Schematic Of The Number 1 Auxiliary Relay. | |
If the EMC, RHC and CCM are not operating, and/or the Right Hand Console, Turn Signals and Front Console circuits have lost power do the following.
- Check the following fuses for continuity; Main fuse #1 (MF2); Key Start fuse (F26); Right Hand Console fuse (F21); Turn Signal fuse (F24); Front Console fuse (F22) and the VPWR fuse (F23). Is any fuse open circuit?
- YES, replace fuse, operate machine, and check fault codes. If machine operates and no fault codes are present, the repair is complete. If new fuse fails check for short circuit.
- NO, go to Step 2.
- YES, replace fuse, operate machine, and check fault codes. If machine operates and no fault codes are present, the repair is complete. If new fuse fails check for short circuit.
- Check wiring for continuity per schematic. Is there continuity?
- YES, check Key Start switch and Aux #1 relay for proper operation. Replace component if failed. Operate machine and if no fault codes are present, the repair is complete.
- NO, repair or replace open wiring. Operate machine, and check fault codes. If machine operates and no fault codes are present, the repair is complete.
- YES, check Key Start switch and Aux #1 relay for proper operation. Replace component if failed. Operate machine and if no fault codes are present, the repair is complete.
