I'm thinking one of the mosfets on the control board is shorted out.

I have a ryobi cordless shop vac and the unit will not shut off via the switch. To get it to shut down you have to remove the battery. I pulled the cover and checked the switch with a multimeter and that is operating fine. I unplugged all the wires from the switch and plugged in a battery and the unit still turns on and won't shut off. Has anyone had this issue before? I'm thinking it's a problem with the control board.
