Can y'all help me get my cut-out wired correctly? Which terminal does the yellow gen wire go to and the black seems to be a ground. The remaining terminal will be for the wire from the loom. I'm running a 6v system with mags and a battery if that helps.

The end of the case does not look to be T it is adapted from some other. might be later Model A or B. Those wires coming out do not look safe or up to the task. Esp the light colored one, looks like a short about to happen. I will leave the cutout for others to debate, but I would recommend a rebuilt proper T generator or have that one checked and rebuilt. If the wires are that dodgy on the outside no telling the condition inside.

The presence of two connections makes me wonder if one is for the field coil and this generator is off something after 1939, intended to be used with a voltage regulator. It would be interesting to know the internal connections and brush arrangement.

I am going to say no to the regulator type at this point. I think that the other wire is simply the ground end of the field coils. Instead of mount that wire inside to the case, it was simply run out and held in place by by one of the screws holding the cut out. If the 39 up type is anything like my 48, there would have been 3 terminals on the case to mount the wiring harness to. I am pretty sure I have seen that number before on a Model A or B end plate. With out looking inside I would not even guess at this point. Between the two wire, the one that is attached to the end of the field coil would be grounded.

Every T generator I've seen has a post at that point. No wires coming out of the generator. The slotted end of the cutoff is fastened to the post and the one with the screw connected to the wire which goes to the ammeter.

Ryan,

this is not a model T generator.
I saw this before and that one was a construction made with the parts of a Lucas Dynamo inside of a model T generator housing. I did made it work with a three coil Lucas regulator and a warning light.
At the end I replaced it all with an original Model T generator and a FP 12V regulator. This was much easier than installing the other parts in the model T.

Good luck

I think it would be a good idea to buy a rebuilt T generator. The cutout looks like it may work but a new one would the way to go.
There is to much of a mismatch to use what you have. You will better off to get the correct parts and much happier.
