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.
