CORRECTIVE ACTION

3. ONE FRONT LIGHT DOES NOT WORK

Step 1.

Check headlight (1) to see that it is tightly mounted.

If headlight (1) is tight, go to step 2.

If headlight (1) is loose, tighten nut (2) using 3/4-inch open-end wrench.

WARNING

Although ignition lock switch must be on and battery ground cable connected to test electrical circuit

voltage, turn off ignition lock 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 equipment.

Step 2.

Pull connector (3) out of connector (4). Using multimeter set to RX1 scale, place red probe on

connector (3) and black probe on front light bracket (5). Check for 0 ohm on multimeter.

If multimeter reads 0 ohm, repair pink wire in main and front lights wiring harness (page

2137). Plug connector (3) into connector (4).

If multimeter reads more than 0 ohm, plug connector (3) into connector (4) and go to step

Step 3.

Disassemble front light (page 2648). Using multimeter set to RX1 scale, place red probe on lamp

positive terminal (6) and black probe on lamp ground terminal (7). Check for 0 ohm on multimeter.

If multimeter reads 0 ohm, go to step 4.

If multimeter reads more than 0 ohm, replace lamp and assemble front light (page 2-648).

Step 4.

Check front light leads (8 and 9) for cracks, breaks, corrosion, and loose ground terminal (10).

If either lead (8 or 9) is cracked, broken, or corrode 1, replace (page 2-137). Assemble

front light (page 2-648).

If ground connection is loose, solder ground terminal (10) using rosin core solder (item 26,

Appendix C), long round-nose pliers, and soldering iron. Assemble front light (page 2-

648).
