I am rebuilding a 1977 Bally Eight Ball machine. I am having an issue with the led flash sequence. I can get the 6 flashes on the board with a test jig and the 7th when I jump out to simulate the 43vdc. However when I place the board into the back into the machine I only get a locked led on power up. I am getting the correct voltages on the TP's. any suggestions.
How does your rectifier board look? Has it been rebuilt/replaced/serviced?
They always need attention in these games.
