Yes, I understand this and that is exactly what I did for this ground wire. However , when testing the CB from the Alternator thread
Alternator / Voltage Regulator , I just went from stud to stud and disconnected no wires. . I guess my thinking was I just wanted to see what was running thru the breaker. Maybe that is why the very low reading. I will post this last part on that thread to avoid confusion to future readers.
