    It may be the isolation module but that's hard to test. It sounds to me like a bad connection between the plow and vehicle. Remember that the presence of the plow is what makes the isolation module switch and is also what enables the controller. On the old relay systems the ground for the relays had to go through one of the plugs to the plow and then complete the circuit to ground via the main motor cable ground back to the battery negative. The new iso module must do the same thing so check the plugs and the motor connections.
