That's how it's connected, only combines batteries under alternator power. If you run your engine
at the dock
,be sure to switch off the shore power to the charger.
Shore power chargers such as you've described have 2 charger outputs.
WADR, that's just plain wrong.
Combiners are not "...alternator power supplied battery combiner...& ...only combines batteries under alternator power."
Combiners are relays that close when charging
sources OF ANY KIND are present.
Use ONE shorepower source to the house bank and let the combiner do its thing for all
Read your charger manual to find out if one output can provide full amperage or if you need to jumper the outputs together.
You might want to go to the Yandina website and read their FAQs, and RTFM, too.
Good luck, but with electrical
stuff, luck should have nothing to do with it.
