Troubleshooting Hints

1. CHECK Condition of TURN B/U Fuse 16. If Fuse is open, LOCATE and REPAIR source of overload and REPLACE Fuse.
2. CHECK Back Up Lamps for damage to filament or corrosion between bulb and socket.
3. CHECK adjustment of Back Up Lamps Switch.
4. CHECK that Ground G4O1 is clean and tight.
- CHECK for a broken (or partially broken) wire inside of the insulation which could cause system failure 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 Fuse 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 "Troubleshooting Procedures"). Diagnostic Aids
