Elements and wiring diagram of Izh Planet 5, how to detect a malfunction

While easily fixing mechanical failures, motorcyclists experience difficulties if the electrics fail. It’s completely in vain, the wiring diagram of the planet Izh 5 is not complicated, it’s easy to figure out.

There is no need to have special stands and equipment for repairs. A minimum knowledge of electrical engineering and a simple avometer (tester) is enough; even often you can get by with just a test lamp.

We will tell you in more detail about the main electrical wiring components and possible malfunctions. The Izh Planet wiring diagram makes it easy to find a broken wire or damaged insulation (for example, a bad contact always gets hot).

But pay special attention to the fact that the electrical circuit is designed not only for 12 volts, there is also a high-voltage cable (connecting the coil and the spark plug), which cannot be checked with a regular ohmmeter.

In this case, we look to see if there is a spark at the coil output and at the output at the spark plug contact. Let's take a closer look at the main wiring components of the Izh Planet.

Generator

The heart is the generator (sometimes called a magneto, but they were never used on Izh Planet). Three windings produce alternating current. For excitation, an additional coil is used instead of a permanent magnet. Therefore, it is impossible to jump start a motorcycle with a completely dead or missing battery.

A diode bridge for current rectification and a voltage regulator assembled in one unit are mounted on the Izh Planet 5 generator (they are not even highlighted in the Izh Planet wiring diagram manuals).

Possible breakdowns in this unit:

1. Breakdown or breakage of coils. It is checked by measuring their resistance of current-carrying conductors and insulation. If the generator is damaged, it will become noticeably hot.
2. Failure of the diode bridge - the output voltage will differ significantly from the nominal level or be absent.
3. Failure of the voltage regulator. Although the electrical circuit includes short circuit protection, it happens that the automation does not work and most often the output transistor burns out.

Design and reliability

IZH Planet 2, as evidenced by the number in the model name, became the second motorcycle in the Izhevsk Planet series.
It differs from the “ancestor” of the family in greater comfort and power of the power unit, as well as an updated, more modern (for that period of time) design.

Thus, Planet 2 received a signature paint job, a muffler and wheel rims covered with decorative chrome, a polished crankcase cover, as well as brake covers and a carburetor casing with a layer of hammer enamel.

The motorcycle seat has become wider and more comfortable. Its finishing is made of colored textinite.

The second generation model is designed in such a way that its repair does not require special or specific tools, conditions or equipment.

The mechanics are quite simple and straightforward, and spare parts are produced in abundance.

IZh Planet 2 owes its excellent cross-country characteristics to good traction at low speeds, high suspension and competent gearbox design.

Among other things, the owners of the bike unanimously declare the highest reliability of the engine and its amazing durability. This is confirmed by the manufacturer, who provided a warranty for a mileage of 15 thousand kilometers or a year and a half of operation.

Battery

The battery in the motorcycle is low-power. The motorcycle does not have a starter, so its task is only to supply voltage to the ignition system and the generator excitation winding during starting. Thanks to the battery, designed for 12 volts, a stable start of the fifth Planet is ensured; up to the third model, the wiring was 6 volt, and the ignition was not always clear.

Possible battery malfunctions:

1. Mechanical damage - housing, plates, leakage of electrolyte.
2. Loss of electrolyte density is determined by measurements using a hydrometer.
3. The short circuit of the plates in the banks is detected by measuring the resistance.
4. It is possible that the connection is not correct, minus not on the body (frame) of the motorcycle - all the electronics will not work.

How to improve the standard electrical system?

As we have already said, standard wiring does not cause any particular complaints due to its solidity, ability to withstand oxides and rust at the joints, without losing functionality. That is why complete replacement of wiring is a questionable procedure, but upgrading individual parts makes sense. By individual parts, we mean such functional elements as head lights, indicators, turn and stop lamps, ignition system, generator. Let's talk about each of the elements separately.

Ignition system

The ignition chopper is used to ignite a spark at a certain point in the piston stroke. In early modifications of the electrical wiring of Izh Planet 5, contact was mounted, later electronic.

The main malfunctions of this unit:

1. Burning of breaker contacts is determined visually.
2. Failure of a sensor or switch elements - the easiest way to detect it is to use the method of installing a known-good unit. The lubrication system sensor valve is also checked using the same method.
3. An incorrectly set ignition timing is visible from the fuzzy operation of the engine. It can be eliminated by adjustment using special probes.

The ignition coil increases the voltage to several kilovolts so that the discharge can ignite a spark at the spark plug electrodes. The secondary winding is made of a fairly thin wire; most often it burns out. Although a breakdown between the turns or onto the housing is also possible. The same troubles can (but less often) happen to the primary circuit. Everything is revealed using resistance measurements.

