Quick ?, should my alternators charge my house battery? Almost all of my electronics on the bridge are powered by the house battery which is the largest AGM available and brand new. I have 2 12" MFDs, autopilot, radar, stereo with amp, VHF w/AIS and fridge all running while under way. Yesterday did a two hour cruise stopped for 3 hours with everything off but the fridge and radio on with no music playing. After about an into the hour cruise home with everything back on I received a low battery message on my MFD. I Fired up the genny and of course the charger kicked in at high amps for the initial charge and Agradecida was happy again.

By the way Fayette Michigan is a fantastic harbor and cool place to see. Brand new docks with power. Make sure to hit Sherry's Port bar. Its about a mile walk south past the cemetary for cheep beer. Not a culinary delight but nice walk and very friendly people.
