Here is who is shown on the Prestolite page... not sure if its helpful.

I would call any local alternator repair shops (if you can even find one) to see if they can service what you have.

I found at least one a bit closer to me, looks like there are a few in Portland as well if I really have to go up there

Thank you gents! You are amazing, Ill go see if I can find a sticker on mine.. Not sure I will being early 90's machine, but we shall see!

Well no stickers that I can feel or see, snagged some pictures, I don't think there would be an issue wiring up another 40amp 24v unit as it's nothing super special about these alternators from what I can see.

This is not the proper Alternator for your set anyway. Look at the part number on the Alt. Look at the list I sent. See that number?

I went and looked that up, the number that is easily seen is the voltage regulator part which who knows may be bad.. Lol

I think the next time its nice outside Ill go pull the alternator and actually check it all over. As for right now.. I can get by with just using my battery tender, I have it setup to the slave port, I have a Noco G15000 that does 24v so it works out, also have 2 brand new batterys in there, I know 2x individual 12v chargers are better, but that requires buying new chargers and I have this one already.

@tarster There is always the possibility that your alternator just needs some new diodes. Not generally all that pricey.

Im planning to take it apart when I get it out of the gen set here and see what I can see and test before buying anything.. New ones are dang expensive for what it is..

Finally had some time to get on this, turns out the alternator that was in there was a prestolite so I may just try putting a new control board on it and see what I get.

Picked up a new alternator from a guy on eBay out of England.

Went to take the old unit off and boy.. I think the military got their use out of this belt!

Wow!

 

[Guyfang]

Got to get your moneys worth!

Although not the correct alternator. Is it possible the Belt was the original problem not making enough contact to produce power?

Highly possible, when disconnecting the wires I did see that the exciter stud was really loose, Im still going to put the new one in place and then my plan is to take time looking over the old alternator or maybe have it tested, if it needs a new control board those are only like 20 bucks and should be easy to put in place and then either i have a spare.
