Cabling for pennycap system

[JAG]

Not sure the question - are you looking for the wiring diagram, type of wire, location of wire?

were all tanks affected?

My experience with any electrical issues after someone has been inside wings, panels, etc, is that you break off a wire at a terminal or crimped connector (accidentally of course). The first thing I always trouble shoot is the circuit to ground. Often times a bad or broken ground is the culprit.
