  1. 1988 520H not turning over

    I appreciate all of the prompt feedback and advice! I just got in from work, so I'll go take some pics and maybe a video as well, and get those up here soon. In response to some of the advice: I'm going to try power directly to the starter one more time, and see if anything changes.The fuses all look good to the naked eye, and there is continuity in each; however, I may end up getting a few of those next time I head to the parts shop.The battery has not been load tested, yet.How do I manually turn the engine over at the flywheel?Thanks again!
  2. Hoping for some help, advice, anything to make my months-long mission to get my 520-H running a success story. Inherited the tractor from the previous owner of my home. He rarely used it -- preferred his zero-turn -- and advised that I always keep it on the float charger when not in use. I used it for one month's worth of cuts last summer, and then began having problems. At first, the engine was surging. It would fluctuate from high to low rpm with the choke off. However, if I played with the choke (thereby getting way too much fuel and oil into my system), it would run for at least the rest of that cut. After having to keep it running with the choke, it eventually stopped turning over AT ALL. I did the general maintenance: changed both plugs, dropped the oil, drained the fuel, replaced the fuel filter, removed all of the visible (and accessible) electrical connections and cleaned them up. Bought a new battery as well, and the tractor started right up. Sounded better than ever. For one cut. By the end of the cut, I had to start messing with the choke again to keep it running. So, I cleaned the carb, replaced the fuel filter (because it was making a strange knocking sound), cleaned the (new-ish) plugs, bench tested the solenoid, changed the solenoid. When I connected the battery and went to start, I got (what sounded like) very little power to the starter. Loud clicking/rattling sounds ensued, so I brought the batt to Autozone to check the juice. It was at 50%, and it was only one month old. They charged it, and when I reconnected the batt...nada. Nothing. The same old clicking, metal-thrashing-like sound/s. I've tried to jump the solenoid directly -- same result. I've bypassed the solenoid and put all connections directly to the starter -- same result. I've downloaded as many Wheel Horse PDFs as I could find, including the demys guide. Now, I'm thinking about the regulator. Thinking about it as it sits in front of my laptop. It's an Onan 14v 20a. Two ACs and one B+ connections. I'm really hoping it's not the stator and/or the starter. So, any advice on how I should proceed would be greatly appreciated. I have experience with small engines from my years taking apart and racing dirt bikes, but things are just a bit more challenging to access with this beast. But, from EVERYTHING that I have read/heard, a working/running WH will be well worth all of my effort. Sorry for the long post. I am an English teacher : ) -O
