This Wurlitzer 2200 is not making selections.
The selector buttons press and stay down and the reset button works when just one button has been pressed, but when the second button is pressed nothing happens.
If I manually activate a pin on the pin bank then the jukebox operates as it should - finds record, plays and cancels.
I guess the fault would be in the stepper unit, where all the wires connect, but the manual is very vague as to the order of operation.
Any suggestions would be welcome.

Keith,
On those, that problem is usually one, or more, of (the many) leaf switches, on the keyboard. that are supposed to be closed, when two buttons are "down", is staying open. If not there--plug(s), relays--are failing. see schematics--
