Customer Question

Have a John Deere F525 with the Kawasaki pa540 engine. I put on a new igniter and got it cranked but only runs with the kill wire to coil unplugged. Yet it kills with switch which could be the fuel solenoid doing that. I have unplugged seat and jumper wires that.brake pedal fully depressed or it won't even start, so that's OK. Don't know where any other safety switches are. Need help

Brake switch and seat switch are all the mower has, other than pto switch. Have you checked both of them and their harness plugs?
Customer: replied 9 months ago.
Checked both every way I could and they work fine

What ever it is will not allow pto clutch to click on either

Mower has two relays and diodes, Without a wiring diagram, not sure which one does what, but relays has schematic on the side. Diodes are just electrical check valves that are open in one direction. Check then or swap the relays for starting place.

Yea I've changed the relays. But I cannot pull a schematic, that's why I'm lost

Check the diodes with ohm meter to see if current only goes ome way.

Only see looks like 2 diodes going into relay and I'll have to cut the plastic tubes off them to check. This thing fires on the plug wire tester when I turn ignition switch loose

If I could get the PTO to energize ID know what problem is but there is no ground going through it to make that happen with the problem I have. This thing is the worst I've ever seen with this igniter to crank kawasaki
Customer: replied 9 months ago.
Everything is working except for this kill wire and pto
Customer: replied 9 months ago.
I need a schematic to fix this thing
