4. INSPECT FUEL RECEIVER GAUGE OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Turn the ignition switch ON, check that the receiver gauge
needle indicates EMPTY.
(c) Connect terminals 2 and 3 on the wire harness side con-
nector through a 3.4±W test bulb.
(d) Turn the ignition switch ON, check that the bulb lights up
and the receiver gauge needle moves towards the full
side.
HINT:
Because of the silicon oil in the gauge, it will take a short time
for needle to stabilize.
If operation is not as specified, inspect the receiver gauge resis-
tance.
5. INSPECT FUEL RECEIVER GAUGE RESISTANCE
Measure the resistance between terminals.

lights up.
If the warning light does not light up, test the bulb or inspect wire
harness.
8. INSPECT FUEL LEVEL WARNING SWITCH
(a) Apply battery positive voltage between terminals 1 and 3
through a 3.4±W test bulb, check that the bulb lights up.
HINT:
It takes a short time for the bulb to light up.
(b) Submerge the switch in fuel, check that the bulb goes out.
If operation is not as specified, replace the sender gauge.
9. INSPECT ENGINE COOLANT TEMPERATURE RE-
CEIVER GAUGE OPERATION
