Machine was working other than small glitches like 100 counter missing once in a while.
Now on power up it will usually allow 1 play only (not second player) and when that game is over it will not allow another play regardless of credit wheel setting.
AFter the game is played, the only way to restart is to hit the kick off switch on the bottom which powers down the machine. Then hitting the start will do a full reset, and let you play 1 player game, but again, not 2 and not after the 5 balls are used.
No blown fuses. tried it in both free play and with credits on wheel.
All contacts in lower cabinet have been cleaned and tested for make/break contact.
This game is scheduled to go to TPF, so we are in a bit of a panic to get it going by Thursday to load.
