It's like the battery is completely disconnected from the boat.
To the contrary, sounds like there is a constant drain or the battery is getting no alternator contribution when the engine is running. I would first look for a rogue battery cable that did not get connected back to that battery. next, you need to break out the volt meter and start checking for charge voltage while engine is running and current draws while engine is off.
In trouble shooting, one must start from square one. Meaning, did you do a voltage check? Is there +12v at the battery? Is there 12v on both sides of the House switch and breaker?
