1965 F100 Blowing Fuses

Howdy fellas,
My '65 is blowing the 14 amp (1 inch long) fuse for my turn signals and break lights (the head lights and tail lights are OK).

Wondering if it is the brake pressure switch.

Any input is greatly appreciated. Thank you.

It is either a short in the wiring/sockets or you are using the wrong flavour of fuse. Check to see what the amp rating is supposed to be for the brake circuit.

Agree with above. I can't see why the brake pressure switch would cause this. More likely it's the turn signal switch.

My 65 F250 has a 14amp for the Radio / Stop lights / Turn signals.

Is yours blowing the fuse when you hit the brakes or when you use the turn signals? Or do you have a radio?

Unplug the rectangular black wiring harness at the fire wall. Push your brake pedal or operate your turn signal switch or both. If it blows when the plug is un hooked then the problem is up in your steering column somewhere. If it does not blow then, check your wiring all the way back to both tail lights and sockets. After thought. Is there a plug for a trailer on the bumper? If so check that out too.
