    I have a year old EX90.

    today it, angled hard to the drivers side and kept on trying to angle. The Pump kept on pumping the whole time, and it kept running so hard that you could hear the drain on the truck.

    Only way to stop it was to disconnect the plows power source.

    Any Ideas, I have tho have the polw up and runnig ASAP.

    Well in order for the power unit to continuously run either the motor starter solenoid is stuck or it is recieving power when it is not supposed to. Disconnect the controller, then reconnect the power and see what happens. If the problem dissapears reconnect the controller and try it again. If the problem remains I would look for a problem with the control harness ie: melted wires, chaffed, pinched mashed wires. Something would have to be shorting.
