Troubleshooting Hints - Gauges and Warning Indicators

1. Check Fuse 39. If open, check CKT 39 for short to ground.
2. Check any inoperative indicator bulb.
3. Make sure grounds G113, G201, G203 and G301 are clean and tight.
^ 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 (refer to General Troubleshooting Procedures). Diagnostic Aids
^ Refer to System Diagnosis. System Diagnosis
