Troubleshooting
6Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| Battery and A.D. lamps of Fast Check should light if red (+) and black (-) harness leads are properly connected | Check wiring to 1CR, replace uni-board | |
| CRK. lamp alone does not light (voltage not conducted to starter circuit) | Replace uni-board, fix 1CR relay wiring or replace relay | |
| No or low AC output | Blown fuse on sensing leads V7, V8 and V9; regulator board or SCR module overcurrent condition; exciter field issue; controller issue; stator winding problem; rotor resistance or ground issue. | Check for blown fuses. Check controller and exciter field. Inspect stator windings, rotor resistance, and grounding. |
| Generator Set will stop. | 3-Amp fuse 'blows'. | Check fuse. If blown, replace the fuse and attempt to restart generator set. |
| Unit will not crank with a blown 15-Amp fuse. | Blown 15-Amp fuse due to overcurrent in CR and 1CR relay contacts from a short in the wiring or engine accessories. | If this fuse blows while the generator set is running, the unit will shut down. |
