Either way, its a short, but a basic short wire to wire or "Ground" Wire to ground. When some wires short to ground, multiple wires are affected and multiple readings show up. Either way the problem's have to be corrected. Same w/ comp. winding to winging or short to ground,....also Shorts causing instant chaos.
That a good question tech man.To me i think of a short as a conductor with a voltage drop or loose connection sometime it work other times not.
As for a ground instant trip breaker or blown fuse,or transformer or sparks or even an explosion like a lockup compressor and you stick a hard start on it and it blows a terminal causing a 10ft flame thrower.lol
I like the grounds better easier to pinpoint the problem.
