So my Firepower boots,will go into audit and test modes, sound solenoids lamps work in test. In gameover/attract more controlled lamps run correctly. It will coinup and give credits. It has 3balls.
It won’t start when the start button is pressed. The diode is ok. However on both wires, why/org and a pair of smaller green/black I get +4.87VDC. In my experience, one of the wires should have no voltage.
Help!
