[C320-list] AC reversed polarity light

[Scott Thompson]

On our recent cruise we found that the reverse polarity light came on 
when we tested the AC hookup in 2 different marinas, and then again back 
on our home pier.  Since there was no indication of improper wiring at 
any of these locations, and since we had no trouble at the home pier at 
the start of the trip, I assume that the problem is somewhere in my boat 
or power cord.  The power cord passes a simple end to end continuity 
check on each of the three conductors, and there is no sign of any 
shorts.  Does anyone have suggestions on what to look for next?  It's 
occurred to me that perhaps I need to replace the shore power connector 
on the transom.  It looks OK, but after 11 years, maybe the weather has 
taken its toll.

My recollection is that faults other than reverse polarity can cause 
these kinds of symptoms but I do not remember the details.
