Troubleshooting
6Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| Alternator gives 0 Volt | Blown fuse | Replace fuse |
| Alternator gives 0 Volt | No residual voltage | Excite the alternator by applying a 12V battery voltage with a 30 W resistor in series on the + and - terminals of the electronic regulator, respecting the polarities |
| After being excited the alternator still gives 0 Volt | Connections are interrupted | Check connection cables, measure winding resistances and compare with values mentioned in the alternator manual |
| Low voltage at no load | Voltage potentiometer out of setting | Reset voltage |
| Low voltage at no load | Intervention of protection | Check frequency/voltage regulator |
| Low voltage at no load | Winding failure | Check windings |
