My first pin was and is Top Score. It was my goal to have one since when I was a teen when it was at the local pizza joint. I paid a bit too much for the condition, but it plays fast and is very clean now and reliable. I separated the two pops with an extra relay to improve the action. Love this pin and will never sell.

Double and triple bonus for the 2nd and 3rd ball if you set it to 3 balls.

Your choice 3 or 5. Mine is on 5. Tried it on 3. 5 is better.

I bought a full plastics set from Pinball Rescue. The quality is excellent.

Not sure I get your post. The special target will light after hitting the lit star rollover and will turn off upon any scoring action that involves the score motor. The mystery bonus means that you will get 1, 2 or 3 bonuses for hitting the saucer.

That looks like it has low plays, judging from the wear on the bg. Glad you were able to save it.

Added later by a previous owner. They did not have that post from the factory.

That lane guide as you call it won't change the way the ball drains down the side. My Top Score doesn't have the guide. I modded the pops to fire independently and that improved the action considerably.

Pinball Resource sells the schematics. I support them and am glad they are around.

Ball count troubleshooting may not need a schematic. What exactly is the issue?

Don't use grease where nylon touches nylon and use a very light suitable grease, such as the one PBR sells, very sparingly on metal to metal. Most machines have had previous owners put the wrong grease on things. Also, the original 40 year old grease has hardened like glue.

I didn't write schematic for it, I just did it. I added another pop bumper relay and just separated the circuits. You will need to add a wire to the scoring relay, too.

Based on your description, I would check connections and wiring at the solenoid that kicks them down.

Never noticed that..

Should be an easy fix. Could be the AX, could also be score reels not resetting to zero...

A contact is closed when it should be open. Difficult to troubleshoot without having the machine in front of me. Is the machine setup for free play, are the coin units installed working properly, was it ever working correctly, etc? You are correct in removing power as whatever is on will overheat if allowed to stay on.

The coin lockout coil is on a rod connecting the two coin mechs inside the coin door. It shouldn't make any noise. Just cut the wire to it and secure/tape so it won't short. Then see if the noise is gone.

It is supposed to have a coil stop.

No mounting point that I can see.

That happens every once in a while. Make sure that there is a little light oil where the spinner rotates in the frame. I have found that hitting the flippers a few times will free it.

All the contact blades should be straight into the ladder. Manually operate the relay and make sure that whatever was closed, opens and vice versa.

I am amazed that they have that.

Ensure that the spring loaded contacts on the wiper are lined up to be centered on the rivets and not contacting adjacent rivets. Also check the contacts in the ball count unit for proper operation when the cam rotates.
