OK, Thinking-Cap Time...

C) Others mention the split master.

.stuff snipped

I'd say just replace it, but know that a $5 switch
like that becomes a $500 switch once annointed with FAA Holy Oil.


Actually, that split switch for Jay's plane is a fooler. I bought the
official Piper part from Des Moines Flying Service (DMFS.com) a couple
of years ago and I remember it being less than $50. Some day I actually
have to INSTALL IT!

I like the idea of the "Bypass wire" test. I could do it on the ground
because my Cherokee does this all the time.

Good Luck,
Mike
