My o4 polaris magnum 330 needs a solenoid, got that, but now the old one is off and I can't remember where all the wires go. I have one wire i'm not sure about, it is black, I'm not sure if it is from the starter, or if the handwarmers are connected to the solenoid. I have two red wires connected to the top post on the solenoid, one is from the battery the other I have no Idea, and one red wire is connected to the bottom post on the solenoid. Is the black wire a ground? I don't recall seeing anything on the solenoid that states positive and negative. The guys at the Polaris Dealership said I'd have no problems doing it myself. I have spent hours on the computer looking for information on this simple project and haven't been able to come across any answers.
