Kubota B7800
Need assistance please. Tractor would not start and did all the general electrical checks and found that the fuel shut off selonid was not working. When I pushed the "plunger" in the tractor started, however I had to manually pull the plunger out to get it stopped. Item replaced with new and now tractor will not start at all

In dire need of electrical wiring diagram

Dealer cannot supply and unfortunately they have no idea what is wrong, they just want to sell me a new tractor. This tractor has 500 miles on it. Live in Mo and have had 21 inches of rain in 8 days. Cutting 5 acres of grass.

Hmmmm.... Can't think of anyone on here that has a B7800. I'm sure there are plenty. Someone will chime in with assistance. I always look for simple problems. If the shutoff solenoid was the problem the first time. Then I wouldn't start looking elsewhere now. I'd focus on it and everything you touched in the process of replacing it. I'd also run a test on the solenoid to be sure it is functional, might have gotten a bad one. That testing would educate me as to whether I need "power" to the solenoid to start the engine, and turn power off to that connector to get it to shutdown?? I'm assuming that's how it works. That's normal behavior.

For clarity in this discussion, describe what you mean by "not start at all". Are you saying the engine turns over but does not fire up and idle?? Or are you saying it fails to turn over??
