Voltmeter INSPECTION OF VOLTMETER Compare the tester and voltmeter indications. If error is excessive, replace the voltmeter. Fuel Gauge INSPECTION OF GAUGE 1. INSPECT RECEIVER GAUGE OPERATION (a) Disconnect the connector from the fuel sender gauge. (b) Turn the ignition switch on. Check that the receiver gauge needle moves to the empty position. (c) Connect the terminals 3 and 4 on the wire harness side connector through a 3.4 W test bulb. (d) Turn the ignition switch on. Check that the bulb lights and receiver gauge needle moves towards the full position. HINT: Because of the silicon oil in the gauge, it will take a short time for the needle to stabilize. If operations are not as specified, remove and test the receiver gauge. 2. MEASURE RECEIVER GAUGE RESISTANCE Measure the resistance between terminals. Between terminals Resistance (Ω) IG – U Approx. 102.7 IG – E Approx. 167.2 U – E Approx. 64.5 If each resistance value is not as specified, replace the receiver gauge. 3. INSPECT SENDER GAUGE OPERATION (a) Connect a series of three 1.5 V dry cell batterys. (b) Connect the positive (+) lead from the dry cell batterys to terminal 3 through a 3.4 W test bulb and the negative (–) lead to terminal 4. (c) Check that the voltage rises between terminals 3 and 4 as the float is moved from the top to bottom position.
