That's exactly the kind of anecdotal detail that I specifically was not asking for.
Why does it do that when the ground wire is long? Anyone ever try a shielded cable (properly drained)? How about twisting the ground and power wires together? So far all we have is an Old Wives Tale.
A short ground wire means that the ground path is going thru spot welds and is an indirect path (read: longer) that potentially has much more resistance than the wire to the battery will have. If you're going to do that, why bother with stipulating that the ground wire needs to be the same gauge as the power wire?
