1811 blowing fuse
 

So I picked up an 1811 about a month ago and everything worked good when I got it but then a couple of snows ago I went to run the snowthrower and when I turned on the PTO switch it blew the fuse. I replaced the key switch and the PTO switch and it still is blowing it. PTO works with a jumper wire and rocker switch I made up for temporary use. Has anyone else had this problem before? I know wiring and can do wiring, just curious to see if it might be something simple so I'm not chasing wires cause everybody knows that's super fun. Thanks in advance

Sounds like you have a shorted wire (Black) from the "B" Terminal on the PTO switch to the PTO Molex Plug. Take a DVM and trace it down and fix the short.

You could also disconnect the connector going to the coil on the PTO clutch, measure what to get for resistance across the leads, THEN measure the leads - one at a time to ground. I had a 782 that was doing the same thing once. I found 1 lead that practically had 0 zero ohms to ground while the other lead had a resistance of the coil winding to ground. Since I had a driveway to clear snow from, I needed to get it running if possible. I ended up swapping the positions of the PTO coil wires in the connector. I figured if one wire gets 12V and the other gets ground, I might as well connect it so ground gets applied to the grounded wire and 12V to the other. If it worked (and it did), I was able to run it clear the drive and replace it once it came in.

Well I was just outside messing with it and I found two things, a previous owner had hard wired the seat switch and bare terminals were touching the battery box so I taped them for now and the other was that the terminals on the reverse relay were pretty cruddy so I cleaned them up and i put in a new fuse turned the key on hit the PTO switch and it didn't blow the fuse.:biggrin2: But thank you for the possible solutions

Sounds like you solved your problem, all you need is snow...

My old boss said that 1/2 the problems could be fixed with your eyes. I've found that to be true.

That's what Ray said....
