Troubleshooting Hints - Gauges and Warning Indicators

START DIAGNOSTICS HERE
Perform the checks listed below before performing "System Diagnosis."

1. Check IGN Fuse and ground G200 by noting normal operation of the Heater and A/C Control Assembly.

2. Check Gauges Fuse for open. If open, check for short to ground through CKT 39.

^ Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).

^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
