Default Basic trouble shooting 32 generator

Ok. I have no clue when it comes to electricity. I am not getting a charging on the amp meter when running. I do need to replace the wiring harness, and have it ready to go, but how do I know if the generator and cut out are operating correctly? And if it is not, who rebuilds them?

I think Autozone could test it. I think grounding the lead to the cut out should make it go full charge.
The cut out just isolates the gen so not to run down the battery when parked.

Jim,
Arlington Armature in Springfield, VA can test the generator. They are relatively local to you. They've been in business for many decades. Guys in the local V8 club have used their services.

Quick and easy check; start engine, run at above idle speed [generator won't charge at idle], use a jumper from one side of cut out to the other. See if ammeter reads...Report back

Grounding the lead to the cut out is not the correct information, so don't do that. What Brian said is OK providing the cut out is an original Ford unit and not a Fun Projects voltage regulator replacement which looks just the same as the original unit. Better to disconnect both cut out wires and join them together with the engine on a fast idle. If you still have no charge then the generator is faulty. Regards, Kevin.

A CUT OUT IS JUST A SET OF POINTS that when the ignition switch is Off they are open, IF THEY STICK CLOSED ANB YOU SHUT IGNITION OFF the AMP gage will get burned out ,! Been there done that 1 A funspot cut out may be a better choice.

If you have a stock generator...it has a third brush built in that is adjustable. Remove the band around the generator and it should be the brush that is facing you. "Push" it with a screw driver one or way or the other and then start the car and see if there is any difference in the reading. If it is showing more of a discharge, turn the car "off" and adjust the brush in the other direction. Start the car again and see if the ammeter is charging more this time. If there is no difference the readings...you may have a generator problem or a wiring problem.
Good luck, Pat

If you take the belt off and put power to the output post the generator should "motor", if it doesn't there is a internal problem

If there are 2 wires coming out of inside one is a field ground that needs to be grounded unless it is connected to a oval cutout that has a voltage regulator too (many that were rebuilt got converted to this)

Jim,


It would help if you shared which '32 generator you have; four or V8 and original (no wires, just a threaded stud protruding) or later (with protruding wires)?
