16. ONE WARNING LIGHT DOES NOT WORK - CONTINUED

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 3.

Pull warning light lead terminal (1) out of connector (2). Using multimeter set to RX1 scale, place red

probe on warning light lead terminal (1) and black probe on fender (3). Check for 0 ohm on

multimeter.

If multimeter reads 0 ohm, go to step 4.

If multimeter reads more than 0 ohm, replace warning light leads (page 2-766).

Step 4.

If left warning light does not work, pull orange wire connector (4) out of white wire connector (5). If

right warning light does not work, pull orange wire connector (6) out of yellow wire connector (7). Turn

on emergency flashers (TM 5242022210). Using multimeter set to 30 vdc scale, place red probe on

white or yellow wire connector terminal (8 or 9) and black probe on cowl support (10). Check for 11 to

13 vdc on multimeter. Turn off emergency flashers (TM 5-2420-222-10).

If multimeter reads 11 to 13 vdc, repair orange wire (page 2-137). Plug terminal (1) into

connector (2). Plug Connector (4 or 6) into connector (5 or 7).

If multimeter reads less than 11 vdc, plug terminal (1) into connector (2) and replace turn

signal switch (page 2-594).

Step 5.

Disassemble warning lights (page 2626). Using multimeter set to RX1 scale, place red probe on lamp

positive terminal (11) and black probe on lamp base (12). Check for 0 ohm on multimeter.

If multimeter reads 0 ohm, go to step 6.

If multimeter reads more than 0 ohm, replace lamp and assemble warning light (page 2-

626).
