Keeping my 12V generator for the time being due to cost and trying to find one that works. I don't know what it was originally from, but it came with the jeep and worked well before the restoration started. Gener-nator was beyond what I wanted to pay for now. But at least there is more knowledge in the subject out there.

???
Worked before but now it does not. ??
All it did was set. ??
Maybe all the gen. needs is to be reenergized. ??
A jumper wire from the regulator Bat. terminal, brushed to the Gen. field terminal a few times. It should make a spark.
This would re-establish the gen. field residual magnetism that may have went away from setting.

It worked before I took it off to start the restoration, so I assume it still works. However it was a non-Willys generator that was jerry rigged into position. After putting it back into the original mounting configuration, I realized it was not going to fit right without some modifications. So I figured I would either buy a proper MB generator, or the Alternator. I tested the Alt. route since a rebuilt gen and alternator were about the same price.

In the end the alternator didn't fit, and after some more thinking, I realized I only had to shorten down the generator pivot bracket, shim up the pulley, and do a little bit of lathe work on the pulley. All fits well now.

As I recall, rear military brackets came in two lengths. Of course the front mount was in the front engine cover.
And CJs used a generator that might be about the same length as what I think you have.
But, you got it, so guess this is just trivia.
Nothing like a happy ending !
