right, if you 'miss' a critical step, by advancing the 'test' too rapidly, you might 'see' something that's not really there - missing a 'part' of the step - meaning individual steps.
It's critical to formulate a plan of attack, understanding the 'flow' of the electricity, where it starts, the many points it touches along the way, and where it 'ends'.
Part of that 'issue' was the revelation that turning OFF the camper's MAIN BREAKER did nothing to change the 'sounds'... now, THAT was a new one on mE!
Yes, I think my son now understands the critical steps involved in making sure that you're not 'forgetting' to switch something OFF, especially. Even when we were close to having the problem solved, and had tested the final wire bundle, he still wanted to go out and actually/physically UNPLUG the camper - I don't blame him, and for safety sake, certainly go for it!
