Wellcraft Boat Owners Forum

Hey guys, I have a 1982 Wellcraft 255 Aft-Cabin that I just started having an issue with connecting to shore power. The reverse polarity light is on. I have tried a different slip with shore power as well as trying different shore cables from good known working boats and shore boxes. When the light is on I cannot even flip the breaker over- I can push it but it just returns back to the tripped location. I am thinking possible issue with the main breaker? The main breaker has what looks like 3 individual breakers together. Any help on what to check would be appreciated- I am more familiar with 12V systems so I didnt want to start probing without a diagram.

Thanks for any help!

Have you tried to swap the wires in your shore power cable? (L/R)
