I have a 2016 John Deere Z960M with the Kawasaki FX921V. I was curious why my plugs were wet when I changed the plugs a few days ago. I haven't started it for a few weeks and decided it was time to change the plugs for next year. Occasionally I get a good puff of white smoke when I start it, but not too often. Then I got to thinking, I wonder if that fuel shutoff solenoid is stuck open or something. I thought it would be really simple. Turn the key on (parking brake on, but nobody on the seat) and there would be power to that solenoid and I'd probably even hear it click or feel it click if my fingers were on it. No...no click and no power on the green wire going to it. I checked the wire with an ohm meter where it goes up and over the engine and connects to that wiring harness on the left side (sort of hangs freely there just to the left of the engine). The wire is good. I also thought maybe someone needs to be on the seat for the solenoid to get power (parking brake on, person on seat, key in run position). No luck. Still no power there at the harness for that wire and of course no power at the connector that plugs into the solenoid. For the life of me, I can't figure out why I can't get power/12V there on that green wire even at the harness to the left of the engine. Fuse is fine and the engine runs fine other than the occasional white puff of smoke at startup and of course I think that's related to the wet plugs/fuel entering the cylinders for a brief second or two when I turn off the engine. Any ideas? It's under warranty so ultimately it's not a big deal, but I'd rather not have to mess with the dealer for something simple like this if I don't have to or even if I do, I'd like to know for sure what the issue is before I called them.
