I tried searching for this on the net, but all of the schematics I've seen are different. I've pieced together what I think is the correct troubleshooting method, but I am stumped now.
Symptom: Pushing replay button with credits on the game will not start a game. It only seems to work about 1 out of 10 times.

I am using the circuit highlighted in Red. Here are all the things I've done:
When jumpering from Red-white on the fuse holder to orange on the replay button, the game does not start when pushing the replay button.
When jumpering from brown on the replay button to (it's slate for some reason, hate these gottlieb wire colors, but I'll call it orange white) the power side of the coil, the credit button started a game 10 out of 10 times.
(I understand using a multimeter isn't the greatest troubleshooting option, but I thought it was ok for switches?)
When measuring continuity from Brown to Slate-Green on the W relay, there is continuity when power is off.
(I have closed the replay unit switch to simulate free play) When checking continuity from slate-green to yellow green on the replay unit zero position switch, there is continuity.
I then cleaned and adjusted the switch on the tilt relay, and when closing that switch from yellow-green to orange-white (remember it's slate again), there is continuity.
After all of that, when depressing the credit button, it will not start a game.
Questions are:
Have I diagnosed the correct circuit? (I can't find the 1st and 2nd chute adjustment anywhere on the game)
Did I miss anything on this circuit?
If this is not the right circuit, what is, and what did I miss?
