   OUCH ! Man I feel your pain... kinda late now but you should have confirmed you get 30-40 Volts AC from the 2 stator wires....before ordering the reg/rect parts. Since you've got those 'new' parts, why not either get a real good stator or just rewire what you have?
I've rewired stators in the past,it ain't hard to do. Take a couple pictures,remove old wire by COUNTING the number of 'loops' each stator 'post' has on it. They should all be the same..It's just one piece of wire and easy to test. There should be continuity( low resistance) between the two ends.If it's 'open', the wire is busted(easy to fix). The other test is two check between one of the ends and the metal ring, That HAS to be OPEN. If it's not, there's a 'short' and has to be found. The short can be casued by the enamel coating having rubbed off,allowing the bare copper to touch the ring. Again a fairly easy fix,when you find it, just insulate with black tape.
Another option is to find another tractor(any colour) that has same/similar engine. Harvest it's stator,test, and you may get lucky.

If you had room, a CS-130 (late 90s GM) alternator could be a viable option.Lot smaller than those 'big beasties' from the 70s.

rewiring the stator will only take 2 hours...

	Paid $83.00 from Onan Parts for new rectifier #0541-0592 (didn't fix), and then $91.00 next from Onan Parts for new regulator #541-0593 trying fix the no charging problem on my 620 - didn't help, cause the "good used" stator I bought apparently wasn't. These part numbers supercede/replace the old part numbers in the Onan parts manual. Information and pricing is still available from Onan Parts. Is there any interest in either of these? I took them off the tractor, as I am going to mount an external alternator. Still have the box and instructions for the rectifier. Would like to get at least half of what I paid for these if there is any interest. Thanks Edited by macvette - 09 Dec 2016 at 10:18pm
