I know we are a car forum... I hope somebody over here can help me out...

I've had some very strange issues with a customers mower. Here's some info Its a john deere lx279 with a liquid cooled 17Hp Kawasaki twin cylinder engine. About 2 years ago he was having starter issues the starter tested bad. I replaced the starter. Every 8-10 times you'd go to start it you'd get a partial engagement of the Bendix so it would hang up.... No problem. We've left it alone. Its very tough to trouble shoot an intermittent part. It was here about a week ago for other maintenance and I was warming it up, I went to drive it around and it got on the seat pressed full forward.... about 15 feet later it completely went dead like the key was turned off. No warning, or anything. It won't crank, it won't make any noises, the battery has 13 volts. And I noticed it popped a fuse. I replaced that fuse. It popped immediately again as soon as the key was turned on.... We did some trouble shooting and found the ignition control module to be the culprit. I replaced that this morning. It has the exact same symptoms as before. As soon as you turn the key to on it pops the fuse. Please help me to get this issue sorted out. Thanks
 
Did you check the cutoff switch that is located under the seat? I've had those go bad, where the mower would not start, due to a short in the switch. Try bypassing the switch with a jumper wire. If the problem goes away, that is the problem.
 
We found the problem. The fuel solenoid on the carb has 12 volts going to it when the key is turned on. That wire was pinched under a valve cover bolt, and worn bare causing the dead short. Once we found that all was well. Thanks for your help.

Hello! Sounds like the safety seat switch is shorted.Bypass it with a jumper that will trick it into thinking the real switch is engaged.
