[C320-list] Reverse Polarity Question

[Scott Thompson]

The reverse polarity light detects any significant voltage difference 
between neutral and ground at the panel. There should be no voltage 
difference because these circuits are supposed to be connected together 
"on shore" or in this case, inside the generator. However if the "shore" 
connection has a bad connection on the neutral leg then there will be a 
voltage difference between neutral and ground because some of the 
current will flow through the ground wire instead of neutral.

The bottom line is that you probably have a bad connection in the shore 
power connection at the stern, which can start a fire. So yes, it can be 
bad for the boat!

When I run the generator all my breakers are off, and as the generator is running I turn on the breakers.  After that the reverse polarity light comes on.  Has anyone had this similar problem?  Any suggestions?  And is this harmful to the boat in any way?  Is it possible this happens because the generator isn't grounded?
