I went to the reno nevada area a lot of years ago and bought a few bingos from a guy who was a bally field tech, operator, slot designer and used machine wholesaler. The schematic symbols and style is also the same, so the circuits and troubleshooting them is what I'm comfortable with. Stuff like relays, stepper units and cam-operated switches carried forward into the slots and flipper pinball games. My self-taught background is bally bingo pinball machines. I get interested when the problem is how a game function is implemented in the circuits. If you stop having an issue, you know it's the zero switch being flaky due to adjust/clean/pitting.ĭon't ask me anything about the mechanical parts of the machine :-) L ots of people here have way more knowledge and experience of the common problems, methods of troubleshooting and maintenance. The payout counter reset coil will fire on every handle pull, but that's harmless except the bit of wear-n-tear. If you want to prove the issue is the zero switch, jumper or misadjust it closed permanently. It's fiddly since the moving blade doesn't move a big distance.ĥ] step the payout counter once and verify the switch is closed. Ideally the blade should be on or almost on the pawl still.ģ] reset the payout counter so the pawl is lifting up the moving bladeĤ] adjust the stationary blade for a small gap. The goal is to have an open switch at reset, and a solid connection at step 1+.ġ] step up the payout counter a times to ensure the pawl is dropped awayĢ] bend down the moving blade a bit to add some tension against the stationary blade. Since nothing is pushing the moving blade down against the stationary one, all you have is moving blade tension to make a good mechanical connection. This is one of the exceptions to the rule that you 'don't mess with the moving blade'. if it's barely touching, it won't be reliable. You may need to bend the moving blade where it enters the stack so it exerts more pressure on the other blade. Yank the hopper unit out and make sure that switch is clean and closing well when you manually step the payout counter up once. Since you took care of the B-3 switch, the only thing left is the zero switch on the payout counter and the plug connections. Even if the payout counter didn't reset on a handle pull, it should try and reset every handle pull unless the zero switch is open or the b-3 switch wasn't closing.
