Kenmore Clothes Dryer motor theory

I have lost the original connection diagram for my Kenmore dryer.  
( Don't ask )
The motor has 3 leads.  ( orange, yellow and black )
If I connect  one side of 120VAC to the orange lead and the other side  
of 120VAC to both the yellow and black leads , the motor starts running.
According to a diagram I have for another Kenmore , either the yellow  
or black lead is disconnected by a switch which is activated by  
rotational inertia ( RI ) from the spinning motor.
Since this RI switch has been worn out, I was going to switch off the  
appropriate lead once once a hall effect device detected shaft  
rotation for 1 second.
What I don't know is how to determine which lead I should switch off.

Black/orange shows 2.7 ohms
Yellow/orange shows 2 ohms

Update:
I have discovered that with AC applied to yellow / orange the motor  
will run if given a hand  powered spin.
Black / orange will NOT run when powered and given a spin move.    
( just buzzes )
So I guess the black lead is to be disconnected once the motor starts  
spinning.
