The Continental can be difficult to diagnose, but I would start looking here. The unit in the head has a motor driven unit that resets the hopper after every payout depending on the amounts of coin s played. Meaning, if you play 6 coins and you get 1 cherry, it will payout 2 coins, reset and do 2 more, reset and continue this until all 6 sets of 2 coins are paid. This unit is a little pickey and the switch blades need to be cleaned and in the proper positions. I was lucky when I found mine and to this day, have not had to clean or adjust it.
