I have a 2007 Sea Ray
240 Sundancer US model. I live in Europe
and it is fitted with a 220V-110V stepdown transformer for the shore power
I just bought the boat, and when I tested the shore power
while the boat was sitting on the trailer, everything was working fine.
Now the boat is in the water
and the Reverse Polarity light is on. I have tested the shore power, and it is indicating normal, with a hot a neutral and ground with zero volts between null and ground.
I have not changed anything on the boat.
The light comes on whenever shorepower is connected, before anything is turned on on the main breaker panel. Even the "shore power" switch is off. When I turn on the shore power, the voltage indicated is only 100V.
I have measured the secondary side of the transformer, and it measures 110v between hot and neutral, 110V between hot and ground but 220v between neutral and ground. This is while the transformer has been connected. I cannot disconnect the 110V side without cutting the wires, but that might be the next step...
I have tried to rotate the power cord to change polarity, without any result.
Anybody with any suggestions?
Thanks in advance,
