I believe I havevthis wired correctly, the 104 side w orks fine with 120 v from 4 on the 104 and 120 v on two from the 106. When I turn the 106 on I get 120v from 4(common) on the 104 and 2 ( red low speed) and black line 2 high speed on 3 of the 106 resulting in the motor reset kicking out. The motor works fine when wired directly to either white and black or white and red. I'm banging my head against the wall!
The black,red, and white on the left are from the motor, L1 black, L 2 white and A red. The white on the left bottom is 110 common (line) and the black 110 line.
The wire nut extends the common wire from the motor and is not connected to the white from the 110 feed though it may appear that way from the picture angle.
