CaptBob 0 #1 Posted August 15, 2009 Battery on my 79 Wheel Horse C-141 (with Kohler 321 engine) would not charge because the regulator rectifier (Toro part #101450) was fried. I picked up a aftermarket replacement on Ebay for $39.80 shipped. It's made in China, works like a champ, and bolts into original holes. Also has a place on the back to mount a separate ground wire if you wish to. Hope this helps.
