Nagging Issue - Electrical power goes dead

[flipz96]

It has to be either your battery or connectors/wires. I would start with replacing the ignition wire and go from there.

I have had it happen under certain conditions, and it has always been the main breaker on the engine. I've seen it happen on more than one boat, same thing. In one case I just tightened/cleaned the connections on the breaker. I think in the other case I replaced the breaker. It would make a very unsatisfying click when I pushed it to reset. But any time there was no power to the dash, it was always solved by resetting - or just the act of messing with - that main breaker.

I'm having this same issue. No power at all to console...bilge, blower, ignition. I have followed the electrical cable from battery to engine, checked a bunch of connections under console, nothing seems to work. I'm not sure about the main breaker. I have a Sunsport with PCM Pro Boss engine. Can someone describe what the main breaker looks like or location?
