Help! Headlights are backfeeding ignition and accy circuit
As the subject implies, I'm getting backfeed to my ignition and accessory circuit when I turn my headlights on.
This is a partially finished project I picked up. There were several loose grounds that have been secured. I don't see anymore.
The headlight switch looks newer, but I'm going to replace it anyway. Because there have already been parts that looked new, but were bad.
I'm getting about 8 volts
When I turn the knob to dim or brighten the interior lights, the backfeed with adjust from 2 volts up to 8.
Any help is greatly appreciated!
