Toro Z Master No Start/No PTO problem

I have a 2007 vintage Toro Z Master 60" mower, had it about 4 years, bought it with 2000 hours. Replace the engine last year with a new Kawasaki, new PTO clutch, new belts, spindles, etc. Ran great, not an issue at all. Today, I was running it in some thicker stuff, something must have hooked the wires that go to the electric clutch and pulled the wires down and into the deck belt. The mower stopped. I found the wires, wrapped them up as best I could, sorted out what had happened and tried to start it up. Nothing. Looked around and found nothing out of the ordinary, but I also had no relay click or solenoid click. Check the fuses and someone replaced all three with 40 Amp maxi's. One was blown, replaced it and I got my click from the relays, but no start. No crank, no start, nothing. Tried jumping it from the battery, nothing. Jumped the solenoid terminals and she cranked. Turned on the key, jumped the solenoid, started right up. Pulled the PTO button, nothing. Not a thing. Soooooo.....I drove it back to the barn and looked around and established the following. 1) Battery is fully charged. 2) When it is running, it is charging. 3) Both relays that are switched by the handles, click when you move the handle bars. 4) Replaced the solenoid (because I had an extra laying around), no change. 5) PTO clutch, when by-passed, engages and disengages when touched to 12 volts, so it still works. 6) Pulling the PTO button does nothing.

Please help in any way.....

Re: Toro Z Master No Start/No PTO problem

I have no idea how things are laid out on this, but is it possible the connector got jerked/dislodged from the PTO switch?

Re: Toro Z Master No Start/No PTO problem

Yeah, follow the pto wires to see where they connect to is still connected right, and that there are no breaks in the insulation along the way.

You might consider buying/remaking at least part of the wiring harness, because the wires got caught in the belts, so they would have been pulled on pretty hard, so the wires could be damaged anywhere inside the insulation, or where the wires go into connectors, or the connectors themselves, as no part of the wiring harness is designed to keep working right after being yanked on. I wouldn't be surprised if you continue to have intermittent electrical problems until you replace all the wires that got pulled on (not just the pto wires, but whatever wires/connectors that get pulled on when you pull on the pto wires as well), even after you fix this immediate problem.
