I figured it out. the gauge has a rivet that holds the ground trap on the back. when I tighten the gauge into the backing plate the rivet gets pushed into the gauge hard enough to short out something in the circuit board inside the tach I quess. I used a rivet washer between the gauge and the backing plate on each side and works good now. ?
