the 929 payout counter is mechanically stepped in coin mode and electrically stepped in credit mode.
in coin mode, the game uses the odds unit and odds follower unit to multiply the pay when 2+ coins are played.
the odds follower unit design makes the payout counter reset and the game pays again, repeating the process until the game has paid X times, where X = number of coins played
for example, play 3 coins and:
- win pays
- payout counter resets
- win pays
- payout counter resets
- win pays
the hopper motors turns off after each pay and turns on again after the payout counter reset, so the pause in pay is more noticeable when the payout counter wipers have further the travel when resetting.
if your payout counter wiper reset is sluggish, the pauses are also more obvious.
when in credit pay mode, there is no pausing. The odds follower unit is not used and payout multiplication is done by the odds unit selecting different cams on the odds motor to make the correct ratio between credits added and payout counter stepping.
the game should pay smoothly in credit mode and when 1 coin is played. 2+ coins played in coin mode and the game will have the stuttering pay.
