Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems

Go to Step 3

1. Ensure that the battery is charged.
2. Disconnect the connector for CKT 25 (BRN) at the generator. If equipped with dual generators disconnect both generators.
3. Connect a J 36169-A fused jumper wire between the generator connector cavity B (W/ 100 Amp generator/dual generators) or cavity L (W/ 124 Amp Generator) and a known good ground. If equipped with dual generators, connect to each generator one at a time.
4. Place the ignition switch in the RUN position.

Is the Charge indicator lamp lit?
