Running Lights Going out when I turn headlights on
I have just restored my 1965 ford F-100. I'm having a issue with the running lights. When I pull the head light switch half way to turn them on they work, but when I turn the headlights on they go out. I don't see any wring issues, but my best guess is I have a bad light switch.
Any trouble shooting or suggestions would be greatly appreciated.
That's the way the operate but you can change that if you want. If you run a jumper on the headlight switch from the tail lamp circuit to the parking lamp circuit, the parking lamps will be on whenever the tail lights are on.
