I have a dremel scroll saw with a dc motor and a broken speed control. I
assume it is some kind of pot. There are 3 wires going to the terminals on
the pot. If i connect all 3 the motor sometimes makes 1/2 turn but usually
just hums. I traced the 3 wires back to a connector on the pcb power supply
board. Do I need a minimum resistance to make this work. I'd be happy to
just bypass the switch and run at full speed.
Thanks
