During the operation of the car, sooner or later, it is necessary to verify the correctness of the operation of the generator. The best way to check the generator and troubleshoot will be a visit to a specialist auto electrician. However, the simplest malfunctions Any car enthusiast is able to diagnose independently. This will require the simplest tester, it is the "multimeter".
1
First of all, check the radio regulator relay, on the car slang - "tablet". From the correctness of its work depends the stability of the voltage in the onboard network of the car. We translate the tester to the "Distant Voltage Measurement" mode and start the engine. By connecting the tester to the battery terminals, measure the voltage at idle. It must be within 4-14.2 volts. Smoothly raising engine speeds, follow the voltage change. Oscillations should not exceed + \\ - 0.5 volts. If the measurement values \u200b\u200bcome out for the specified limit - the regulator relay is not properly and is replaced.

It is also necessary to check the rectifier bridge of the generator. It consists of six semiconductor diodes. Check the conductivity of each DOCU diode. We translate the multimeter to the "Sneveling" position and in turn concerning the contacts of the contacts of each diode. If the tester makes a beep - the diode passes through itself, if not - does not miss. Those. The diode in one position of the polarity of the probe should flow, in the other - should not. If at least one diode "calls" in both directions or does not "be ringing" in any, then the diode bridge is subject to replacing assembly.

Checking the stator generator winding is to estimate its state of mechanical damage and closing the generator body. First of all, it is necessary to disconnect the conclusions of the stator winding from the diode bridge. We translate the tester to the "Resistance Measurement" mode and measure the resistance between the generator body and any conclusion of the stator. The best result when it approaches infinity. If the tester shows less than 50 kiloma, then it remains long to live a generator.

The completion of the generator verification operation will be checking the stator. Check it on mechanical damage and winding resistance. We translate the tester to the "Resistance Measurement" mode and measure the resistance between brush rings. It must be several Ohm. If it is zero, then in the "short circuit" winding. If the resistance tends to infinity, then in the "opening" winding. In both cases, the rotor is not operational - changes only in the collection.
We hope that this simplest instruction will help you spend express diagnosis even in "field conditions". Good luck on the roads!
