Yes. I have seen a toasted BA23 power harness...
The end result was that the longest wire
(greatest resistance) heated up the most and eventually went phut,
No. The wires
are connected in parallel. They have different lengths and
thus different resistance - the longer the higher. "Current allways uses
the way of lowest resistance." So the shortest wire has to carry a
higher current than the other wires. The wire can carry this higher
current, but the connector can't. So the _connector_ heats up and "the
magic blue smoke escapes"...
Solution was to use equal length wires (=equal current distribution
among wires/connectors) and better connectors that can carry higher
current.
