8. INSPECT TACHOMETER RESISTANCE
Measure the resistance between terminals with fixing pointer to
the stopper.
Tester connectionResistance (W)
A - B250
C - D250
If resistance value is not as specified, replace the meter.
9. INSPECT FUEL RECEIVER GAUGE OPERATION
(a) Disconnect the connector from the main 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 receiver gauge needle moves toward 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.
10. INSPECT FUEL RECEIVER GAUGE RESISTANCE
Measure the resistance between terminals with fixing pointer to
the stopper.
Tester connectionResistance (W)
A - B250
C - D250
If resistance value is not as specified, replace the receiver
gauge.
11. INSPECT FUEL SENDER GAUGE RESISTANCE
Measure the resistance between terminals 3 and 2 for each
float position.
Float position mm (in.)Resistance (W)
F: Approx. 91.1 (1.36) ± 3 (0.12)Approx. 2.0 ± 1.0
1/2: Approx. 34.2 (2.06) ± 3 (0.12)Approx. 26.1 ± 3.0
E: Approx. 30.8 (5.31) ± 3 (0.12)Approx. 48.7 ± 1.0
If resistance value is not as specified, replace the sender
gauge.
