have a Kohler cv 730 in a craftsman gt 5000 tractor , and recently just started blowing fuses ,problem got much worse after I degreased and washed engine , removed stator and it looks ok ??? , it did run for over an hour today , then started blowing fuses again , it reads about 27 volts ac on one of the rectifier ac poles but not the other ??? should it read same on both ac poles ?????? dc pole reads about 13 volts dc ,, I noticed wires at amp meter seem very hot ?? any ideas
sometimes the fuse will blow as soon as you hit start ,other times it will start and run up too 1 or 2 minutes ??

I doubt that the engine is causing the fuse to blow. More likely something in the tractor wiring. Post tractor model numbers, so we can see if a wiring diagram is available. Here is a service manual for your engine so you can test the charging system. https://www.mymowerparts.com/pdf/Ko...d-CV17-CV18-CV20-CV22-CV25-CV22-CV23-CV26.pdf

Craftsman GT 5000 ,, about a month ago it blew 1 fuse ,but since I washed it ,its pretty much constant ,although it did run about a hour today with a 40 amp fuse ,,it calls for a 30 amp

Look under the seat and you’ll find the model number.

Seat switches are generally ground wires and a ground wire shorting to ground usually would not blow a fuse.
