David,
My intermittent problem was a broken ground wire at the
connector attached to the alternator.
Speaking of alternators on big Continentals…. In
a conversation I had at Sun n Fun with Bill Bainbridge of B & C Specialty, I
learned the Primary Alternators (not a B & C product) have multiple failure
problems. Bill recommends Aircraft Systems Inc in Rockford, Ill. (Bill has no
financial interest) as the best place to have them improved for more reliable
service. My 70 amp Kelly is there now.

Subject: [LML] Alternator Failure Question
This is probably a question for my mechanic, but can
alternators start failing after 180 hours on IO-550’s? Is failure
typically intermittent?
(I am getting intermittent drop-offs in the Amps reading on
my engine monitor – down to single digits and then negative amps in the
teens and then the system restores to normal after 1-2 minutes.)
