Voltage Regulator Rectifier Replacement for Onan P-Series 16HP-20HP B Engine 20 Amp 191-1748 191-2106 191-2208 191-2227 John Deere 318-420 Lawn Tractor

Showed up early. Price is right,works good

Good quality. Perfect fit for my vintage Kohler M8 engine.

Worked great on my Dixie Chopper generac motor.

battery wasn't charging. blown fuse but also found that the rectifier plastic had cracked...didn't rectify anymore. haha. this replacement was a exact fit for a great price. 14+VDC again!! for zero-turn lawn mower.

My Toro tractor had a charge warning light. After pulling the flywheel checking everything and replacing this regulator the light is still on but the battery seems to charge. No idea why the light is on.

The product arrived as advertised. Shipping was a few days late. The packaging was thin and flimsy. The guards were wrapped in thin packaging foam. No packaging on the inside of the box on the ends...there was some damage on the ends of the guards. They were usable...but not nice. They installed fine. The only complaint I have is the screws were not painted. I suspect in a few years I'll have rust running down my gutters from the rusty screw heads.

Installed on a Tecumseh OH-140 engine built in 1973. AC output is similar to P series Onan engines with a 20 amp charging system. Had to cut the case down a bit in order to fit it in the blower shroud, but nothing difficult. Has been working fine for 3 weeks, will update review if it fails.

Replaced a faulty/inop rectifier in the Yamaha gold cart. Very easy job to do. So far its working A-OK.
