Troubleshooting
6Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| Excessive overheating of one or both bearings (temp of bearings over 80°C) (With or without abnormal bearing noise) | If the bearing has turned blue or if the grease has turned black, change the bearing. | |
| Excessive overheating of alternator frame (temperature rise of more than 40°C above ambient) | Air flow (inlet-outlet) partially clogged or hot air is being recycled either from alternator or prime mover. Alternator is functioning at too high a voltage (over 105% of rated voltage on load). Alternator overloaded | |
| Too much vibration | Misalignment (coupling) Defective mounting or play in coupling Incorrect balancing of shaft (Engine-Alternator) | |
| No voltage at no load or startup | Connect a battery of 4 to 12 volts to terminals E+(F+) or E-(F-) respecting the polarity on the A.V.R for 2 to 3 seconds. The alternator builds up and voltage is correct when the battery is removed. | |
| Lack of residual magnetism in alternator | - Check the connections of the sensing leads to the A.V.R. - Faulty rotating diode - Short-circuit on rotor windings | |
| Voltage collapses during normal operation | Check the AVR, the surge suppressor, the rotating diodes and replace any defective part |
