I am having an issue with this machine continually rebooting itself at random intervals. The machine has three new Alltek boards - solenoid driver board, MPU board and lamp driver board. The only original board is the power supply board. I thought I had a connector issue but if I move all the board connectors, I can't make the issue happen. I have heard of this on Williams games but can't find an existing topic for a Bally that helps me. Any ideas where to start?
