Headlight fuses
 

On a 66 C-10, where are the headlight fuses?

And does anyone have a picture of the fuse box showing which circuit each fuse protects?

Thanks,
Mike

Dont think is there a headlight fuse.. Are yours not working? If not you may have a bad connection at the radiator support plug. It gets dirty in there and you may have to clean it. If that is not the problem put a jumper wire where the high beam switch is and see if they go on and if so your highbeam switch is no good and you can use one of those all the way up to the 80's untill they switched to the column high beam swtich..

I don't think there is a fuse for the headlights.

Most headlight switches have a circuit breaker built into them.
So, if you have power to the big red wire to the switch---the problem will be from the switch down to the dimmer or out to the headlights.

If there is no power to the wire (which could be fed from the ignition switch or a buss in the fuse box), the problem will be between the battery / ignition switch / fusebox.
