When I turned the parking lights on the temp and oil gauges started slowly rising. At idle the oil was at 80 and the water which is usually 175 was around 200. went down as soon as I turned the lights off. It's a 69 Charger, using the same gauges and headlight switch that came with it. All new wiring harnesses. Is this some type of resistance or grounding problem?? My Dad always told me, when setting goals " avoid disappointment, aim low".
