Greg,
Since the tablesaw motor works in the shaper connector and position, at least you know that your motor is good. ?Since you have changed out the selector switch and it¡¯s doing the same thing, you probably are good there as well. ?I¡¯m not familiar with the 731, but does it have some sort of limit switch just for the table saw? ?For instance, on my c3-31, there is a limit switch on the panel to access the shaper motor and a limit switch that makes sure the jointer table is locked down or that the dust hood in the planer setup is engaged and not exposing the rotating planer head. ?It could be that one of your limit switches is bad and not letting the saw engage. ?Do you have a wiring diagram that you can share?
