Initial Inspection and Diagnostic Overview

PROCEDURE
^ Check I/P Fuse Block Fuse #32, Horn Fuse. If 32 is open, check for a short to ground in CKT 1340.
^ 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. These circuits maybe 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.
