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.
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.
I picked up a wheel horse and I am having trouble finding the connection for this wire. I have no spark and have searched for the placement of this wire within the distance of its length...any ideas?...can't seem to paste the picture....

The Engine won't crank.
I know my voltage regulator is bad on my Onan P220 and was wondering if anyone has an opinion on a replacement, OEM or aftermarket?
Also, I checked my stator leads for AC Voltage and got about 25 volts at 3600 rpm on each. Is this OK? I know it says in the 40’s.
