Charles, A good place to start is by taking the sender wire off at the
sender at the sender and turning your key on.The needle should go to the
full side of the guage, then ground the sender wire and the needle should
go back to empty. If this happens your problem is at the sender. Check to
make sure that your sender has a good ground to the cab. If the guage
doesn't move check these common problems.
1) Make sure that the hot wire never touches the post on the full side of
the guage.
2) Make sure the guage cluster has a GOOD, clean ground to the back of the
dash where they bolt together.
3) Make sure that the guage insulator is on the outside of the housing
between the housing and the nuts.
4) Make sure that the cluster housing is clean, bare metal on the inside
where the guage mounts to the housing.
If you still have problems, call me and we will get it working. Thanks,
David
