Fisher MM2 Wiring Harness
This weekend I installed the harness for my Fisher MM2 plow. Everything with the light kit went smoothly, but I'm having trouble getting my motor relay to work.
I have a orange black wire and a brown red wire that go to the main terminals. Neither wires are showing 12 volts to through the relay. The orange black is also hooked to the negative battery terminal as the diagram suggests. Now I'm looking at other diagrams and some show a green red wire that is hooked to the positive terminal of the relay, which my harness doesn't have.
So from here I'm not sure what to do. The relay never indicated either post being a dedicated positive or negative, and to my knowledge it shouldn't matter. Any help would be appreciated.
