Earth wire for oil gauge
« on: June 22, 2013, 05:16:41 PM »
Do I need to run a earth wire for the oil temp gauge? The current gauge is earthed to a black out switch only, I can't get the bulb to work like this, if I earth the build on the body as a test it works, so me thinks the black out must not be earthing.  I don't mind doing a bypass if this is what's required
