ELECTRICAL SYSTEM - Continued
Check headlight wiring harness for a minimum 24 VDC at socket C (Figure 1, Item 6) and D
(Figure 1, Item 5).
Turn vehicle MASTER switch ON and turn light switch to SER DRIVE.
Remove headlight (Figure 1, Item 1) from headlight base (Figure 1, Item 3) and disconnect headlight

Figure 1. Headlight Wire Harness Connector.
Are 24 VDC present at socket C and D?
YES - If minimum 24 VDC is present at either circuit C or D, go to Step (2).
NO - If no voltage is present at both circuits C and D, refer to vehicle electrical wiring diagram, control wiring
harness and rear wiring harness, and troubleshoot circuits 17 and 18.
Check for ground continuity.
Check for ground continuity between ground lead of headlight harness and vehicle ground.
Is there continuity to ground?
NO - If an open circuit is indicated, check for loose or missing hardware and dirt or paint. Tighten or replace
missing hardware, and clean surface where ground lead is connected.
