Gottlieb Bone Busters system 80B releasing to many balls
« on: May 15, 2015, 09:25:24 pm »
Hi, working on my 1st restore. Thought I had the bugs figured out... game starts normal but at some point it will release 2 balls instead of one. The switch on the out lane works, the ball is sitting on it, but it still kicks another ball out. Tried changing the dip switch's to 3 and 5 ball play, tried it in single and multi player, still does it. Any ideas?

Update, had a chance to run some tests, the switch test shows sw #27 closed. My Bone Busters schematic doesn't show a sw #27. I manually closed all the switches and only sw #1 doesn't seem to work (it's the top left spot target where you have to hit the ball that's under a ramp to get the opera jackpot). I'm wondering if it's mismarked. I have several pages of addendums but nothing for this.  The switch doesn't look open.  Tomorrow I'll dig into it and check it with a meter.
Anybody know where sw #27 is?

Check trough switches and diodes.
