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.

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.
