In this video I work on my 520-H Wheelhorse lawn and garden tractor. It has a whole slew of problems. The majority of the video is spent on troubleshooting wiring issues. The tractor had damaged wiring and for several years could only be operated with jumper wires.
It first started late 90's to early 2000's the starting circuit stopped working. To start the tractor it had to be manually energize at the solenoid on the starter. Then the key on ignition stopped functioning. Following along as I step through the starting circuit.
The same process could be applied to other Wheelhorse tractors. I am not an expert in any subject matter, but can logically work through most things. Wiring sometimes evades me....
The video was starting to get too long and the tires did not arrive yet. I will include the motion lever linkage repair and general assembly overview with the tire replacement video.

I've started an attempt at reviving a 520h. It's rough around the edges but hours meter reads less than 300. I tried to start it today and it was not engaging the starter. Turns out the same fuse on mine was melted. I dug out what was left of the melted fuse and popped a new one in. The connector in the fuse board was also at an angle on mine, so I bent the fin on the fuse to fit. Bam. It now turns over. Fuel system needs work, but this video helped me alot today. Thank you!

Excellent! I am glad I could help out. Keep an eye on the fuse block. A poor connection can cause them to heat up. I believe it is a common occurrence. If it continues to give you trouble try switching it out for an inline replacement fuse holder. Thanks for watching! 👍😁

Excellent! Keep an eye on the fuse. Dirty / lose connections can cause it to heat up and melt. Thanks for watching! 👍😁

@@FlatThunder yup mine was very loose but luckily wasn't melted. Ended up taking apart the fuse box and squishing the metal pins together and now the fuse holds in there super tight! Thanks again!

Thanks for the video. Mine stopped working a few years ago and has been sitting in my driveway with a tarp over it ever since. Might get out there this weekend and mess with it.

If high voltage, 17 or 18 vdc, blows fuse...remove the regulator from the chassis and clean the reg / chassis area of rust or paint to re-establish a good chassis ground.
@FlatThunder
@FlatThunder 2 года назад
Good idea! I believe I cleaned the connections at the regulator and the grounds. I can't remember if I removed it completely or not. Thanks for watching 👍😁

I have a few more videos on 520's check them out! They could be helpful in getting your tractor back in action. They are powerful machines. Thanks for watching 👍😁

@@FlatThunder hi man I want to change the fuse block , the entire fuse box , is it easy or do I have to take the whole thing apart ?

@@sinabagherisarvestani8924 I haven't tried it, but I think you can access it by taking the battery out. The wires might be a little short to work with. I think I will replace the one that was giving me troubles on mine in the future. Thanks for watching! 👍😁

I had a similar problem with a Kubota diesel tractor. The inline fuse holder was intermittent.
@FlatThunder
@FlatThunder 3 года назад
It's the inconsistent problems that are difficult to diagnose. First it has a good connection, but loses it under load.... Tricky. Happy you got the Kubota fixed. I like their tractors and equipment. Thanks for watching! 👍😁

Get a Toro Wheel Horse 520H demystifying guide. It will help you with the wiring and location of things.

I found the eight page guide, on red square forum, after I tinkered around with it for awhile. It looks much better than the old images I printed off a Google search. I didn't know it was called the 'demystifying guide' until now. Great reference! Thank you for sharing and thanks for watching! 👍😁

Buenas noches Requiero conseguir kit de ignicion. Cuanto cuesta puesto en coolmbia ? Gracias
@FlatThunder
@FlatThunder 3 года назад
Hola! I am guessing installation would $200-$300 USD for labor. The parts were around $150 USD when I purchased them in 2019. Ballpark guess $350-$450 total from a reputable place. This is for a new ignition pickup / trigger installation. Thanks for watching! 👍 :)

I would have one of these lawnmowers and I can't get any spark out of it is there a way to troubleshoot the ignition or better better question is can you buy the electronica module for this onan engine?
@FlatThunder
@FlatThunder 2 года назад
Put a hot jumper directly from the positive side of the battery to the primary side of the coil. If it starts it is a wiring related issue. If it still does not have spark it is a coil or ignition module fault. Thanks for watching 👍😁

Hey my 520h wheelhorse has a problem when i turn the key to the “Run” position the starter engages automatically and when it starts it doesn’t shut off the starter keeping it running?
@FlatThunder
@FlatThunder Год назад
If you didn't recently change or adjust anything, the ignition wire is shorting to the starter solenoid feed. Disconnect the small wire at the starter solenoid, I think it's blue, and trace the short. The easiest way to repair it is to disconnect the old wire and route a new one to the ignition start terminal at the key switch. Thanks for watching! 👍😁

Weird I thought I already responded, but must have fat fingered the buttons. I think you can replace the block by removing the battery. The wires will be a little short to work with. I plan on replacing the troublesome fuse on mine in the future. Thanks for watching! 👍😁
