It's that time of night again....pinball time!

It's been interesting. I think we are narrowing the issues down, but I'm still clueless as to the solution. Here are my findings.

Blue wires on connector (tested previously): 15.06V AC

Bridge rectifier:
Blue wires: 15.08V AC
Black wires: 0.04V DC (red on black leg, black on cabinet braid)
Purple wires: 0.16V DC (red on purple leg, black on cabinet braid).
