I use a Honda 2000 watt inverter generator on my boat to occaisionally
charge batteries. The boat stays on a mooring so I have no access to
shore power.The generator hooks up to the boats shore power plug and AC
panel then to an AC charger. The panel has a reverse polarity light and
it lights up indicationg reverse polarity when I run the generator.
With no load on the AC panel I can reverse the positive and neutral
wires and still get the reverse polarity light. When I test the output
of the generator, at the generator, I get 120 volts with the positive
and negative but I also get 40 to 70 volts when I test the neutral and
ground. I called the Honda dealer where I bought the generator and they
said they had no idea why that would be happening. The generator powers
tools or any other load without a problem. Does anyone have any idea
what might be going on? When I was building the boat in my yard there
was never any problem connecting to regular AC through the same system.

There's a discussion concerning the connection of neutral to ground at
that you might want to read.

Also, I would post your question to some additional boating or sailing
newsgroups such as alt.sailing.asa

You might also want to measure the voltage between neutral and ground
on the shore power outlet. I would bet that it would be zero indicating
that they are using a bonded neutral. The Honda 2000i, incidentally,
does not connect ground and neutral together.
