Just a follow up on this since the other thread is closed,
I replaced the alternator on the tractor finally. I ended up using a Delco 7127M-3 with a internal regulator that was not one wire compatable. I did this mainly due to the cheap cost of the unit ($31 from Advance Auto parts refurbished) and the simplicity of wiring it in. These units even come with a wiring diagram that's necessary in the box. It makes it very easy to follow the directions and swap it out. On mine the new alt is much bigger physically than the old one but it still mounts with the main bolt just fine. Same size bolt hole and all. The pulley that is supplied with the alt is ok as well so no swap out was necessary. All I had to do was to make a new bracket for the 2nd bolt hole and what i did was use the old original bracket and the u shaped latch from a latching mech from a barn door (those with barns should know what this is). I used that just because it was laying around and it is very study steel and avoided any part on the alternator. It works good. I did move the mounting point but that was minor. I cut out the regulator (left it on the tractor though) and just wired those two wires together. And at the alternator I put that connection onto the number 2 one and the number one I just put a wire directly to the + terminal and in this case that's the + output from the alternator. Not very complicated at all and last night I was able to run the tractor with all the lights on for the first time ever ! All other times it was draining the battery when I'd cut in the evening. Also with this setup it'll allow me to add some more 50w lights for some real late night working. I'll put a couple more up there so I can really see.
Thanks everyone for your suggestions.
