Ok this is the only pic I could find of my gauges.
I had trouble with our gauges and ended up taking the gauges apart (yes drilling out the rivets) then fixed some burt traces on the circuit board, then drilled little holes on the face of the gauges and put in needle stops. I used tooth picks painted black and superglued into the holes. The needles would viberate down too low on the tow to and from the lake and the gauges didn't have enough power to pull the needles back up into the operating range. Then I also added in another power wire off the switch and a ground all the way to the battery. Knock on wood I haven't had any more gauge problems.
