I have a Craftsman ctx9000 lawn tractor (Murray 107.250040 (2691085-00) - Craftsman CTX9000) with a Murray 40G777-0131-G5 ENGINE, 20HP Briggs & Stratton (Engine Model: 40G777-0131-G5).
Two wires that go to the deck lift motor managed to migrate into an area where they were chafed and then shorted out. This ended up blowing a fuse up in the battery area. I fixed the wires and still blowing fuses. I disconnected every thing in the back end of the tractor and still fuse blew as soon as the key was turned. I removed the seat deck so I could do a thorough inspection and found no melted wires etc.
I moved to the front of the tractor with a plan to disconnect one thing at a time staring with the headlight switch and fuse did not blow. So I checked the wires to ground, a blue wire with red stripe had connectivity to ground so did a grey wire. I figured the blue wire was probably a hot wire and should not have ground? Followed the blue wire in the harness and found it is tapped to a yellow wire and red wire with white stripe. I traced the red/white wire up to the key switch so I disconnected the switch and found the red/white wire also has ground. I found another connector with red/white connecting to a plug going to the motor I disconnected that and the blue/red at the light switch and the red/white at the key no longer had ground. So I am guessing that I have a short in the electrical system on the motor itself.
My question is do my assumptions seem correct? And how do I start troubleshooting shorts on the motor? Are there components that would be the most suspect?
