Turn ignition switch to RUN position. If charge indicator illuminates, go to next step. If charge indicator does not illuminate, go to step  6 .
  4. Test generator supply voltage circuit, generator harness connector terminal "S" (White wire), for an open. See WIRING DIAGRAMS  . If no problem exists, go to next step. If problem exists, repair circuit as necessary and go to step  9 .
  5. Replace integrated circuit voltage regulator. See OVERHAUL  . After repairs are made, go to step  9 .
  6. Inspect charge indicator bulb. Replace as necessary. Test charge indicator supply voltage circuit, generator harness connector terminal "I" (Red/Blue wire), for an open. See WIRING DIAGRAMS  . If no problem exists, go to next step. If problem exists, repair circuit as necessary and go to step  9 .
  7. Test charge indicator ground circuit, generator harness connector terminal "L" (Yellow wire), for an open. See WIRING DIAGRAMS  . If no problem exists, go to next step. If problem exists, repair circuit as necessary and go to step  9 .
  8. Repair or replace instrument cluster printed circuit. See appropriate INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT. After repairs are made, go to next step.
