Pete, Definitely check the switch on the swivel. When you roll the auger out and hit the rocker switch,the engine will pull down because the master solenoid is being energized at the same time auger "on" solenoid is supposed to be energized if switch on swivel is set correctly. Give it a try and let us know if it don't work. Hyper Harvest II P.S. Yes,you should have 12 volts going through switch.
