Can the "shield" be used as the return ground? Meaning, if I have shielded wire containing 2 wires, can one wire supply the nav and the other the strobe, and use the outside shield as the return ground (neg)?
I understand the concept that each positive wire should have a ground that return to the "main ground buss", and not to use the airframe as the ground. Can I have a "common" ground at the outside wing rib that is isolated from the airframe to which all the negative wires of all the wingtip electrical stuff (landing light, taxi light, strobe, nav) connect, and from this common ground run one wire large enough to carry the combined current back to the central ground? If this can be done, I would think that the same concept can be used at different stations of the airframe?
Thanks.
Johan.
