Headlights
I'm having some problems with my headlights turning on and off while my 1966 f100 is running. It first started when I had to jump start a buddy and in the middle of doing so the lights started turning off and on,the heater blower motor slowed down and the truck idle slowed. After getting the car started my heater recovered and the truck ran find however my light will not stay on. I checked the ground and it was fine. Any suggestions?

should look something like this
its just a thought. Unless you have converted to a single wire alternator you have a voltage regulator. Its a square box and mine is mounted on the passenger wheel well. If I am not mistaken it has 3 prongs. The headlight switch would be a good idea to check as well.

The wiring harness is the same for both the original and the electronic regulator.
Headlamps turning off/on while driving could be a defective dimmer switch. Next time this occurs, step on it, see what happens.

AFAIK, Ford never offered an electronic generator regulator, as the last year generators were installed was in 1964.
Ford used similar alternators from 1965 into the 1990's, replaced the original points type regulator with the electronic regulator (E2PZ-10316-A) in 1982.
This part number was replaced in 1990 by FOPZ-10316-A.

Lights coming on and off is usually caused by the circuit breaker in the headlight switch. This happens when there is a short in the wiring, headlight switch or dimmer switch. Voltage regulator probably has nothing to do with it..
