Autometer Gauges Needles Jump with turn Signal


Asked by May 19, 2011 at 04:30 PM

Question type: Maintenance & Repair

I have a 1947 plymouth not original. It has a chevy 350 motor and a 12 volt system. I took out the original gauges and replaced them with autometer gauges. They work fine. When I use the turn signal the needles on the oil water and voltage gagues jump with the signal light. The gas gauge is fine. I thought it could be a ground. The gauges work fine except for the needles jumping when the turn signal is on. So far I can't find a solution to this. It's really not a problem because as soon as the turn signal is off the gauges work fine. If I can correct it that would be better..
Any help would be appreciated.
