The machine has an incomplete reset process. You can either see why the credit unit is not subtracting a credit, or why the score motor stops running, which is preventing the completed reset process...

Check the credit unit reset solenoid (coil) circuit first. Check the following:

Coin relay switch - yellow wire and red/white wire
Credit relay switch - yellow wire and orange/blue wire
1st coin chute adjustment plug - orange/black wire (make sure plug is clean and properly seated)
Score motor switch 3B - orange/black wire and white/brown wire
Credit relay switch - white/brown wire and white wire

Make sure these switches are clean and adjusted properly.

You can also check the total play meter. Does the meter's numbers increase when you push the credit/start button?

For the score motor circuit, check the following:

Outhole relay switch - yellow wire and red/yellow wire
Bonus score relay switch - yellow wire and red/yellow wire
Out rollover relay switch -yellow wire and red/yellow wire
Aladdin's alley relay switch - yellow wire and red/yellow wire
300 point relay switch - yellow wire and red/yellow wire
Reset relay switch - white wire and red/yellow wire
Coin relay switch - white wire and red/yellow wire
2nd coin chute switch - red/white wire and yellow wire
3rd coin chute switch - white wire and red/white wire

Make sure these switches are clean and adjusted properly...

Let's continue with the the question, "Why does the score motor stop in the middle of the reset process?" We can look at another circuit that sends power to the score motor, which includes a score motor switch. Check the following:

Score motor switch 1D - white wire and black/white wire

Also, does the total play meter's numbers increase when you push the credit/start button?

For the score reel issue, there might be a problem with the 9th position switch or EOS switch on the 100 point relay that is preventing the 1000 point score reel from advancing. Closely look at the switches on the 100 point relay to make sure they are adjusted properly.

Okay, now let's see why the total play meter does not work. There are only two switches that send power to the total play meter and there's the 1st coin chute adjustment plug. For troubleshooting this, make sure the adjustment plug is in the "1 play" plug hole. Here's the switches in the total play meter circuit:

Coin relay switch - yellow wire and red/white wire
1st coin chute adjustment plug - orange/black wire
Score motor switch 3B - orange/black wire and white/brown wire

When you press the start/credit button, is the coin relay coil energizing? And does the 3B score motor switch close? Make sure the 1st coin chute adjustment plug is clean and it's making good contact when plugged into the "1 play" plug hole...

If you confirmed those two switches are closing at the same time and the adjustment plug is making good contact in plug jack, then this circuit is complete and it should advance the total play meter one digit. Most likely the score motor switch closes briefly and sends power to the total play meter.

Even though the switches are closing, they might not be "bridging" the power to each switch blade. Sometimes you have to "scrub" the contacts clean to make sure they are making a good connection. Also, check for broken wires at the switch stacks. Any broken wires at the total play meter?

Another way to test the circuit is to adjust those two switches so they are in the closed position. Turn off the machine and use a switch blade adjustment tool or some small needle nose pliers to close the switches so they are always closed. Adjust the switch blades at the base of the switch blade stacks. Then power on the machine. The total play meter should advance one digit and the meter should start buzzing. Then turn off the machine. This will prove the circuit is working properly. Then adjust those switches back to their original positions.

Also, check the playfield Jones plugs that plug into the main board. Turn off the machine, unplug the Jones plugs from the main board, make sure they are clean, and then plug the Jones plugs back into the main board and make sure they are properly seated...

Just to confirm, when you pushed the start/credit button with the playfield down, the ball was in the outhole?

A clue to this problem might be seen in the backglass. When the machine is going through the reset process, is the "game over" light on in the backglass?

We had some heavy rain here in Austin with some wind damage during Hurricane Harvey... Looks like Hurricane Irma will hit Miami and head north. It's looking like the storm won't be as bad on the west side of Florida... But, keep looking for storm updates... Be safe and take care...
