PART TIME Indicator Does Not Illuminate With Mode Selected
NOTE:
This test assumes that transfer case and linkage are operating properly. Following procedure will help locate a short or open in PART TIME light circuit.
- Turn ignition switch to OFF position. Remove and inspect fuse No. 9 (10-amp) from junction block. If fuse is blown, repair short to ground in White/Black wire between instrument cluster and junction block. Replace fuse. If fuse is okay, go to next step.
- Turn ignition switch to ON position. Check for battery voltage at power side of fuse No. 9 in junction block. If battery voltage does not exist, repair open in Black/White wire between ignition switch and junction block. If battery voltage exists, go to next step.
- Turn ignition switch to OFF position. Disconnect negative battery cable. Disconnect transfer case switch harness connector. Check continuity between ground and Black wire terminal at transfer case switch harness connector. If no continuity exists, repair short to ground in Black wire between transfer case switch and ground point. Ground point is located near generator. If continuity exists, go to next step.
- Connect negative battery cable. Turn ignition switch to ON position. Connect a jumper wire between ground and Black/Red wire terminal at transfer case switch harness connector. If PART TIME indicator illuminates, replace transfer case switch. If PART TIME indicator does not illuminate, go to next step.
- Turn ignition switch to OFF position. Remove instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Ensure transfer case connector is still disconnected. Check continuity of Black/Red wire between terminal No. 5 at instrument cluster harness connector C2 and terminal at transfer case switch harness connector. If continuity exists, replace PART TIME bulb. If no continuity exists, repair open in Black/Red wire between instrument cluster and transfer case switch.
