Very new to pinball collecting, the first game I picked up was Bone Busters @ pinfest in Allentown 2019, never heard of it before but fell into my price range, gave it a shot, and fell in love with it. I am im having trouble with one of the ball locks not kicking the ball out. It is the ball lock in the lower left corner of the table. I am unable to find schematics and am getting very frustrated. It works for a little while then seems to be inoperable for days, I have checked the fuses but all are good. I did a wire trace and seem to have no questionable sections. Any help would be much appreciated.

My first thought is an intermittent path to ground.
You can test the theory by reseating connectors on the bottom of the driver board, and in the cabinet as outlined here:

Thanks Chris, sorry for the long delayed response, I finally got to work on it this past week. While I was doing what you suggested I stumbled across a connector exactly where you said on the bottom of the driver board, that was slightly crooked, wiggled it on and boom back in business!! I really appreciate the help, pinside members are pretty freaking awesome! Hope you have a great day, thanks again. How you knew that is insane!

Manuals for Gottliebs aren't available on the interwebz. You'll need to buy one from

The grounding mod is a must-do for almost all Gottliebs.

Also check that switch to make sure it works the way it should with the right amount of throw.
