I would hate to be paying that guy's bill. He flips 3 ACC switches, and just because he doesn't hear anything, he assumes there is nothing wired to them. From past experience, he orders a new trim tab controller, without checking any connections. And he orders a new live well pump, just because he hears it run, but doesn't see any water.
Maybe he did some investigating off camera, but that is not the impression he gives. I guess the folks in that neighborhood don't care what it costs.
