I have a few calls out to try and find a loaner now. No luck yet.
Is there a way to use a volt meter on a controller to tell if its bad? Controller powers up and even goes into float mode as it should.
Also, I have checked all connections on the harness including all the pins to each connector and relays. Nothing seems to be abnormal.
So after messing with this thing for a couple more hours... The 2 large pins in the connector at the bumper had gotten squeezed together and didn't make a perfect connection. However, now when the plow controller is turned on the plow doesn't move erratically but the controllers red light flashes quickly as if asking for a password. Only owner of this plow and never set a passcode, not sure if this could also have another meaning/cause.
