One other gizmo I’ve found helpful, especially when working on boat electrics alone (most of the time…), is a 12-volt Sonalert (beeper) with a couple of feet of wire and alligator clips. It makes it much easier to diagnose when you’ve found the right breaker, or bad connections; wire it across a circuit, and if it beeps, there’s twelve volts there. And you can hear the darn thing just about anywhere aboard…
