor value is selected from the range:

It looks like installing a motorcycle alarm can be done if the required parameters are already known. You need to know the type of sensor, the value of the “blocking” resistance, etc.

In some models of equipment, it will not be possible to block the sensor using the considered method. Simply, there is not always a resistance rating that meets all the criteria at once.
