- If indicator does not glow when ignition is on, disconnect electrical connector at alternator. Install fused jumper wire between Brown wire of electrical connector and ground.
- Turn ignition on. If indicator does not illuminate, check for voltage supply to indicator. Check for open circuit in wire from alternator to indicator, or defective printed circuit in IPC. If indicator illuminates, replace alternator.
- Start engine. If indicator remains on with engine running, disconnect electrical connector from alternator with engine running. If indicator remains on, check wire from alternator to indicator or IPC for short to ground. Replace alternator if indicator goes out.
