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…
