Good morning, I have been a long time reader, but a first time poster.
I have a 1988 Wheel Horse 520HC Tractor. Does not charge, and I have to assume that it is due to the fuse at the front of the engine being blown. However if I replace the fuse that is located at the front of the engine, the wire at the voltage regulator will get hot, start to smoke as it melts the wires insulation.
I have not started testing anything yet, as I just have stumbled upon this issue and was wondering if anyone else has had the same style of problem and what kind of repair did you have to perform.
I need to replace the voltage rectifier on a 520H.
So I ordered the following replacement part: "New Rectifier Regulator for Onan P-Series Alternators 16 17 18 19 20HP Engines 20 Amp Rating 191-1748, 191-2106, 191-2208, 191-2227 by Crank-n-Charge"
This new rectifier has 3 male spade connectors, yet on the tractor I have voltage rectifier with 4 spade connectors. I've attached a picture of the current rectifier.
Can I use this new rectifier and assume I can wire the white and grey wires together?
Or is this currently installed rectifier something special since it has 4 spade connectors and the two wires need to be independent of each other?
Thank you for helping me out.
How do you know which way to plug in the three prong wiring harnes that has two black wires on the out edges with one green wire in the center as it will plug in in either direction. There is no detent on the connector directing how to plug it in - it will go in in either direction. Help 1968 Charger 12 Automatic Wheel Horse firstname.lastname@example.org
