An observation I've made, is that there seems to be a belief that there is a need for a "good" ground at the gauge panel (gauges to panel via mounting clamp) for the gauges to function properly. As I was recently correcting problems with my gauges, I searched this subject here and printed the wiring schematic for reference. While looking at the schematic, I noticed that only 4 Items on the gauge panel require an electrical ground contact to the gauge panel. They are the high-beam indicater,2 panel lights and the volt meter.(To complete these circuits the gauge panel needs to be secured to the dash) The oil pressure, coolant temperature, fuel level and of course the air gauge(no voltage required), do not need to be "grounded" at the gauge panel. These gauge circuits are grounded at the sending-unit end.
