I had the 60 amp alternator breaker pop Saturday after a difficult hot engine start (fuel injected Lyc w/101F OAT). I have a Plane Power 60amp alternator from Van's.
After reviewing the data log in the Advanced Flight Systems engine monitor I discovered that the breaker held at 60 amps for about 10 seconds before it popped. The breaker did its job but at the same time the battery volts never exceeded 13.8v so I didn't have a runaway alternator. I bypassed the breaker and monitored the amps/volts closely and found the the amps peeked at 65 and came down gradually after ten minutes to its normal 10 amps.
I spoke to Stein and Dick at Plane Power and they both agreed that a 70amp breaker will probably solve my problem (before anyone ask, yes the wire will handle 70 amps)
Has anyone experienced this same issue?
