I have a John Deere LX172 that has an electrical bug that seems like it would be easy to locate by someone with expereince. I inherited this machine when i purchased my property. I pulled the manula, serviced the machine, and began mowing. She ran like a top for about 6 hours of service and suddenly died. Not a sputter death, an instant death. I thought it was a bateery issue but the batt was brand new and tested great. I sniffed around and found a blown 15 amp fuse behind the dash. Replaced it and the mower starts up and runs like a top. However, when you engage a gear or cycle the PTO switch, the motor instantly dies. I have been searching high and low for a wiring diagram to try and trouble shoot this but cant find one.
Anyone have any idea? My first guess was the relay was bad behind the pto, but that wouldnt affect the gear box circuit right?
Are there any other fuses in this bad boy I am missing?
I killed the motor, turned the key on and the switch below the carb gets power, throw the PTO or the Gear and the power to the switch dies.
