Sequence of work
1. Connect a multimeter between the positive terminal of the generator (red wire) And «weight».
2. Run the engine for two minutes at 3000-4000 min-1 to allow the generator to reach operating temperature (around +80°C).
3. Turn on the side light, radio or fan. This corresponds to a load of 3–7 A. The voltage at the regulator should be in the range of 13.0–14.6 V.
4. If the device shows a higher voltage, the regulator is faulty, it should be replaced. If the voltage is below the specified values, the brushes are worn out. In this case, remove the alternator and have it repaired by a workshop.
