Its driving me crazy. Bought a new gauge set from NAPA - got the part number from another thread here. Put it in and as soon as the gauge gets power it pegs. I think a short in the wire to the sender.

Run a jumper wire from the sender to the gauge. Does same thing. Run a jumper from the battery and a jumper from the sender. Does the same thing.

What is up? Why would the gauge peg full? This is what the old gauge/sender did that I replaced.

HELP!!!!!!!
