The tach, oil pressure and hourmeter gauges all work fine. Any ideas on bad gauges or bad wiring? The wiring all goes to a junction in the back (the most common one that is normally seen). Thanks a bunch.
Sounds like a wiring issue. More than likely there is some voltage on the ground side. Try jumper wires direct to power and ground on the gauge and see if it changes anything. With the other power and ground wires removed from the gauge of course.
