if I understand the issue correctly, you haven't gotten to where Z1 and Z2 matters yet. Even if your wipers are mispositioned, the player unit should be stepping if AX is tripped, P5B or S switch is closed, the score motor is running and score motor 1A switch is generating pulses.

dmarston is saying the issue is an AX relay switch (because you stepped the player unit manually to position 20 and Z1 did nothing).

To test, you have two options:

1] jumper from the power rail (red highlight on schem below) to the YEL-BLK wire on the most convenient place to get to it (yellow highlight on schem below).

2] use a voltmeter with one probe on the black power rail (most coils have one lug attached to this - purple highlight), other probe on YEL-BLK and see if you have around 25VAC. If not, the AX relay switch isn't working.

3] just check/clean the AX switch with the YEL-BLK and RED-WH wires on it.

the schem chunk below is much bigger than needed. For a coil to fire, you need a path from the power rail on the right (red highight) to the right side of the coil symbol.

if using a jumper, you can attach one end to the power rail anywhere it's convenient to access ... it's all the same wire daisy chaining around.

attaching one end of the jumper to the power rail is not the only way to use a jumper, but when doing it that way you are proving you have a good path from where you put the other end of the jumper all the way to the coil IF the coil powers.

ok, so you're at least to the second half of step 5b in the sequence markg has in post #2.

if the Z2 relay is unpowered, the player unit should have continued stepping then stopped at its home position. You'd need to start checking the sequence at step 6.

if Z2 didn't unpower, that would be a problem with the score reel switches. There's two switches on each reel involved in reset. One opens and stops the reel from incrementing when it gets to zero, the other is in the add player unit step-up circuit and needs to close when the reel is zero.

jumping the switch on the R relay is cheating ... that switch should be open except at initial power on. It opens immediately when the game is reset and stays open forever. Jumping it kinda aborts the reset sequence.

it's the DX switch that should be closed to complete the path to AXR and BXR.

take a look at what the DX relay is doing. If it's tripped, push in the armature plate with your finger so the relay latches (resets / switches lift up). If that finishes the reset sequence, then as markg said the DXR coil isn't firing.

btw, the schem oopsed the label on the R relay coil symbol. It says "tilt hold relay (R)" instead of "hold relay (R)".

I see this is mostly a repeat of what mark said in the previous post ... sorry about that.

game over relay (Q) not tripping will cause the score motor to stay running.

the O relay stays powered until the ball is kicked to the shooter or the Q relay trips, and O causes the score motor to run.

the circuit path for the Q relay you need to check is the one thru the coin unit, O, BX and motor 2C switches ... assuming the Q relay trips at power on so you know the coil is good.

take a look at switches on the highlighted path below and the motor 1C switch (forgot to highlight that).

when the ball is staying in the outhole, look and see if the O relay is powered.

the circuit in post 36 is mainly addressing the ball not leaving the outhole.

closing the outhole switch with your finger can push the switch blades more than putting a ball in the outhole.

hold a ball in there and check/adjust the switches. Make sure you have good switch overtravel - i.e. the contacts should touch before the ball hits the bottom of the outhole. The additional switch blade movement after the contacts touch makes a better connection that is somewhat self-cleaning.

if you are getting stuck figuring out the issue in howard's circuit, one way to see what is going on is to pull out the score motor service plug. That disconnects the score motor, so you can turn the score motor cams manually and watch what happens.

try not to leave the score motor in a position where a solenoid (coil with plunger) is powered for more than a few seconds when looking around, and don't do manual score motor rotation when the 120V bank reset coils will fire or you'll probably blow those fuses.

note for the player to advance, the DX relay needs to trip. Make sure you score 10 or 100 pts before activating the outhole or trough switch manually.

1] reset game and score 10 points. Verify DX has tripped.
2] remove score motor service plug
3] you can ignore the outhole if it's working ok and just close the trough switch and let go. The P relay should power and stay powered.
4] turn the score motor cams by hand until score motor 2C and 1A are both closed. See the score motor timing chart ... it will be the second time the score motor 1 switch stack lifts up. Stop turning the score motor cams.

at this point, the circuit howard highlighted should be closed and the add player solenoid powered. If it isn't, you can use a jumper wire or voltmeter to figure out what switch in the circuit is not closed.
