So my John Deere S120 rider was delivered today. It was just a drop off, no signature needed. I look it over and everything looks good, the delivery guy did leave the bypass valve control rod pulled out/disengaged from when he pushed it out of truck and onto driveway without pushing it back in, but whatev. Go to start it... won't start. Try again... won't start. This is when we realized the rod hadn't been pushed back in, so we pushed it back in and tried again... won't start. At this point I'm thinking maybe I flooded the engine with all the start attempts with the choke, so I let it sit for half hour. Go back out... won't start. It was getting a spark and trying, it just wasn't kicking over. At this point I'm kind of freaking out, went back out and had a couple neighbor buddies with me... won't start. We take a closer look at everything, and one of them notices a pair of wires, one black and one gray joined by a white plastic plug, that was just dangling. It was near a black plug-in unit, so I see if it plugs in there, and it fits. I go to start it, and it works.
So thankfully he saw that and it worked, it must have come unplugged on the truck maybe when out for delivery, or maybe it was never plugged in. But none of us really knew what the plug in was for, he thought it was maybe for the fuel pump, but none of us really know.
I've been trying to look it up but can't find anything specific. Any small engine guys out there maybe know what that plug in is for?
