LS MT125
Any one else have this problem with this brand tractor (and have a solution). The F3 fuse blows when the ignition switch is turned on. Originally the F3 fuse blew out while in operation, using the loader. I’ve checked the safety switches for connectivity, which seem good. Thanks for your ideas and input.

If it's blowing the fuse, there is a short somewhere.

You'll need to figure out what circuit that is, trace the wires and see which one may be damaged.

Thank you PTSG. An excellent local technician did exactly that. He found two wires from the alternator rubbing on the engine block. Repaired the wires and now the tractor is working (not blowing out fuses).

That'll do it. A fairly easy fix, albeit, stuff like this can often be very hard to find.

Thanks for the update.
