I would suggest grounding pin 3 and connecting a 12V source to pins 4, 1, 5, 7 and 6 in sequential order. We go through the possibilities because surely it wasn't the resistor pack, that was just replaced... it could be a bad connection, bad relay, bad switch, blown fuse...etc. There is a little panel you can remove. After removing the bench and swivel there's nothing there?? Be sure to check for the 12V with a separate ground, not the other side of the motor. That is unless the problem occurs again and again with increasing frequency. The way the resistor pack does this is by shortening or lengthening the circuit through the coils to add or subtract the amount of resistance it takes to get the speed you want. I replaced it 3X and was starting to think like you but did not know what that part was. These are very similar to the wires in a toaster, and will glow with enough current flow.
