Charge Indicator Light Always On
- Ensure ignition is off. Disconnect generator connector. If vehicle is equipped with dual generators, disconnect both generator connectors. Turn ignition on. If charge indicator light is on, go to step 7 . If charge indicator light is not on, go to next step.
- Turn ignition off. Connect a DVOM between generator battery terminal and positive battery terminal. Start engine and run at 2000 RPM. Turn on all accessories. Measure voltage drop across output side of charging system. If voltage drop is less than 0.3 volt, go to next step. If voltage drop is more than 0.3 volt, go to step 4 .
- Turn ignition off. Connect a DVOM between generator case and negative battery terminal. Start engine and run at 2000 RPM. Turn on all accessories. Measure voltage drop across ground side of charging system. If voltage drop is less than 0.2 volt, go to step 6 . If voltage drop is more than 0.2 volt, go to step 5 .
- Locate and repair high resistance or open in Red wire between generator battery terminal and positive battery terminal. See WIRING DIAGRAMS . Recheck system.
- Locate and repair high resistance or open in ground circuit between generator case and negative battery terminal. See WIRING DIAGRAMS . Recheck system.
- Replace generator(s). See GENERATOR under REMOVAL & INSTALLATION. Recheck system.
- Disconnect instrument panel connector. Using a DVOM, check for continuity between generator connector (Brown wire) and ground. If continuity exists, go to next step. If continuity does not exist, go to step 9 .
- Repair short to ground in Brown wire between instrument panel and generator(s). See WIRING DIAGRAMS . Recheck system.
- Replace instrument cluster. See appropriate INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT. Recheck system.
