[Public-List] testing my mast head light

[Robert Kirk]

Jeff... Finding intermittents is always a tough problem. Naturally, the 
problem must be at a connection, wire or the luminaire (word forced on us 
by those darn Canadians) itself.  Likely an insulation problem  or an open 
at a bad connection.  The only decent way to identify an insulation problem 
is with a megger. Also use a continutiy tester; Alligator clips on a 
battery is fine, but a little cumbersome. But as long as you have the mast 
down, it's probably quicker to run new wires and remake the connections.