Maintenance

The owner can independently perform some maintenance procedures:

• check the motorcycle generator if the battery loses charge;
• set the gap between the breaker contacts;
• adjust the quality of the sound signal.

The need to inspect and adjust the wiring arises if:

• the motorcycle moves in the rain for a long time, as this causes oxidation of the contacts;
• a motorcyclist rides in an area with a lot of vegetation that damages wiring;
• The driver rides in snow in winter, which can stick to electrical wiring parts and damage them.

Self-check of the Planet 5 motorcycle generator in case of loss of charge

The cause of loss of charge in the IZH Planet 5 battery is most often a breakdown of the generator.

To check it yourself you need:

• multimeter device;
• straight screwdriver.

Step-by-step instruction

The following steps must be followed:

1. Disconnect the wires from the battery and remove the generator cover.
2. Disconnect the top 5 wires from the generator, first unscrewing their fastenings. In order not to mix up the wires during assembly, it is worth marking them.
3. Measure the winding resistance using a multimeter in ohmmeter mode. To do this, you need to touch the body with one probe, and the other should be connected in turn to the 3 wires of the winding. There should be no short circuits, as indicated by the inscription on the multimeter screen.
4. Test the resistance between the stator contacts: you need to touch them one by one with the multimeter probes. The value on the screen should be 8 ohms.

The presence of a short circuit in the 3rd stage or a discrepancy in the indicators in the 4th will indicate problems with the generator.

How to correctly set the gap between the contacts of the breaker?

In order to set the gap between the breaker contacts, you will need:

• straight screwdriver;
• wrench 10;
• candle key;
• probe 0.4 mm thick (+/– 0.05 mm).

Next, you need to follow the steps sequentially:

1. Place the motorcycle on a stand and place the gearbox in neutral.
2. Remove the right crankcase cover and unscrew the spark plug.
3. Using a 10mm wrench, grab the generator rotor mounting bolt and turn the crankshaft to a position where the contacts are as far apart as possible.
4. Loosen the screw securing the contact.
5. Place the probe between the contacts and adjust the tightening of the eccentric screw until the probe passes the contacts with little resistance.
6. Tighten the contact fixing screw.

Troubleshooting the audio signal and improving signal quality

Poor sound signal quality is mainly caused by improper adjustment.

The following tools will be needed for setup:

• wrench 7;
• a simple screwdriver.

Step-by-step instruction

To adjust, do the following:

1. Loosen the locknut with a wrench.
2. Turn on the ignition.
3. Press the button to turn on the sound signal.
4. Adjust the sound by rotating the adjusting screw.
5. When the desired result is achieved, tighten the locknut.

Retro style

Nowadays the fashion for old and vintage cars and motorcycles is actively developing. Models from 30 to 50 years ago are kept in barns and distant villages to be restored to their original form. The idea of ​​this style is a complete or partial restoration of the motorcycle to its factory appearance. The closer and better the work is done, the better the tuning of IZH Planet 5 with your own hands looks photo:

Do not think that it is so simple, because even for such a relatively new model, it is becoming increasingly difficult to find original spare parts. Particularly expensive are fragile dashboards, original trunks and dented gas tanks. You'll have to hunt for these details. It will be very expensive to restore Soviet chrome and paint all chips and scratches. This style is suitable for true connoisseurs of the brand and those who prefer to spend hours and days in the garage.

Features of electrical equipment

The wiring diagram of IZH Planet 4 is almost completely copied from the Jupiter model that was the first to appear on the factory assembly line.

The only differences are that:

1. The Planet family has one working cylinder, and accordingly the ignition system is designed to ensure its operation;
2. The IZ Jupiter family, unlike the Planet, has 2 working cylinders; accordingly, the wiring diagram has additional repeating elements.

Headlight

IZH Planet 4 is equipped with more advanced lighting devices:

1. Headlight type "European beam" FG137V with glass with an asymmetrical pattern;
2. Low beam mode with lamp A12-45 + 40 W;
3. Modern direction indicators type 16.3726 (lamp power - 25 W).

Photo of IZH Planet 4 model 1986

Thanks to the modernization of the lighting system, as well as the configuration of the motorcycle:

1. battery 6MTS-9;
2. high power alternating current generator 100 W,

The illumination of the road in the flow of traffic has significantly improved, and traffic on public roads has become safer. At the same time, the price of the motorcycle did not change significantly, which brought its sales to a new level of popularity.

