So my brother and I noticed something last night while playing. Off work today with a bit of flu, and checked on this a little bit. Looking for advice here.

My Player 2 10,000 score reel seems to "slip" from time to time. I really don't know what else to call it. At times, the 10,000 reel will increase when it shouldn't be increasing. Two things about this:

1. This doesn't usually happen during most "normal scoring" instances. For instance, if the score is at 47,000 and the player hits a 5,000 bonus (say on the swinging target) the score reels will advance properly to 52,000. However, if (for example) the spinner is hit and is lit for 1,000 as opposed to 100 then you can clearly see the 10,000 reel increasing during the spin when it shouldn't be. To me, this is potentially because the mechanical action is taking place much faster from the spinner pulses than it normally is from other scoring occurrences.

2. This tends to happen less once a few games have been played on the Player 2 side of the game. Usually by the 3d or 4th game of a session, the tendency of the 10,000 reel to increase extra times seems to go away, sometimes completely.

In a case like this, should I be more concerned with the switch contacts that are "made" when the 1,000 reel goes from 9 to 0 (and thus pulsing the 10,000 reel), or is this "slipping" more likely the result of the fingers in the contact that travels along the circuit board?

All my score reels were broken down, soaked in an ultrasonic and rebuilt last summer. All coil sleeves were replaced at that time, so they are all less than 6 months old.

Thanks.

score reel slip is usually the arm that rides the gear to prevent the gear from going backwards. if that arm is not engaging the gear properly on the return end of stroke of the plunger that backwards movement can happen. you shouldnt be able to turn the reel backwards by hand in any of the 0-9 positions. if the score reel has a wiping disc board the extra tension of the wiper might not allow the full return of the plunger. you can either adjust wiper tension or cut a few turns off the return spring.

This usually causes a reel to lose points, not gain them.

Hey SBK, it might help to get more info from you about EXACTLY when the issue happens and when it doesn't, and EXACTLY what happens.

Is it only spinner shots that will cause extra scoring? Is there anything else you can do to artificially reproduce the issue?

It wouldn't hurt to inspect those switches. It may just be me, but I don't understand the second part of the question (about the fingers/circuit board).

i would check the 9's position switch on the 100 reel to ensure it isn't "bouncing"...

Let's do this...

My brother is coming over again tonight to play (go figure) and I will record the first few runs on player 2 so I can try to isolate an instance of the issue in question and post footage of it happening.

It is hard to watch the reels and play at the same time for diagnostic purposes, but tonight I can just watch while someone else plays so I have a better idea of when (and perhaps how) this happens.

Thanks everyone for their help.

Can you tell me what you mean by "bouncing"?

Sounds like a plan. Let us know what you find out. And, meant to say it before: feel better!!
