I thought I would pick the brains of the expertise on this board. My slip neighbor has a 2004 Chris Craft 33 with a westerbeke generator. The AC stopped working on shore power but works with generator. Just came out of nowhere. He has two 30 amp cords one dedicated to power, other to AC. Switched outlets,switched cords, switched breakers (two breakers for we believe shore power and ac)...no changes. No matter what...same result. Could there be a bad transfer switch somewhere? Any other ideas? Power panel appears to show no Air conditioner shore power. Manuals are lacking.
