        I'd take a look at the motor capacitors. In this hot weather they can do some funny things. I'm sure that you checked the pins on the C-1 machine harnness. I know you said that you changed the motor start relay, but I'd try another one from a working motor. Have had a brand new one not work. Opened it up and the contacts were not closed.

            Humming is usually the start windings not engaging. It could be that the cent switch is stuck in the cut-off position but I would look first at the capacitors. If you have a long enough cable or a jumper (which is a nice diagnostic tool to have), hook your table cable to the sweep motor and see if it runs when you pull TA out. If you have any sort of solid state start switch or potential relay that could be a culprit as well.
