My 2008 Brute 4x4 actuator isn't working. I pulled it, cleaned it all up, hooked up to direct power source and it works fine. When checking teh Harness going into the Actuator control unit (according to the manual), I'm only getting 4.6V to the wires that control the actuator, manual says I should get battery voltage at that point? My question is where do I turn from here? I'm no mechanic.... I think it has to be a bad contact to be losing the voltage.... Please advise.
