Now that I'm feeling better and the house smoke damage, Escalade, driveway, chiropractor has me fixed up, all the other things and dad's truck is almost done, it's time to get back to concentrating on some Wheel Horse parts lol. :rolling

I have some part samples on the way to be able to stock individual parts, and build a 9 pin wiring harness for the Onan engines. Will keep everyone updated. :thumb1

Good to hear you are on the mend.

That 9 pin connector is one of the weaknesses of the 520H. A replacement harness will be a great addition to the store.

Thanks,

Kurt

You can lead a horse to water but you can't make him drink.
I can't see the forest for the trees.

The part samples are here and are an exact match. The tractor had TE Connectivity/Amp brand parts from Toro, these are actual Molex brand parts. I also have my electronics company quoting me on assembling the harness for each side, I should know what cost that is in a few days and decide if they will build them or I will. :thumb1

I've never assembled one of these connectors. Looks a little tricky to do it right.

I was just next door looking at my neighbor's 1997 520H. Someone replaced the 9 pin Molex with hooded 1/4" spade terminals. One is badly burned. He needs your 9 pins. I'll see if I can talk him into one, once you have then available.

One wire at a time would make it easy and the right crimpers also help, mine do the wire and casing at the same time (2 different size crimps in the same jaw) and are designed for the factory fold type crimp but other methods work also. I put some pics of the fuse block terminals and crimps below, these are the same crimp design only with bullets on the ends. If the wires have been cut up a schematic would be in order for future troubleshooting, but putting them wherever, also 1 at a time would work for the sole disconnect purpose lol. :tounge2

If you need anything at all you know where to find me. :thumb1

I've got to check out your crimpers. I have several for the common crimp terminals, but not for these.

Fingers crossed for the 9 pin Molex.

Thanks Geno,
