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.

If the wires go to the same place as the schematic, colors may have just been mistakenly reversed. I have done some rockers from the old Breckwells just match the switch part numbers and a tad pricey.
 
The wires go where the colors say they go. The pin location doesn't match. I bought this used so who knows what kind of chicken tracks are there. So far all the wires off the terminal block are right. The rocker is a 7107 C&K switch. Mom-off-on. I guess I'll get the switch and see if the timer circuit will work. The cool down circuit works. Tested with a fire outside. Just the auger won't turn when it's supposed to. The motor is good. Put a suicide connection on it. It spins. Bypassed the manual position on the switch and it spins. I'll get the timer chips, triacs and relays. Do a global switch out.
 
I would recommend new caps also. Cool let us know how you make out
