So, this is new for me (first boat.) When the boat is connected to shore power at the dock I switch to “house power.” For cruising I switch to “battery.” I went out today and I had a Warning light on the digital display that said the battery wasn’t charging. It’s a 2016 extremely low hrs. Stored and serviced over the winter.

Lastly, the digital display showed both battery charge levels... one was totally charged, the second one was a bit more than 3/4 charged. Was the warning was an anomaly? I cleared the warning and headed back to the dock. It didn’t come back.

12v is supplied by the house batteries and their usually recharged by the engines alt. When on shore power the converter is used to supply 12v to the house to recharge them.
To check alt output, turn key to on, look at voltmeter reading, start engine and go to 1500 rpm, look at volt gauge for an increase.
Also if using flooded wet cells, check the fluid levels
