Generator

My 30 Coupe has the generator with 2 wires coming out of the top. What years were these used? Most I have seen have the single post on the top?

Thanks

I have one of this type generator. It's the short nose version. The brush end plate appears to be aluminum with a series of vent holes in the plate. It also has a two piece steel generator pulley.

I was told these generators were used on 1933-1934 four cylinder engines. Have never used it although it appears to be in good condition.

That's the extent of my information. Rather sure someone here on Ford Barn will have all the detailed information you seek.
 
The generator with the wires coming out would not have been origninally supplied with the Model A. That was not one of the styles that was originally used with the car. I cannot speak if it was a later than model A part, or I am guessing a replacement part. I have one of those sitting on the shelf as well.
 
It was a common rebuilders "fix" when the original threaded stud was faulty. No original A or B generator came with two wires.
 
They were used right after the Model A years, but I'm not sure exactly when this generator first started or was last used. One wire is the output wire and the other wire is the ground for the field windings. If the car came with a factory radio, then this generator had a voltage regulator that the field ground wire connected to. The regulator mounted on top of the generator and was oval due to two coils inside, one a voltage regulator and the other a cutout. These voltage regulators are hard to find.

If you use a simple cutout, then you just ground the field wire under one of the cutout mounting screws.

I think Vince had a chart on his website showing this style generator, as well as many others, and telling when they were used.

I think this generator was used 1933 and later on the four cylinder B type engines and sometimes reffered to as the model 46. I now understand that this generator was offered by Ford as the replacement for the model A generator when the generator with the post was discontinued. I have rebuilt several of these generators and installed a post and grounded the fields to the inside of the case as in model A generators. I also swapped out the rear brush plate, front plate and pulley as this is the only real difference.

I believe that the voltage regulator that was used in the forties and early fifties can be used with this generator or the model A generator. Please correct me if I am wrong. I believe that the fields could be grounded to the field connection on the regulator, the post on the generator wire would be connected to the arm terminal on the regulator and the batt terminal on the regulator would connect to the post on the starter. This should give voltage regulation and the third brush could be adjusted for maximum charge. If a person wanted to run 12 volts they would use the 1956 and later voltage regulator. I would like to hear your thoughts. Thanks.
 
The xtra wire is for the oval cutout that has a "voltage regulator", that wire is the ground wire for the field coils.

If you change over to the threaded post you have to hook up the coming from the field windings to the housing (ground), now that wire is probably attached to one of the cutout mounting screws(ground), the wire from the brush goes to the threaded post
