Headlights...no power

jtbshaw · 03-06-2015, 11:09 AM

Any ideas as to why I am not getting any voltage (low or high beam) to the headlight plugs? Fuses and fusible link are good, I have 12v coming off of the switch, headlight motors work properly....just not getting any juice to either headlight plug.

Any thoughts?

FC? If so check your headlight relays.

Have you confirmed both relays still work? Power passes through both the headlight relay and dimmer relay regardless if the highs are on or not. A quick check would be if the high beam indicator illuminates when they're switched on.

Thanks guys. I will check them tomorrow. Thought I was going to tonight but opted to take my wife out for dinner.

The issue was the headlight relay...or lack thereof one. Wired in a new relay and now HIDs with projector lenses work great.

Thanks for the help.
