When I switch on my Nav Lights (one of about 10 accesory switches on dash)my guages go haywire and show incorrect readings (temp, battery, speed, oil pressure, etc.) When I switch the Nav Lights off, they return to normal. None of the other switches cause this to happen.<br /><br />Looking behind the dash, I was a little concerned with the fact that I had no idea with what I was doing and thought I would throw it out here to get some clue on what to look for. Thanks for any suggestions, I'm very impressed with the quality of answers on these boards.
