Working on a bowling queen. Problem is ball release stays energized so balls are unlimited. Also 10 pt bumpers or pop bimpers dont score. Looked at M relay and all looks good. Any ideas I do have schematics. Thanks

The Ball Release lockin is waiting for either the 1pt (N) or the 10pt (M) relays to activate, opening a normally closed switch on them. (So basically it keeps allowing ball 1 to be played until at least 1 or 10 points are scored.)

Check the schematic for the M and N relay logic to see what makes them score (will be playfield switches).

Ok if I manually activate M relay ball release deenergizes. But the 1 and 10 Pt relays are not working. Coils are deenergized so its not a stuck playfield switch. Heres a pic of the M and N relays in schematic. Never have had this problem before.

Start with checking score motor switch 1C first to make sure it's clean and closing, and then work right to left checking the other switches. Also check the jones plugs leading to the backbox.

Pop bumper lights work fine. Cant seem to find the one common switch for the target lights. No loose wires either. Stumped.
