Quoted from Indusguys:
Hey guys, thanks for all the help so far. I got the Kahr board and even though I didn't need it, I plugged it in, everything has been working fine. Until tonight, when my son was playing I noticed the pop bumpers and the slingshots weren't firing, when just a few minutes earlier they were working fine for me. I went into tests and they all fire fine. I looked at all connections underneath play field, and also on top, checking all leaf switches. I couldn't see anything out of the ordinary. Is it odd that just the slings and bumpers would stop working and the rest of the game would play fine?
What is my next course of action?
