Hi all,
The following challenge:
I'm wiring up my motor home with lots of stuff. A 5V step-down converter (from 12V) to power Apple TV and Airport Express and 18V step-up converter to power Mac Mini. Both PSUs will be powered from the same slot on the control panel, same fuse, wired in parallel. Some time ago, I have led three wires up to the actual consumers (bloody difficult) - black for ground, orange for plus and another orange "just in case". As I did not know about the 18V requirement, "just in case" seem to have happened. Now the question is, if I can use the same wire for ground from both PSUs, or I have to lead another ground cable up. If yes, would be great if somebody can explain why. If no, same thing.
Thanks' a million.
