Generator (Opel Kadett E)

The generator does not require any special maintenance. Every year of operation or every 15,000 km of mileage, check and, if necessary, adjust the tension of the generator drive belt.

Precautions when handling the generator

Never short-circuit the excitation coil terminal of the voltage regulator power supply circuit or its connecting wire to ground.
Do not under any circumstances rearrange the wires connected to the voltage regulator.
Do not disconnect the voltage regulator or battery while the generator is running
It is prohibited to remove the generator without first disconnecting the wires from the battery terminals
During generator operation, it is prohibited to disconnect the voltage regulator from the generator ground, as this will lead to immediate failure of the regulator.
It is prohibited to test the generator and voltage regulator on a vehicle or on a test bench unless the battery is connected to the generator circuit.
Before checking the generator's performance, make sure that the battery is in good condition and charged.
When charging the battery directly on the vehicle using a charger, be sure to disconnect the wires from both of its terminals.
When connecting the battery, pay special attention to the fact that its negative terminal is connected to the ground.
In all cases, a change in polarity during connection leads to failure of the rectifier diodes of the generator and voltage regulator.
Before carrying out electric welding work on a vehicle, disconnect the wire from the negative terminal of the battery and the wire from the generator.
