I've identified the column that is causing my credit issues... on the switch matrix... right down the line each of the switches on that column cause the action for column 1 of the same row to hit.
Example... Coin 4 is on the same row as the bottom pop bumper... when I click the pop bumper I get a credit from coin 4.
Center coin is on the same row as the right slingshot. When I click the right slingshot I get a bucks credit (center coin).... the slingshot is on the same column as the pop bumper... that entire column has issues.
What am I looking for here? The fact that I 'believe" it went from working right to doing this tells me it's likely not WIRED wrong...
What's my next plan of action? Do I check the diodes on each switch in that column?
