So I was plowing snow today and when I put the tractor back in the shed it wouldn't shut off unless I popped the spark plug wire off. It's been acting weird, sometimes when I shut the switch off it would take a little bit to actually shut off. So should I get a new switch and where can I get one?

^{The switch on it should be a fairly simple to ground type, meaning when you turn it off it shorts out the coil.  I'd try getting some electrical parts cleaner and spray it in the key hole and then work the key back and forth. Most times it just corroded and needs some cleaning.}

also, check to make sure the switch is making good contact to the dash and the ground strap on the back of the switch and the riveted connections are all ok.

If it has a Tecumseh with solid state ignition, you must make sure you get the correct switch. Wrong switch and you send 12V to ignition module and Poof! There goes $150!

These use a ground system, When you turn switch off, switch grounds out the module through the M pole.

I had one just fall part on me, thankfully my son smelled the burning and shut tractor off. The M spade just fell out of switch and was shorting on a hot terminal.

 

here is switch from my ST16, same ignition setup for the Tecumseh's

Thanks for the info guys. I had another switch here for a tecumseh that I tried and it worked good. I'll spray some stuff in thw key hole and see how that works. Maybe I can salvage the switch. If not I'll just get another one.

On my customs I am starting to add solenoids to the starting system when I have them apart for repairs,just too many amps going through the switch which I think is a major cause of their failure.
