When I removed the tape, had the gate open and special lit, it gave an add-a-ball and points, but continued to do so non-stop and kept trying to add balls even when 9 balls were reached. (By the way, the bottom trough roll over switch works as it should.
I can make the game stop adding extraneous extra balls and points by forcing the TROUGH RELAY open, or by moving the BLU-B wire switch out of contact on the trough relay. I can also make it stop by manually activating the reset relay.
I've just noticed if the gate is open but 'special' is NOT lit, closing the upper trough switch will pop up the 5,000 point drop target (as it should) but also starts endlessly adding extra balls and points. That must be a clue.
IPDB has the manual but not the schematic. I have a schematic but in poor shape. I'll include two snippets.
Maybe there's a score motor switch that should end the scoring and add-a-balls after one cycle, but my skills are not good enough to find it. I see where the trough relay holds itself on, but not what releases it.
