Weird issue here. I'm new in the community/hobby, and am hoping one of my fellow pinheads with experience with Bally/Williams 90s pins can help me troubleshoot.

Whenever I start a game on my NBA FB, the balls just sit in the trough, and are not ejected out to the shooter lane.

All solenoids are firing fine when I run the Solenoid Test, including the eject ball solenoid. When running the Switch Edges test, all the trough optos are all detecting the balls when I slowly roll a ball down the trough.

What am I missing here? Is there something else I should check to troubleshoot this?

Thanks guys!

Hey Marc, thanks for the offer. Sorry man, I need to update my profile... I'm no longer in San Jose. Just moved recently to San Ramon.

LOL I'll take it! Thanks....

I'm pretty sure it's working. I mean, the solenoid test won't run unless I hold the switch down.

Yup. I have all 4 balls in the trough when starting the game.

This wasn't an issue until recently, actually. One of the solenoid fuses on the driver board blew out. I replaced it, and all solenoids worked again. Unfortunately, this new issue reared it's head.

OK, looks like there are two coin door switches. The bottom coin door switch doesn't seem to do anything significant. However, the top switch needs to be pressed down in order for Solenoids to fire. That said, the "handle" that protrudes from the coin door, only holds down the bottom switch, and NOT the top switch. Is this normal for a Bally-Williams game from the 90s? Seems strange that the top switch is the one that needs to be held down, yet there is no hardware protruding from the coin door to keep it held down when the door is shut.

To clarify.... When I run Switch Edges test, the bottom button registers as a "Coin door closed". The top button registers nothing. However, in real use, the top button is the one that needs to be held down in order for Solenoids to fire.

Confused. Lol

OK, after doing some research online, it looks like this top switch is put in place as a safety for users vs. their coils and Solenoids. My question however is, should my coin door have some sort of bracket that holds BOTH this button, and the button below it? The bracket on there now, only holds down the lower button, leaving this top switch open.

Got it. Yeah, someone must have replaced the original bracket with another one that only holds down the bottom button. Thanks for the explanation. It all makes sense now.

Thanks. I'll try pulling it out then. This is the reason why the balls weren't getting fed into the shooter lane.
