    Basically, the plow is draining the battery and is not running from the alternator. I have changed the battery in the truck and it is doing the same thing. The plow was still operational but it was dimming the lights and turning off the radio whenever it was lifting or angling. I believe there is a short but I only checked the fuse off of the module?? under the hood and where the red wire connects into the fuse box. It is a 2 year old 8' xblade on a 04 350. Could it be the truck alternator? I can put a different plow on it to test but its a pain because that plow has to be jacked up to fit on the truck.

    It could be the alternator, but it is most likely a connection to the Fisher motor
    solenoid or battery connection. Ford battery terminals are not my favorite. The
    aux power taps could be your problem. The fuses you checked are only for
    control to protect the E-Force box.
    Your radio shuts off because it has "low voltage protection" built in.
    Duel batterys and clean connections [dialectric grease] should solve your

    A couple chevys I've had have done that, couple times a new battery fixed it, once it was the alternator. Have a good shop check it.
