- Turn ignition off. Check fuse No. 24. If fuse is good, go to next step. If fuse is blown, replace fuse.
- Disconnect generator 4-pin harness connector. Turn ignition on. Measure voltage between ground and generator 4-pin harness connector terminal "IG" (Black/Yellow wire). See Fig 1. If battery voltage is present, go to next step. If battery voltage is not present, repair open in Black/Yellow wire.
- Connect a fused jumper wire between ground and generator 4-pin harness connector terminal "L" (White/Blue wire). See Fig 1. If charging system light does not turn on, go to next step. If charging system light turns on, replace voltage regulator.
