Fuel Gauge: Testing and Inspection
INSPECT FUEL RECEIVER GAUGE OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Turn the ignition switch ON, and check that the receiver gauge needle indicates EMPTY.
(c) Connect terminals 2 and 3 of the wire harness side connector through a 3.4 W test bulb.
(d) Turn the ignition switch ON, and 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 the operation is not as specified, inspect the receiver gauge resistance.
