This is the schematic that fell out of the back panel of the unit. After many hours of digesting the diagram, I was able to filter out all the junk I didn't need (like almost all of it). I originally just wanted to hack the original controls, but instead I'm just straight bypassing them and controlling the motor directly with the Raspberry Pi and SSRs.

SchematicAutoMashTun.pdf

A rough schematic of the motor control scheme. The simplest method possible in order to achieve forward/reverse and high/low modes of the motor. The motor is a single phase synchronous induction motor. The Raspberry Pi will signal the appropriate relays to toggle on/off to power up the correct windings. The motor has an integrated centrifugal switch that automatically handles the start capacitor.
