ORGANIZATIONAL TROUBLESHOOTING - CONTINUED
TEST OR INSPECTION
If ground terminal (9) is loose, solder using rosin core solder (item 26, Appendix C), long
round-nose pliers, and soldering iron. Assemble combination tail and floodlight (page
2638). Plug terminal (1) into connector (2).
If ground lead is cracked or broken, replace it (page 2137). Assemble combination tail
and floodlight (page 2638). Plug terminal (1) into connector (2).
6. BOTH COMBINATION TAIL AND FLOODLIGHT TAILLIGHTS DO NOT WORK
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.
Check to see if taillights are affected by light switch position (TM 5-2420-222-10).
If taillight work in H1 or H2 positions, but not both, replace light switch (page 2-589).
If taillights do not work in H1 and H2 positions, repair yellow wire in rear light wiring
harness (page 2-137).
