Fuel Sender

The sender is located on top of the fuel tank under the
right, front fender.
1. Remove blue/green wire and black ground wire
from the sender.
2. Remove round head screws and lock washers from
the sender and fuel tank.

Clean any fuel from the sender.
Note: Before taking small resistance readings with a
digital multimeter, short test leads together. The meter
will display a small resistance value. This internal resis-
tance of the meter and test leads should be subtract
from the measured value of the component.
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.

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.
