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.)
