No, create an account now. In some applications it may be bolts instead.
One wire will be the top, or further from the starter, another will be the bottom, or closest, and the last one will be a wire pigtail that can only connect in one place. I turned the crank to see if maybe the starter was locked up If you just installed an entire plow set up, I would hope you know how to wire, or find a wiring diagram, for that selenoid. Never jack a vehicle up on grass, dirt or gravel. With a model we can pull up parts schematics along with wiring diagrams etc. Could it have messed up some of the starter wiring as well?
