I have a Dart DC motor controller, with a POT. speed control.The pot has a travel of about 300 degrees, but uses about 60 degrees, from minimum to maximum speed. The pot is what is supplied with the control from the manufacturer. Specs on the pot are 5K ohms, 2W. if measured from the high side of the pot Ohms are 5k min speed, 3.5k maximum speed. So an idea to expand the range of travel, is to take a multi contact switch, (the old speed control) and add a string of resistors, first being 3.5k, next .5k, then .5, the last .5K in total 5k.
Leave the wire wound pot in place and just leave the wiper at the 0 point. The multi switch would be in series of the wiper, can I just use 1/8w resistors to do this.
