DIY generator repair toyota

In detail: DIY repair of a Toyota generator from a real master for the site my.housecope.com.

A special device is used to convert mechanical energy into an electrical form. Generators Toyota Corolla versions with a body 110, 120 and 150 three-phase type, with electric excitation, with a built-in rectifier unit. The voltage regulators included in them have an electronic principle of operation.

The operation of the generator on the Toyota Corolla is necessary to ensure uninterrupted and timely supply of current with a certain power. In addition, during operation, it must also provide charging of the battery.

This unit must have a sufficiently high strength, the required power reserve (for E120 models it ranges from 60 A / h to 82 A / h, depending on the engine size, and is selected for a specific model, taking into account the year of manufacture), small dimensions and weight, and Tot - differ in a low noise level and created radio interference.

Malfunctions in the operation of the Toyota Corolla 120 generator of the body and all other models can be eliminated both with their own hands and with the help of the experience of service station specialists. Usually, with a low mileage on models starting from the E11 version, which is about 50 thousand kilometers, you will have to replace the alternator belt or tighten it, make other repairs to ensure normal and efficient operation of the unit.

The operation of the Toyota Corolla E150 generator, like other units of this brand, begins immediately after the engine is started, and during operation it constantly recharges the engine battery, preventing it from being completely discharged. Its operation is based on the well-known principle of electromagnetic induction, according to which the magnetic flux, passing through the winding of a copper coil, at its terminals provokes the formation of a voltage, in magnitude directly proportional to the speed of rotation.

The generator set of the Corolla 120, as well as models with a different body (for example, the Fielder 14, Corolla 121 models), is located in the front of the engine and is activated by the crankshaft. Closed bearings, on which the shaft is installed, are designed for the entire period of operation of the car, without additional lubrication.

With a high mileage Toyota Corolla E150, as well as older versions of the car, it is recommended to check and, if necessary, repair or replace the unit. The fact that there is a malfunction on the generator may be indicated by:

Battery discharge lamp that does not go out after starting the engine. This indicates that the belt has weakened (should be tightened) or the reason is in the unit itself (replacement of worn brushes is required, a breakdown in the winding, it is necessary to change the diode kit).
No power is supplied to the battery, the cause may be an oxidized terminal, a loose belt, an inoperative battery.
The battery is being recharged - any of the faulty elements of the mechanism may be the cause.
The appearance of a characteristic whistle in the area of \ u200b \ u200bthe generator is most often due to a strong degree of belt tension and a high load on the bearing.

Any repair and replacement must be carried out only after the vehicle is completely de-energized with all the terminals disconnected from the battery.

In situations where it is not possible to repair the device, it is replaced.

If the performance check showed the need for replacement, then in order to do this, the old generator should be removed. This will require tools such as a flat head screwdriver, 10 and 12 wrenches, and special tools to remove the motor mud flaps.For the Corolla after 2007, it is necessary to first remove the front wheel on the right, as well as the mud flaps (lower and right). Then you should remove the decorative cover from the motor along with the front lining. A wire with a negative terminal is disconnected from the battery. The block is disconnected from the harness. Next, you need to clamp the clips on the cap and remove its cover. Unscrew the power cable retainer and disconnect it. Loosen the belt to the required level by removing it from the pulley. Loosen the lower and upper bolts that secure the unit and remove it.

After removing and carrying out repair work, install the parts in the reverse order, while tightening the belt of the device to the required degree of tension and adjusting the remaining units.

Repair of the Toyota Corolla generator is carried out after its dismantling, and for any repair work you need such tools as: a 12 key and a 10 head, a Phillips screwdriver, a screw puller, a hammer, as well as a vernier caliper and a tester to check the parameters.

First, a revision of the rotor performance is performed. It is checked for the integrity of the windings using a tester. If there is a break, then the rotor itself must be replaced. The designations on the tester, when the test is carried out, should be from 2.3 ohms to 2.7 ohms, and the presence of an infinity value indicates damage to the winding. To make measurements, three nuts are unscrewed on the removed generator, the back cover and the insulation sleeve are removed.

Next, the operation of the rectifier diodes is checked. To do this, control their ability to transmit current in only one direction. If the chain runs in both directions, replace the block.

Sometimes it may also be necessary to replace the Toyota generator brushes, this is important in the case when their protrusion in the free state exceeds 4.5 mm. Then the brush holder is replaced.

Due to natural wear and tear and long-term operation, it may be necessary to replace the alternator belt, which is also required in the event that it is torn.

You should buy a generator belt specifically for a specific Toyota Corolla model, taking into account its year of manufacture, engine and body, since depending on these parameters, the characteristics of the belts change - density, length and width.

Before replacing something, all protective elements are removed to get to the engine pivot bolt. The bolt is squeezed out and the old belt is removed. The new one is put on the pulley almost by touch, since there is very little free space here. In order for it to hit exactly on its correct site, it is necessary to strictly precisely set it in place. To do this, it is imperative to remember how it was put on when removing the old belt. After installation, the belt should be tightened to the required tension, checking this parameter with special devices.

Regardless of whether the Corolla is right-hand drive (right-hand drive was produced for the Japanese market) or left-hand drive - the stable and correctly selected generator power will ensure the efficient operation of the car. This parameter is taken into account when replacing the generator. All work related to this irreplaceable mechanism in a car can be performed independently, but it is better to seek qualified help from specialists who, in addition to experience, can guarantee the correct implementation of all actions.

