MAIN DRIVER OFF means that the controller has failed in it's ability to turn on the solenoid. I've seen this happen a few times where the coil suppression diode on the solenoid (if equipped) fails and creates a direct short between the positive and negative posts of the solenoid. This will damage the solenoid driver in the controller and if you install a new controller without changing the diode and/or solenoid (if equipped with internal diode) you're going to ruin another controller as well.
