2. Connect the wire to ground (maximum
current). The gauge should read Full.
If conditions 1 and 2 are not met, the

If conditions 1 and 2 above are met, the
problem is with the sender.
To test the sender:
1. Remove the sender from the fuel tank.
2. Connect an ohmmeter from the wire terminal
to the sender body (ground).
3. Move the float through its travel. The
resistance should range from 20-35 ohms
when the float is up. When the float is all the
way down, the resistance should be 240-265
ohms.
