Test J: Charge Warning Indicator Always On/Inoperative: ZX2
- Remove instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Remove charge warning indicator bulb. Check continuity between bulb terminals. If continuity exists, go to next step. If continuity does not exist, replace bulb. Retest system operation.
- Disconnect White instrument cluster 12-pin harness connector C258. See Figure. Disconnect generator voltage regulator 3-pin harness connector C159. Measure resistance of White/Blue wire between White instrument cluster 12-pin harness connector C258 terminal No. 11 and generator voltage regulator 3-pin harness connector C159. Resistance should be less than 5 ohms. Measure resistance between ground and White instrument cluster 12-pin harness connector C258 terminal No. 11 (White/Blue wire). Resistance should be more than 10 k/ohms. Measure resistance between ground and White instrument cluster 12-pin harness connector C258 terminal No. 11 (White/Blue wire). Resistance should be more than 10 k/ohms. If resistances are as specified, go to next step. If resistances are not as specified, repair open or short to ground in White/Blue wire between appropriate instrument cluster harness connector and generator voltage regulator 3-pin harness connector. See WIRING DIAGRAMS . Retest system operation.
- Visually inspect instrument cluster printed circuit for damage, cracks or hot spots. If instrument cluster printed circuit appears okay, repair charging system concern. See appropriate GENERATORS & REGULATORS - ESCORT article in ELECTRICAL. Retest system operation. If instrument cluster printed circuit appears damaged, replace printed circuit and gauge contact clips. See PRINTED CIRCUIT under REMOVAL & INSTALLATION. Retest system operation.
