We call ground ground. But the return from the negative battery
feed is called return, not ground. Just like neutral is not called
ground in a home electrical system even though it is connected
to ground at the main breaker panel. The returns from equipment
in a CO are connected to ground at the main battery power
distribution frame. What really throws the new guys is that +
goes to ground and - goes to battery. Boy have I seen some good
arc welding. Good thing Craftsman has a lifetime warranty on
tools.
