Checking the voltage regulator

Troubleshooting Battery, their causes and remedies

1. Connect the meter between the positive terminal of the generator (red wire) and "weight".

2. Run the engine for two minutes at a frequency of 3000-4000 ^min -1, the generator has reached operating temperature (about +80 ?� C).

3. Turn the marker light, the radio or a fan. This corresponds to a load of 3-7 A. The voltage across the regulator should be within 13,0-14,6 V.

4. If the device indicates a higher voltage, the controller is faulty, replace it. If the voltage is below these values, worn brushes. In this case, remove the generator and repair workshop.
