I just recently bought a used warn m8000 it worked when i plugged it in the first time now that I have it home it wont do anything. The connections are kinda rusty I cleaned them as good as I could, still nothing! I took the main motor wires and hooked them to the battery and all i get is sparks. I guess I will just take it in to the local alternator shop and hope he can fix it. I dont know what else to do, or how to check the silenoids.