Contactless ignition system

The motorcycle used a new contactless ignition system, the operating principle of which was based on the following operating algorithm:

1. The generator rotor generates pulses when rotating;
2. The storage capacitor is charged through diodes (in the diagram below indicated as VI, V5), as well as through a limiting resistor (R1);
3. Passing through the diode (V6), the electrical signal from the sensor winding (3) enters the thyristor (V4);
4. After it opens, the charged capacitor (C1) transfers the accumulated charge to the ignition coil (primary winding - 4);
5. Under its influence, a high voltage pulse is induced in the secondary winding;
6. Through the high-voltage wire, the central electrode of the spark plug receives a charge;
7. A spark between the electrodes ignites the air-fuel mixture in the motorcycle engine cylinder.

The factory instructions contain the original diagram of the contactless ignition system

The electrical wiring of the IZH Planet 4 motorcycle, due to the peculiarity of the contactless ignition system, has differences in the layout of the main components:

1. The electronic unit of the stabilizer and ignition system is placed in a single housing;
2. It is equipped with two plug connectors;
3. In order to increase reliability, the block is filled with polyurethane foam (non-separable version);
4. Its operating parameters are designed to provide a light signal circuit voltage in the range of 11.5 – 14.5 V.

In addition, the use of a 12-volt circuit led to the division of the ignition system into three electrical circuits that differ in voltage levels:

1. A high-voltage circuit consisting of an ignition coil, a spark plug, a spark plug tip and a high-voltage wire;
2. Storage capacitor charging circuit, consisting of a charging winding, connecting wires with plug connectors, BCS and the primary winding of the ignition coil;
3. The sensor circuit, consisting of its winding, connecting wires and plug connectors.

Generator IZH Planet 4

A more advanced generator began to be installed on the new model of the Izhevsk Motor Plant, capable of serving the increased needs of the electrical equipment system, in contrast to the wiring diagram of the IZH Planet 3.

Original factory circuit diagram of the IZH Planet 4 motorcycle generator

Among the design features it is worth highlighting:

1. Eight coils placed in the stator slots;
2. Serial connection diagram;
3. Coating of coil windings with insulating varnish;
4. Original fastening to the stator, made using washers and bent petals.

To identify faults with your own hands, you need an ohmmeter or a universal tester, which can be used to measure the resistance of the windings:

1. If the values ​​of the measured resistances differ significantly, it is necessary to inspect the generator stator to detect broken winding leads;
2. The reason for unstable operation may also be their short circuit. If possible, identified faults are eliminated by soldering.

Recovery process

When the euphoria of the purchase wears off, a lot of questions arise regarding its repair and restoration with your own hands.

The main task of the new owners:

1. Restore the electrical system - and there are no particular problems with this, since the electrical wiring of IZ Jupiter 2 and Planet of the second and third generations is identical and interchangeable;
2. Starting the engine is a more difficult task due to the need to overhaul the power unit and the availability of spare parts;
3. Return the motorcycle to its original appearance. It is also quite complex and, perhaps, the most painstaking work of the entire project.

The video below shows the restored models.

Factory layout for several generations of motorcycles

• Whether to switch to contactless ignition or change the voltage from 6 to 12V is up to you to decide.
• If you have such a desire, and you manage to get your hands on a native Izhevsk generator 281.3701, then the replacement process will be much easier.

central locking

Let's consider the process of restoring the central lock, since in most surviving models it is faulty.

Appearance of the headlights and controls of IZH Planet 2

The difficulty is that finding the original lock is very difficult, almost impossible. Moreover, at 6V, since later the Izhevsk Motor Plant transferred all subsequent models to 12-volt equipment.

This is what the filling of the original 6V ignition switch looks like

Therefore, many motorcycle owners adapt parts from later versions of Planets and Jupiters.

The difficulty of installation in this case is as follows:

• Uncertainty about whether the lock will work;
• How to properly connect wires.

Wiring diagram for IZH Planet 2 to the lock

Headlight

Many owners do not attach importance to adjusting the head light, believing that a working light bulb and intact glass are enough for “driving” during daylight hours.

Using this scheme it will be easy to connect all consumers

In fact, this is not so, and adjusting the light is not only desirable, but also mandatory, especially since it can be easily done independently, spending no more than half an hour of personal time on it.

Scheme for adjusting the angle of luminous flux

If you manage to bring IZH Planet 2 back to life, while maintaining its identity and originality, then our information with color diagrams and photos on electrical equipment is not in vain. We hope that it will provide you with all possible assistance, and there will be one more carefully restored domestic legend on the roads.

Improved ride quality

The icing on the cake, and in our case the final touch of tuning, is the improvement in driving performance. Some of the tuners approached this issue earlier when they sawed the frame of their motorcycle or raised the tail of a future crossover. For the rest, first of all, you should get rid of your original tires. Among its advantages, only wear resistance can be noted, for which you pay with your safety. It is both universal and useless. The lugs are practically useless; if they get into a mess, under normal conditions on the highway it is noisy, but relatively holds the road, turning into a killer on a wet highway.

