Getting "polarity reversed " on Sea Ray 250 Sundancer

[tstock]

I installed 2 new batteries and hooked up shore power through a three prong 110v pigtail. Now the green LED lit up at power station showing "reversed polarity." Any and all help would be appreciated

this is a battery charger or inverter unit?

If you didn't screw around with the boats 110v power and the reverse polarity light just now comes on, more than likely it is a problem at the shore power tower. Have you plugged in there before or have they recently had any work done? Changing your batteries shouldn't affect the 110v side of the panel. It's 2 separate circuits.
