Blowing fuse turning key
 

I have a LT1050 and while cutting(literally the last row) it died. I saw the fuse blew and every time I put a new one in, it blows as soon as I turn the key. I have checked all connectors visually and seem ok. I have checked the ground and looks to be ok. Any suggestions would be greatly appreciated! I’m not great with diagnosing shorts with meter. I Have taken the deck off unplugged the PTO, and any other plugs individually and it still blows instantly! New battery also.

Could be a short in the keyswitch or harness. Not knowing your particular tractor. Is the back of the keyswitch screws on wire connectors or a plug?

The key switch is plug in.

Unplug headlight circuit. Also do you have anti backfire solenoid on bottom of carb? Both energized from same circuit of kys.

Not sure about the solenoid but i will try to unplug from the headlights and try and also look on the bottom of the carb.

I'd look for rubbed wires. Solenoids and lights seldom blow fuses. It's rare.

You need to know what year tractor you have, then you can get a copy of the wiring diagram here:

I worked on 1 similar to yours and found a bad headlight bulb that the filament had blown and was touching the base of the bulb making a short and blowing the fuse

I've seen that before also, and is possible. But it doesn't happen often. Definitely something to check.

Were do you find the year of the mower? Now that i think of it my headlights are burnt out so i will check that for sure tomorrow. I tried tracing the wires but didn’t see anything.

Look on the serial number tag. I doubt it's printed on it, but may be. The wiring diagrams have a harness number on them. Or at least the one I downloaded did. Maybe you can find the harness number on yours.
