Fuel Sender
The fuel sender is located on top of the fuel tank.
Testing
1.Remove white wire and black ground wire from the sender.
CAUTION
If testing circuit wiring and fuel gauge, make sure wire connections are secure before turning igni- tion switch ON to prevent an explosion or fire from sparks.
2.To test the circuit wiring and fuel gauge, connect white and black wires and turn ignition switch to ON. Fuel gauge needle should point to the right edge of the green area (full). Turn ignition switch OFF and continue testing fuel sender if circuit wiring and gauge are accept- able.
3.Remove screws and lock washers that secure the sender to the fuel tank.
4.Remove sender and gasket from the fuel tank. Clean any fuel from the sender.
NOTE: Before taking small resistance readings with a digital multimeter, short meter test leads together. The meter will display a small resistance value. This internal resistance of the meter and test leads should be sub- tracted from the measured value of the component.
CAUTION
FULL POSITION
EMPTY POSITION
Figure 35
Make sure sending unit is completely dry (no fuel on it) before testing. Perform test away from the tank to prevent an explosion or fire from sparks.
5.Check resistance of the sender with a multimeter (Fig. 35).
A.Resistance with the float in the full position should be 27.5 to 39.5 ohms.
B.Resistance with the float in the empty position should be 240 to 260 ohms.
6.Replace sender as necessary. Reinstall sender into fuel tank.
7.Reconnect wires to fuel sender. Apply
