I was wondering is some of you electrical gurus may be able to pinpoint this
problem. When my system is under heavy load (night), i.e. landing light,
interior lighting, strobes, navs, etc...all switches in the on position, I am
getting cycling of my alternator. It will kick on and off intermittently, and
sometimes trip my main breaker. The strobes seem to be the major culprit. I
have gone through individual switches and it seems to be related to the
strobes. I can get them to do this occasionally even during the day with no
heavy load, just strobes and the usual amenities (radios, etc.).

Think I may have a corroded connection pulling too many amps? I'm not sure
where to begin. Thanks for any input.

Steve,

 

As Marv said, the battery may be weak and that only amplifies the condition.  Another concern is where the regulator main bus voltage sense is located.  Where is your voltmeter pickup on the main bus located?  If the two are co-located, does the volt meter show abnormal fluctuations?  Is it possible that the regulator sees such a low voltage at strobe initiation that the regulator kicks out?
