3. FUEL GAUGE

WARNING

INOPERATIVE

Do not perform testing near fuel tank

with fill cap or sending unit removed.

Fuel may ignite causing injury to

personnel.

NOTE

Before performing test, ensure fuel

tank is full.

IF STE/ICE-R is available, perform

NG 31 gauge test (WP 0018 00).

Test 1. Test for battery voltage to fuel

level sending unit.

1. Disconnect lead 28 from fuel

level sending unit.

2. Set multimeter to a voltage

range that will measure 24

VDC.

to test 3.

Test 2. Test fuel gauge operation.

1. Turn power accessory switch

to OFF position.

2. With lead 28 already

disconnected from sending

unit, touch contact end to

frame ground.

3. Turn power accessory switch

to ON position.

4. Fuel gauge should read empty. 1. If fuel gauge shows empty, go to

step 5.

sending unit (WP 0109 00) and go

to test 5.

2. If fuel gauge does not show full,

replace fuel gauge (WP 0095 00).

Test 3. Test fuel gauge voltage.

Go to WP 0014 00, table 1,

malfunction 1, test 2, and check

battery voltage into fuel gauge.
