Hi.

So, I am playing around with a Bally X's & O's, which has an AS-2518-54 in the bottom of the cab. I've installed flipper button LEDs, and was planning on dropping in a separate power supply off the main switch. However, the board has 14vdc being fed to J3-10 for the 5v regulator input. I'm guessing that I can tap into this for the the 12v I need, but I need a return. It works fine if I just ground it - assuming of course that the LEDs have a tolerance high enough to take 14vdc, instead of 12 (we'll see!) Anyway, my thought was to take the spare return/ground that's on J1 (Playfield), but it would be nice to keep it all on J3. Is there a reason I can't wire the LED return to say J3-5 (5v Regulator Return)? All the returns seem to terminate to the same ground plain, but this is where my knowledge of electronics reaches a bit, so I thought I would query the group.

Thanks.

Hi.

Hmmm, maybe. I didn't think there was 12v going to the door, but I'll check. Agree with keeping things separate. I was hoping that given the minimal amount of LEDs we're talking about, and the low draw, I'd be okay.

Yes. What I installed was the BriteMods buttons, which are 12v. Given how these buttons are installed in the cab, I don't think I can effectively back-light these with 6v LEDs. That, and the BriteMods are much...brighter.
