Question on 1920 Buick 6 cyl wiring

My National Service Data show a large circular device that has a circuit breaker as part of it and two sets of lobes that may indicate a switch with two levers. Sorry I can't be more specific, but the device is not identified as anything, but there are wires coming from it to other parts of the car, so here goes.... The terminal identified a 1 goes to the coil primary and is also attached to shunt field of the generator side of the motor generator. This is the third brush circuit on the generator. Hope this is clear enough.

Charley,

My diagram for your car shows only one wire hooked to the #1 terminal on the switch. That wire goes to the ignition coil where it junctions with the "F" / Field wire from the starter / generator. The terminal I am referring to on your ignition coil should/might be labeled "BAT". Hope this helps. Feel free to call or email with any other questions.
