Anyone have creative ideas / designs for building an economical generator for 520 tractor? I have always wanted one and contemplated building one a time or two before. I have only found a few used models over the last 20 years. Recently saw a new old stock unit on a tractor on Instagram. It was pretty awesome!

Hello everyone! I am going to replace the ignition trigger on my grandfather's 520. Any tips, tricks or important things I should know before starting? I already have the parts. I just need to tear into it.
I didn't know Cummins owned Onan.

I read through a few related posts but my symptoms sound different.
Have an '89-'90? Wheelhorse 520-H, model 4120OE01.
When I engage the PTO, the engine stalls. No fault indicators.
However, everything else seems normal:
- all lights work when pressing 'TEST'
- when I engage the PTO without sitting on the seat, the engine also stalls, but the 'SEAT' light comes on. Normal.
- when I try to start the engine with the PTO engaged, it won't start and 'PTO' lights up. Normal.
- after disconnecting the load (2-stage snow blower belt in this case) from the PTO, I get the same problem, engine stalls immediately. PTO pulley turns along fine with the remaining motion.
And I also need to mention: the first time it happened it was intermittent. The tractor and snowblower attachment were used over a month ago, without any problem.This time got above symptom upon startup. I didn't feel like shoveling so after revving the engine for a minute or two and a few 'encouraging' words, it worked. I switched the PTO off and on several times afterwards with no problem (engine warm, obviously). Today, with the engine cold, the problem is back.
I think there's enough reason to rule out the PTO- and seat- switches. But what else should I check?
This is my first time writing in the forum and I hope I've given enough clues without boring you.
Any hints and advice are appreciated.
PS any good tricks to counteract the belt tensioner on the 2-stage snow thrower (model 79361)? It is a bear to connect and disconnect.
I'm looking for a oil pressure sensor for a 520-8 at least that's what I was told it was but it might not be that so if someone know what part it is that would be great as I'm still learning I cant seem to find one anywhere if anyone has a extra one or knows were I can get one the info would be greatly appreciated thanks
Started fine 2 weeks ago. I left key in ignition and fear grandson may have turned it slightly to right a week ago.. not enough to engage starter but perhaps enough to drain battery.
Went to start it yesterday and no charge at all. Started charging it and battery began to take charge. However starter turned over but didnt turn engine over.
Question is do I just need more of a charge (more amps) or do I have another problem?
Lol, have 5 inches of snow headed here starting tonight so I need to get ahead of this today.
