Curtis Sno-Pro 3000 issues

    I recently purchased a used Curtis Sno-pro 3000 plow used, it is a 2006 model, 7 1/2'. When I went to install it on my truck I realized the previous owner mangled the wiring harness. I ordered a new harness, truck and plow side and installed it, unfortunately it is the new style harness with relays inline instead and not the old style. When I hook onto the plow and hit a button on the controller, the plow motor comes on and will not shut off until I turn the controller off. The plow does not move at all, no lift, no right or left. Motor just runs until I shut it off. I've double checked all my connections. I tried a friends controller with the same outcome. Does anyone on here have any idea where I should look to resolve this problem?

    Since the solenoid feeds current to the plow motor, it may be sticking on. Disconnect the battery cable to the plow. Using a test light operate the plow control and check the solenoid and see if both large terminals are hot after pushing the up button. Then check the small terminal, if its hot, remove the small wire and see if its still hot, if it is, possible bad controller. If not, possible bad solenoid. Make shur the solenoid has a good ground as it grounds thru its base.
