Mf202 alternator not charging with pictures

So background is its a 1965 MF 202. The alternator quit on me a month or so ago and since then I have tried two different alternators with no luck. The one alternator was a CS130 wired in 2 and 3 wire setups. The one today is a 10si single wire that I had to rig up to secure the top, but the belt was tight and still didn't charge.

I'm attaching pictures of the original alternator that I can't read the part number off of as a reference. It had the red wire from the 4 pin tied into the charge lug of the alternator along with the main battery feed and the ignition wire off the tractor ignition went to the brown or brown/white wire on the 4 pin. As y'all can see the original is secured at 12 oclock and 4-5 oclock.

The white wire coming off the tractor is to the battery and the black is ignition.

For the single wire alt. its secured at 12 and 6 oclock. I was able to secure the 6 oclock and rotate the top to the steering post and temporary secure with bailing wire. I only connected the main white battery wire to the alt lug. Still it didn't charge.

I'm at a loss of what to try and have searched the forums for an answer with no luck.

YT sales have an alternator with the ears at 12 and 6 oclock that they claim works for the MF202, but the sales guy had no idea when I called them today.

The alt that YT sells is the ADR0382.

Sorry if I am mis-reading/seeing something here but to me the wiring you are describing doesn't appear in your pictures. The couple views of your tractor were likely supposed to be the wiring, I am guessing. The pulley in the first picture looks like the old generator pulley, and is larger than I personally would expect to see, or would use, on a tractor alternator. Generally a smaller diameter is used to get the rpm of the alternator up without having to throttle the engine way up. The back of the first alternator you show looks like a Delco CS 130 type, was that the original? Is it the same alternator as in the picture with the pulley? Did you try taking the original one to your local parts store and having them match it up? Have you checked the wires for continuity? A broken/disconnected wire could cause a no charge condition.

The white wire goes to 12v battery.

The black is for 12v ignition.

The rusty one with the big pulley is the original CS130 style. The parts people couldn't read the part number due to the age and scratches on it.

The shiny new one is the 10si which I was trying to get as a 1 wire hookup and didn't work.

The question was the first one, not the 10SI. I'm not saying buy from eBay, but it can be a source to find some info and a starting point. Look at the one on eBay in this link, it looks like what you are describing for clocking. They list vehicles it is supposed to fit, so you can see if the parts people you deal with will check some of these vehicles for you.
