22. FUEL LEVEL GAGE DOES NOT INDICATE PROPERLY - 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.

a. If fuel level gage (1) reads full, replace fuel gage sender (page 2-662).

b. If fuel level gage (1) reads empty, place terminal (2) in position and tighten screw (3) using 1/4-

inch flat-tip screwdriver.

Step 6. Turn ignition lock switch (4) counterclockwise to accessory. Using multimeter set to 30 vdc scale, place red

probe on fuel level gage pink wire terminal (5) and black probe on cowl support (6). Check for 11 to 13 vdc on

multimeter. Turn ignition lock switch (4) clockwise to off.

a. If multimeter reads 11 to 13 vdc, go to step 7.

b. If multimeter reads less than 11 vdc, repair pink wire in cowl wiring harness (page 2-137).

Step 7. Pull connector (7) out of connector (8). using multimeter set to R x 1 scale, place red probe on fuel level gage

black wire terminal (9) and black probe to black wire terminal (10). Check for 0 ohm on multimeter.

a. If multimeter reads 0 ohm, repair black wire in main and front light wiring harness.

Plug

connector (7) into connector (8).

b. If multimeter reads more than 0 ohm, repair black wire in cowl wiring harness (page 2-137). Plug