Therefore, without hesitation, we throw it away and purchase road, cross or all-purpose tires, based on your requirements. The second point is the suspension. If everything is generally clear with the rear shock absorbers, they are extremely reliable and, in addition, have stiffness settings, then the front fork does not leak only for those who have chosen a different brand. There are two ways to get out of this situation. The first is to add thicker oil. The second is to carry out a complete overhaul of the feathers and replace all parts. Both options do not last long, so the most demanding owners simply change the fork to an imported one, while the rest endure all the shortcomings of their iron horse.

These include switches (high-low, turns, engine stop, etc.) as well as brake and neutral sensors and the ignition switch. You can easily “ring” them with a tester, finding out which contact group is not working.

Switching also includes the Izh electronic turn signal relay. Its malfunction is visible by the absence of interruption or no voltage supply to the turn signals.

As can be seen from all of the above, the wiring on Izh Planet is without any special secrets or complex elements, all its parts are easily diagnosed and repairs should not cause difficulties.

Now we advise you to watch the video, which shows in detail and clearly the assembly of the Izh Planet 5 circuit.

When the high or low beam is turned on, the rear light and front marker do not light up. When I turn on the parking light it comes on. Everything seems to be fine with the wiring. What is the reason? Who can HELP.

I think it doesn’t get enough gasoline, maybe the needle fell or the carbure is clogged, or try bending the floats a little))

Why is it that when you pump gasoline, there is little gasoline or no gasoline at all?!

fuck, if there is a lot of gasoline, he definitely won’t go

what can happen if one boiler fails.

If a lot of gasoline goes down, why don't you change the spark plug, it will still get stuck quickly

IF THE OVER-LOADED MIXTURE OF THE PLUGS STOMS IN ANY CASE, AT LEAST SET THE IGNITION OR CONTACTLESS SET

I have the same problem with Planet 5. At full speed while driving, it starts to stall and the charging disappears; if at night, the headlights also go out. Tell me what to do if anyone had such a problem.

maybe the reel is faulty, maybe the generator, maybe the relay, don’t reach full speed, why force the engine?

Maybe I don’t understand something, but how is the bobbin connected to charging? The generator was replaced entirely, and a new relay was also installed. And I love full speed)) And even if the guys don’t drive at full speed either??))

The road version of the IZH Planet 5 motorcycle differed favorably from other domestic analogues by the use of an oil pump, which made it possible to abandon the scheme for pre-mixing fuel with oil.

In addition, subsequent modifications were distinguished by their contactless ignition system, independent of the battery, and modified kinematics.

Differences from the second Planet

For many modern citizens, the information that domestic motorcycle manufacturers worked tirelessly to improve their models in an era of total shortages may come as a surprise.

Note! The fact takes place, moreover, it is supported by official documents, in particular 1970N04P16-17 - this is the outgoing number of the factory newsletter, which described the changes made. In the photo - official materials of the Izhmash Design Bureau

The new generation motorcycle received:

1. Direction indicator lights are a first in domestic practice;
2. Semiconductor relay for controlling direction indicators (installed in the headlight);
3. New size of wheels and tires (3.50x18 versus previous - 3.25x19);
4. New brand increased capacity battery (old one on IZH Planet 2 - ZMT-6);
5. And, of course, more engine power. The power unit now developed 18 hp.

Modifications

But the creator engineers did not stop there and, having released the five-millionth car from the production line, presented a modification of the IZH Planet 3-01.

Mirror and safety arches are the distinctive features of the new modification

Among the innovations it should be noted:

1. Rear passenger footrests;
2. Roll bars;
3. Rearview mirror;
4. New steering wheel design.

IZH Planet 3-01 with wide wheels of smaller diameter - “rural version”

What is the value of this model

Such increased attention to the IZH Planet 2 model is caused by the fact that:

1. in total, just over 246 thousand were produced;
2. and there are few surviving copies left;
3. which only increases its value among collectors.

According to Izhmash, only 246 thousand Planet 2 models were produced throughout the USSR.
Therefore, it was a great success to find preserved motorcycles in garages and sheds of villages and towns (as in the photo below). Moreover, if the previously discussed price has not changed, and the owners give you a bag of spare parts in addition, consider that you have hit the “jackpot”.

Fortunately, you can still find “live” IL with original parts. True, only in this state

Cafe Racer

The style largely repeats the previous one, because it consists of giving the motorcycle an appearance similar to the British models of the 60-70s. A distinctive feature of such motorcycles is the special shape of the seat and tail. For our modification model, we will have to work on the rear part and replace the tank with a more streamlined one. You will also have to change a number of details in general, these are:

• round mirrors;
• one round device instead of a panel;
• monochrome, dim color of the main elements;
• no stickers;
• an abundance of chrome parts (switch feet, turn signals, possibly fenders).
