Constant power to fuel solenoid problem

[Lawnmasters]

We have an F2260 mower that we done a complete engine out rebuild on. Upon putting it back together, we plugged in the harness to the fuel solenoid and the solenoid click, then went up in smoke. Even with the key off, there is power to the solenoid, even with the ignition switch unplugged from the harness, there is still power to the solenoid. We are in the process of tracing the entire harness down looking for a short, but so far everything is clean.

Any ideas?

I would look at the starter connection to see if the wire is on the battery side or the starter side of the solenoid. I have a couple of z482 diesels that use the starter connection to energize the pull side of the solenoid and the wire from the switch is the hold connection. If the solenoid is a 3 wire solenoid. yours is probably supposed to be wired the same.

I agree,solenoid pulls when engine cranked,then key holds solenoid on other wire. Third wire i believe is ground. So if pull was wired to battery terminal on starter, it would smoke after a few minutes as it draws a lot of amps.
