I got the car out of the shop. They checked all the wiring. The sending unit is fine, they put an electric gauge new in the box, not stock but hooked up an electric gauge new to the wires that go to the cluster head, and it works just fine. They got it limited to the head cluster. I put on a new printed circuit board. I tried another gauge and it did not work. I am wondeirng if the head is not grounding out well but if that was the case would not the other gauges be giving me issues? Not sure where to go from here. Thanks for any help.
