Fun Projects Cut-out Question

I just got the Fun Projects generator regulator/cut-out in the mail and had a question. My original cut-out has terminal lugs on each side to which the wires are tightened down with a little screw. The Fun Projects cut-out has a lug only on one side and a split spade type connection point on the other. It also doesn't indicate which lug is which for connection purposes. Any one else have this problem?
 
The large split blade terminal slides onto the main screw on the generator. The other side connects to the wire from the battery.

Hmmm...main screw. My old cut-out has the generator wire attached to the back lug and the wire to the battery attaches to the front lug. I don't have any kind of main screw thing...it is an actual wire coming out of the generator. Prior owner must have had a problem with the screw post and just fed the wire directly out of the generator. the odd thing is that my original cut out doesn't even HAVE the split spade terminal...it is actually a mirror image of the plain front terminal with a small screw holding the wire in. How very odd.


I wonder if they sell the individual parts for the generator. In the bratton's generator picture these would be parts #: 60 through 66...
 
Sounds like you might have a later generator. Stock looks like the one in the pic and you can see the "main screw".

Hmmm...that generator appears to have the split lug at the FRONT attached to a post. Now I'm really confused... Ha, ha...welcome to the Model A world I guess! :)


I found the terminal post parts on the web. I guess I'll "modify" my generator back to its original configuration. The odd thing is that my current cut-out doesn't even have the split lug on it. PO must have removed the lug because the generator was missing its original terminal post.


Anything different about the later generator that I need to know about?

Good catch. I think the later 30-31 generators might have the post in the rear... Have both at home, I'll have to investigate.
 
There are a few variations of the Ford generators in the early years.Just make sure you read and follow the instructions that come with that regulator.The big thing to remember is,you DO NOT polarize the generator with that regulator in place.Unhook the connections first.If you jump the two terminals with the regulator hooked up,as was always done on an original,you will fry it.
 
Also with Fun Projects regulator:

1. Do not change polarity when installing battery.

2. Do not use 12 volts to jump start a 6 volt car.

Either one will fry most regulators.

Correct. Early long nose - armature post in front, like Ryan's pic. Later short nose - post in rear.

Cutout mount points are off-center; will mount only in the correct orientation on either one.

You have a 1932 or later generator, and it should have two wires coming through a rubber grommet. One is the field ground and gets fastened under the cutout mounting screw, and the other goes to the cutout. You can use a short screw and nut to fasten the wire to the open spade terminal.
 
You are introducing modern electronics into your charging system. Follow the directions exactly as far as setting up charge rates etc. I've had a FP regulator for years and it works excellent but 1 time of reverse polarity incorrect wiring or overvoltage and it WILL turn into a pumpkin. I'm sure you know all this already but for others reading the post I feel it's important to reiterate.