The story of the owner of Toyota Carina E - just like that. The output of the generator, which is intended for lamps, must not be allowed to connect the other two wires.

Re: Generator From Toyota. the generator has three chips (see Fig. 4) S connection to the onboard network, what is it for? tell me which one to connect to in our VAZ.

The steadily popular TOYOTA cars are traditionally equipped with Nippon DENSO generators, which, despite their similarity with the units of other world brands, have their own design features, and therefore individual ways of diagnosing and eliminating malfunctions .... In general, generators of this brand generate a voltage of 14V at the output and, depending on the modification and size of the stator, provide operation with a load of 45, 55, 65, 70, 75, 80, 90, Amperes.

In order to prevent errors and simply to simplify operation, the assignment of the main pins on the plug strips of Nippon DENSO products is traditionally indicated on a tag located on the cylindrical part of the case. As for the design, a voltage regulator is located under the metal casing that covers the end of the cover from the side of the slip rings, the rectifier unit and the brush holder, all these units are independent structural units.

Owners of a TOYOTA car quite often begin to doubt the health of the generator, as such, after the battery lamp stops burning on the dashboard, forgetting that the problem may lie in the lack of charge control, and in order to more accurately understand the reasons for what is happening you should carry out an initial diagnosis: In addition, it does not hurt to evaluate the operation of the loading system, for example by turning on the heated glass and headlights.

If everything is fine, we continue to search for a malfunction, not forgetting that on various TOYOTA modifications you can find connectors that are different in shape and number of wires, although in essence they are, in general, identical and the verification of their individual terminals is performed in the same way. In other words, the battery lamp is constantly on and the battery may be overcharged due to the lack of normal communication and the voltage may rise above 14.5V.

A negative result indicates a circuit breakdown or burnout of a standard light bulb. Excitation of the generator occurs through the IG terminal, respectively, the absence of voltage on it indicates a generator failure. Please note that if the voltage at terminal S is constantly present, then to check L and IG, you must turn on the ignition. Only after the initial diagnostics and its positive results were not detected, it makes sense to make a decision to remove the generator and perform its fault detection, in which: In addition, we check the stator and rotor windings for short circuits to the case.

My bearing is screwed up. In the repair of generators, the price tag was simply not real. I decided to try to disassemble and change myself.
Removal is described here. I got by with a little blood.

I will also add useful information so that it is clear what was discussed.

The number of the original generator, which was sorted out: 27060-23030
Other designations from the sticker: 12v 102 211-1680 34 5

And so we have a generator from Yaris. We proceed to disassemble it.
First of all, unscrew the pulley. There are just legends about him, people almost carry him to a tire fitting in order to unscrew

And then screw it up. As I have always done in audi and folk, simple and in 1 minute. We put the generator on the table. We put the spanner on the nut. We put on the head and the knob on the tip of the rotor. The last we rest against the table, we press the generator with our left hand, right. Unscrew the pulley once. Everything. We twist in the reverse order.

Despite the fact that Japanese Toyota Corolla cars are of good quality and performance, they sometimes have problems with the generator. This is influenced by the quality of parts, fuels and lubricants and the operating conditions of cars in Russia.

Despite the fact that Toyota Corolla is a fairly reliable car, the owners of this car still face problems with the generator.

The generator for the car is one of its main components. Its tasks include the processing of mechanical energy into electrical energy. All on-board electrical devices of the car are powered from this energy, the battery is recharged. In the event of a generator failure, the car in the literal sense of the word will stop, all systems will stop working.

Consider how to check the performance and repair the generator in a home garage.

At the first sign of a malfunction in the electrical system, the fuses and wiring are checked. And if everything is fine with them, then the alternator belt is checked for wear and tension. If the problem is in the belt, it is loosely tensioned, then it will be enough to tighten it. However, if it has traces of severe wear, abrasion, cracks, then it is necessary to replace the alternator belt. It is important to remember that before carrying out any repair and diagnostics work, disconnect the vehicle from the power supply. To do this, you need to disconnect the car from the battery.

In order to dismantle the old belt, you need to remove all protection from the engine and get to the pivot bolt and squeeze it out. This will loosen the belt tension and release it easily. Next, you need to put on a new one in its place. To do this, pull back the pivot bolt and put on a new belt. After all, check the tension, if necessary, adjust the tensioner to loosen or, conversely, tighten the new belt tighter. Do not forget that both excessive and weak tension have a bad effect on the operation of the car. In the first case, the bearings suffer, in the second, the entire electrical system of the car.

This applies not only to Funky and Verso with 1300 engines, well, everyone who has a 70 amp generator. It just weighs a little differently on other cars. And whoever has more than 70 just different bearings, and the rest is the same.

And so, something makes a noise, whistles and podlazylyat. We reset the belt as usual (by loosening the two bolts of the generator mounting - upper and lower, we push the generator in front and remove the belt, start it up - it does not make noise. We turn the pulleys in turn with our hands (well, of course, those that are spinning) and oops, the generator emits not normal when the pulley rotates sound On a normal generator, when rotating, you can hear almost nothing except a slight rustle of brushes on the collector, and no knocks are felt on your hand.

It is necessary to change the bearings, and here you will find a trap from Tavota. You will have to determine what kind of generator you have for 70A roofing felts, or 80-90A roofing felts, the fact is that they have different bearings.And by code and wine / frame, we get both. It was not possible to determine the power from the tags on the generator and I chose 70A for luck and was not mistaken.

This is obtained from the front bearing:
