the clutch has likely spun. The little bracket that hangs down either got bent or the clutch bolt is loose allowing the clutch to drop out of mesh with the limiter bracket or the engine is loose. Have seen all 3 instances.
blue from the clutch goes to blue/red in the wire harness. Black from the clutch goes to green/yellow in the wire harness. The long leads from the pto clutch go through a hole and then run up near the starter relay where they connect to the main harness.
Assuming this is a ZG1xx mower? You didn't specify but I kinda recognize the pictures. Always specify what equipment you are working on when posting a question; sure makes things easier.
Many won't read the dvm correctly. That little dash in front of the number can confuzz people. If you do it that way and it reads voltage on g/y make sure it reads positive voltage.Easy to figure out....
put a DVM on the grn/yel wire and ground. Turn on the PTO engage switch. If the meter reads 12 volts....THAT wire is the 'feed' to the coil. Simply connect the other coil wire to GROUND. Pretty sure K use black as the 'ground' colour.
Yessir, the conduit is split plastic sleeving, and I have opened it up and examined the wiring all the way back into and across the back of the gas tank compartment. It all looks pristine. The remnant that is still attached to the chewed-up connector is not long enough to reach more than five or six inches. Of course there could be other pieces of the wire that got cut off during the mangling and are laying out on the lawn somewhere, so the length of the remnant is not definitive.Have you tried to get the wiring harness opened up to see if the other wire broke off inside the bundle? Is it taped together or is there a plastic sleeve? The plastic sleeves are usually split sleeping or cut into pieces so that the wires can exit when they need to.
