Quoted from davebart5:
I notice my PF GI lights don't go dark when I start a game and when multiball starts.
Anyone have advice or suggestions on what could cause this?
I don't see this as a game adjustment setting in the manual or anything.
GI effects are usually controlled by one or more relay(s), in turn controlled by transistor or mosfet circuits on the driver board.
Usually this can be tested as part of a game's solenoid or coil test. Stepping through the various coils and flashers, you'll come to one marked "relay" and you should hear it click (and flash associated lighting, if it's a lighting relay) if it works.
The game manual will list these circuits, but System 3 is pretty awesome about labeling them on screen as you step through, too.
If the relay does not work in the test, it could mean the relay is bad, or its associated driver (transistor / mosfet) is bad.
