Re: Need help very stumped on '69 dome light
The dome light circuit is an oddball. It has +12 volts applied at all times through the orange wire. The white wire is a ground which goes to the door and headlight switches. The switches provide a path to ground. It was easier to wire it this way because there is more than one switch and you only have to run one wire to each switch and then ground the switch. With the doors closed and the headlight switch turned clockwise you will have around 12 volts at both ends of the bulb. If you're getting power at the dome light try grounding the white wire with a jumper wire at the plug in the trunk. If it lights up work your way back to the dash using your jumper to ground until you find the problem. Probably just a bad connection somewhere. Good luck.
