My BDK that has VDO gauges is giving me a big problem. The temp. gauge reads 20 to 22C higher than is detected with a temp gun. Also, when I turn on my lights the temp goes up another 5 to 10, turn them off and it goes back down. My
oil gauge reads 2.5 to 3 BARS, but when the pressure is tested it reads 3.5 BARS. When the lights are turned on, it goes down to 2 to 2.5 BARS. Lights off Bars back up. I think I have a short somewhere, any suggestions?
