BODY ELECTRICAL COMBINATION METER
1996 LAND CRUISER (RM451U)
7. INSPECT FUEL SENDER GAUGE OPERATION
(a) Connect a series of three 1.5 V dry cell batteries.
(b) Connect the positive (+) lead from the dry cell batteries to
terminal 4 through a 3.4 W test bulb and the negative ( −)
lead to terminal 5.
(c) Connect the positive (+) lead from the voltmeter to termi- nal 4 and the negative ( −) lead to terminal 5.
(d) Check that the voltage rises as the float is moved from the
full to empty position.
8. INSPECT FUEL SENDER GAUGE RESISTANCE
Measure the resistance between terminals 4 and 5.
Float position: mm (in.)Resistance (Ω )
F: Approx. 15.0 (0.591)Approx. 3.0
E: Approx. 200.0 (7.874)Approx. 110.0
If resistance value is not as specified, replace the sender
gauge.
9. INSPECT FUEL LEVEL WARNING LIGHT
(a) Disconnect the connector from the sender gauge.
(b) Connect terminals 1 and 5 on the wire harness side con-
nector.
(c) Turn the ignition switch ON, and check that the warning
light lights up.
If the warning light does not light up, test the bulb.
10. INSPECT FUEL LEVEL WARNING SWITCH
(a) Apply battery positive voltage between terminals 1 and 5
through a 3.4 W test bulb, and check that the bulb lights
up.
HINT:
It will take a short time for the bulb to light up.
(b) Submerge the switch in fuel, and check that the bulb goes
out.
If operation is not as specified, replace the sender gauge.
