Test J - Improper Charge Warning Operation

  1. Remove instrument cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION. Remove charge system warning light bulb. Check continuity between terminals of bulb. If continuity exists, go to next step. If continuity does not exist, replace charge system warning light bulb.
  2. Disconnect instrument cluster electrical connector C2. See Figure . Disconnect generator voltage regulator 3-pin connector. Measure resistance between instrument cluster electrical harness connector C2, terminal No. 11 (White/Blue wire) and voltage regulator harness connector White/Blue wire. Resistance should be less than 5 ohms. Measure resistance between ground and instrument cluster electrical harness connector C2, terminal No. 11 (White/Blue wire). Resistance should be greater than 10 k/ohms.
  3. If resistances are as specified, go to next step. If resistances are not as specified, repair White/Blue wire between instrument cluster connector and generator voltage regulator connector. See WIRING DIAGRAMS  .
  4. Visually inspect instrument cluster printed circuit for damage, cracks or hot spots. If instrument cluster printed circuit is okay, check charging system. See appropriate GENERATOR article in ELECTRICAL section. If instrument cluster printed circuit is damaged, replace printed circuit and gauge contact clips. See PRINTED CIRCUIT  under REMOVAL & INSTALLATION.
