Initial Inspection and Diagnostic Overview

1. CHECK to see that CIG LTR Fuse is not open. If Fuse is open, LOCATE and REPAIR source of overload, then REPLACE Fuse.
^ 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 system (Refer "Troubleshooting Procedures"). Diagnostic Aids
2. CHECK for mechanical binding of linkage.
