Thanks Greg. I'm using 115V for the motor. On the motor (peckerhead) I got there are numbers 1 and 4 stamped next to the tabs that the yellow and blue wires attach to. I tried several different ways to wire it, but the one that I tried before posting my question was similar to your first drawing, but I had the blue & yellow where you had L1 & L2 and I had L1 & L2 tied to the center posts and jumpered from there back to the 2 threaded lugs on motor. That seems to be very similar to the 2nd drawing you posted. However, I am confused by the 2 arrows by L1 & L2 and am wondering where they are going. Are they tied to the center posts (like I tried) and then going back to the motor? It seems so and that's what I did and seemed to be why I got the hum when I had the dpdt switch in the OFF position. My next iteration was to tie the white wire to one center post on the switch and then bring that back to the motor while the black wire just goes to the other center post. I was thinking that would provide the break/disconnect needed to prevent the motor hum when the switch was OFF. I haven't tried that, but that was going to be my next attempt.
