My friend converted his 41 Chevy to 12 volts. Now, high and low beam have switched. The high beam indicator is on when the low beams are on. And when applying the brakes, the dash lights come on. Any ideas?? The amp gauge seems to be working fine. He always had his car hooked up 6 volt neg ground. Now its 12 volt neg ground. Had his original generator converted to 12 volts with a 12 volt reg. Changed all of the bulbs to 12 volt. 1157 bulbs in the rear. No park lights up front. No turn signals on vehicle as of yet. The only bulbs to change were the two rear lights and dash lights. Any ideas??
There is no way that the headlight switch would reverse, unless you are now running Positive ground. Make sure that you have everything connected properly, and also, if you are using a regulator, make sure that you polarize it once it is installed. It could be generating backwards.
sounds like a ground fault, possibly due to higher voltages but it could be a fluke. tell buddy to take a set of booster cables, attach one end to the neg on the battery and the other end to a ground point on the body or frame or both, this is how i find ground faults. they can be tricky, grounding out through switches and other things you might not expect
if no wires were changed one of the bulb sockets has a back feed take a tail light bulb out then the other
Thanks for the info, I told him there might be a bulb problem, but didn't think about polarizing the reg. We'll check and I'll let y'all know what we find.
