I have an older Prescott EXP with the analog board. The manual bypass rocker switch is bad. I can jump it and force the auger motor to turn (jumped LL circuit for testing). It doesn't run on the timer circuit. The plug has the blue wire and black wire different from the schematic. I can order all the components on this board from Mouser for around 30 -40 bucks. What I need to know is if some passed mod has been done so it doesn't match the drawing.
