Hi friends, I just picked up a 1980 J/30 on Lake Norman, NC. Her name is Syzygy. Has good batteries and the engine fires up and runs smooth. My questions is about the electrical panel that controls interior lights, extrior lights, VHF, ext. The owner tells me everything works but he no longer lives at the lake. I see the shore power switch but no other breaker that would allow the other power to come on. Am I missing something? Thanks for your help!
