Quoted from Gnrwarkfc:How do I look at the score motor on my machine.
At rest, the "A" stack actuator is in the notch in the cam. Or count the switches. Or post a picture here.

Quoted from Gnrwarkfc:Any ways can anyone look at the schematic and see Whitehall switch controls the motor running?
These are the switches that run the motor.

On a single relay they should all change state together. But you can identify which switch the schematic is referring to by checking the connected wire colors.

Quoted from Gnrwarkfc:What does change state together mean?
Almost all relays have more than one switch. All switches on a single relay should change from open to closed (or from closed to open) together.
For a switch to work 3 things are necessary:
1) When open, there should be a small space between the contact points (duh)
2) When closing, the long blade's contact point should push the short blade's contact point enough to move the short blade
3) The contact points should be clean, which they usually will be if #2 is happening

Quoted from Gnrwarkfc:the motor runs but it doesn’t stop.
Which of these switches is keeping it running?
