Working a project Ice Cold Beer. Rebuilt power supply and found a reverse wired big cap. Also 12VDC unregulated was reversed to the main board. Also I replaced one of the large bridge rectifiers.
Game boots. Goes into attract mode with display reading zeros and the star lamp illuminated. Some holes have no lamps on. Hole 9 and 10 weakly blink on and off.
Game will enter diagnostics. Tests 0, 1, 2, 3, 4, 5 and 6 pass with only hole 3 and 10 switches failing. I didn't do tests 7 through 11, but test 12 does have the alternating sound outputs differing in intensity which I guess as test passed.
I don't have a game ball so I tried holding the ball gate switch with no improvement.
What does it take to get the game to start? Do I have to go through the other tests with an O scope?
TIA,
Barry
