Had a one wire alternator on a 64 Ford 4000, always worked fine.
Put it on an NAA, alternator wont charge. I'm reading battery voltage between the stud and the case, so I know my ground and connections are good.
Revved the motor to max, still won't charge.
Pulled the rubber plug that covered the 2 terminals not used as a 1 wire(battery sense and excite) wired it up like a 3 wire, and it'll charge. (The excite wire i just touched momentarily to the battery stud to get it started charging)
So I guess I've got 2 questions.
Anything I can do to make it work as a 1 wire so I don't have to fool with another wire/diode/light bulb? NAA's had an ammeter instead of a bulb, that's why I wanted to use this alternator.
If not, think it'll be OK to run it hooked up as a 3 wire? Or will I have regulator problems down the road wired like that. When I checked, it looked good, was charging at about 14.5 volts and 10 amps per my clamp on meter.
