Re: What does the reverse polarity light mean?
It does sound like a contact problem. The RP light only measures a difference in voltage between the neutral wire and the safety ground. Ideally, there should be no voltage on either of those two since they are bonded together on the power producing end.
It is possible you just didn't get the plug in all the way, or there is an intermittent on the shore side receptacle. However, if you didn't have power at all, then it would be the load wire that wasn't connected, and this wouldn't light the RP light.
And I think all of us are assuming you are using a typical Hubbel type connector that cannot be plugged in different orientations - so if it fits in the receptacle, then the wires are matched correctly between receptacle and plug.
