The tractor is an Oliver 660 that is 12-volt negative ground with a generator and a regulator.
A week ago, I ran the tractor, and everything seemed to be working fine, the amp gauge showed about 10 amps of charge. I tried to start the tractor today and the battery was completely dead. I think I may have left the key in the accessory position, but I am not positive. I charged the battery for about 2 hours and the tractor started quickly. The amp gauge did not show any charge, so I started looking for issues. I found that a wire from the regulator to the generator had burnt in half. I replaced the wire with an inline fuse (see pictures) and as soon as I touched the post on the generator the 20 amp fuse blew. I pulled the cover from the regulator and found that the points on the right side were welded. (see pictures). I cleaned both sets of points with 600 grit emery, replaced the fuse and started the tractor but amp gauge was on zero.
What testing should I perform?
Would it help if I polarized the regulator, and if yes, how is that done?
Is the regulator shot?
Is the generator shot?
I was hoping to keep the charging system original, but if regulator or generator are likely bad, I have a mini Denzo alternator I can install.
Thanks
