United Hawaiian Shuffle Alley
Hi, I have a 73 United Royal Hawaiian Shuffle Alley, which worked great for about a week. Now it seems like the strike zone switches don't want to work. The game still works but will not give a strike or spare because the proper pins are not going down because of the switches. Ive been through the relays and various other units having to do with that circuit to no avail..some help would be appreciated....thanks dave

The strike zone switches are part of the easy strike circuit. There should be a setting for it. If not off or on for the full game, only certain frames would allow easy strike, so it would be tied into the frame unit disc.
Has the wax pan been emptied?
Has the puck roll over switches been checked and cleaned?
Are both left and right strike zone switches not working for easy strike?
Are the pin latching trip coils pulled in from the rollover switches or from the bank?
Do you have the schematic to post snippets of the circuits?
