When I have time to drill the lock and get inside I will start to diagnose it. I am not very skilled in that area, but I am excited to learn the more technical side of arcade machine ownership. So far I have installed a cap kit in one of my machines. I also refurbished the steering controls on my Championship Sprint cab. They sucked when I bought it. I had to disassemble the wheel assemblies, clean them up, and lube them up. They work great now. I also had to solder the connector back onto the optical sensor, and add coin mechs to the coin door. That is about the extent of my knowledge so far. My Defender cab developed some graphical glitches last week. I hope to tackle that next weekend.
