TEST OR INSPECTION
24. ONE HEADLIGHT DOES NOTWORK - CONTINUED.
Although KEY SWITCH must be on and battery ground cable connected to test electrical circuit
voltage, turn off KEY SWITCH and disconnect battery ground cable before doing resistance tests
or replacing parts. This will keep you from getting shocked and prevent damage to parts and
Scrape painted surfaces to bare metal before connecting test leads to ensure correct multimeter
Left side hi-beam headlight wire is marked 52 and right side hi-beam headlight wire is marked 52A.
Step 9. Unscrew and take off two wing screws (1) and junction box cover (2). Using multimeter, set to 20 vdc scale.
Connect red test lead to terminal (3) on junction box (4) and black test lead to ground. Have assistant push
LIGHTS switch handle (5) up to on position. Check for 11 to 13 vdc on multimeter. Have assistant push LIGHTS
switch handle (5) down to off position. Disconnect test leads.
If multimeter reads 11 to 13 vdc 52/52A wire (6) must be replaced. Notify Direct Support Maintenance.
Test headlight (7) as follows: Remove headlight (page 2-807). Set multimeter to ohms scale and adjust to
0 ohms. Connect red test lead to terminal (8) and black test lead to terminal (9). Check for 0 ohms on
multimeter. Move block test lead to terminal (10). Check for 0 ohms on multimeter. Disconnect test
If multimeter reads no continuity on terminals (9 and 10), replace headlight (6) (page 2-807).
