    I have a nice 19" Edwards clock with what seems to be the standard two motor set up with a schematic for both "networked" and "solo" use (I know those are the wrong terms but, hey I'm a newcomer here!)

    So for solo use, ignore the red wire. Some have suggested to use the rapid advance add a switch between the red and the black wire.

    So here's the question: If I add a momentary switch to power the 2nd motor, do I need to also interrupt/break power to the standard/synchronous motor?

    If it's based on two Telechron motors, it's my experience that the normal timekeeping motor is always energized even when the fast forward motor is turned on. (not sure if Edwards used other motors/movements so YMMV.)

    typically the early Telechron/Edwards/Electric Time/Auth movements had two motors - one is a normal and one is a 10 times advance - also typically 115VAC
