The electric PTO on my John Deere 318 was cutting out constantly. After some good suggestions from this forum I checked the PTO plate gap, cleaned the plates, and checked voltage going to pto (measured 12 volts). After this I tried testing and the engine started cutting out on me then it finally quit running. I can start it with the brake on but a soon as I try to lift my foot of the brake it stops running. So I thought it must be the safety switch under the seat so I by passed it with a piece of wire but that didn't help. I checked to see if I'm getting voltage to the seat safety switch under the seat and I am. So the only thing I can think of is that there is a loose wire or broken wire on the return that isn't allowing the seat safety system to complete the electrical loop.
Does this sound like correct thinking? If so, any thoughts on tracing the wire back to the mess of wires behind the dashboard?
Frustrated in WNY.
