Oops. I see from you original post that the score motor stops.
Try this. Remove the ball (so it doesn't crash down on your plastics).
Start a game.
Raise the PF to the upright position.
Find the O relay (ball return relay) on the bottom board.
Manually actuate it.
Does the score motor turn and the outhole coil fire?
I bet it will...
Next...
We've proven that the outhole coil (curiosly called the ball return coil in this game) is good.
But, the ball return relay isn't firing.
First let's verify that the ball return relay coil is good.
You need a jumper wire, about 3 feet long, preferably with alligator clips on both ends.
Clip one end of your jumper to the solder lug on the bounce switch (located on the bottom board) that has a red-white wire soldered to it. This is always a good place to pick up the "hot" side of power.
Briefly touch the coil lug of the O relay that has a yellow-black wire soldered to it with the other end of your jumper wire.
The coil should fire. If not, it's dead.
Assuming it did...
Find the normally open switch on the O relay that has maroon-green and and white-orange wires leading to it.
Briefly touch the loose jumper wire end to the white-orange lug.
The coil should fire.
If not, examine the NC switches on Q (yellow-black and slate-black) and on AX (slate-black and white-orange). One of these normally closed switches isn't making.
If the coil does fire...
Touch the loose jumper to the brown-white wire on the outhole switch.
If the coil doesn't fire, examine the make/break switch on A with center wire brown-white and flanking wires of white-orange and green-white. It should be making on the white-orange side.
Make sense?
Have you been able to follow along with the schematics?
