Hi, new to the forum and tractor ownership. Picked up a Satoh S650G a few weeks ago and have been working on getting it back into good running shape. Current issue I am fiddling with is the charging system. With the old mechanical regulator it puts out over 16 volts. Not wanting to cook my new battery I bought a new voltage regulator (IM-952). Went to install it yesterday and also replaced the terminals and connector housing for the alternator end since it was crumbling.
With the new regulator it won't charge at all and the charge light comes on and stays on. Swapped the old regulator back in and the charge light goes out once the engine is running but still puts out over 16 volts.
I have checked the wiring between the alternator and the voltage regulator and it checks out with 0 or very slightly above 0 ohms. Checked the battery ground and battery positive as well and found no issues.
Took the alternator over to Autozone and while the bearings sound like they are starting to go out the guy was able to get it to charge at 14 volts no problem.
From my research it appears that technically the replacement regulator should actually be the IM-951, though when I talked to the shop I bought the IM-952 from they said the only difference they could really see was the IM-951 has an extra bullet connector coming off the connector and either should really work.
I'm pretty good at a lot of this stuff but dealing with old style charging systems is not my strong point yet. What else could be causing the issues? I opened up and cleaned the old regulator already as well.
