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.
