Hi Huntindog,
I did not say the house batteries were not getting sufficiently charged. I said the house batteries were sending power to the engine when I was running the head lights and other loads.
If you read the entire thread, yesterday the house batteries actually got into float mode--from the solar panels.
I think the issue is the AGM jars having a higher voltage than the Marine battery that I'm currently using as a starter battery. It is old and tired.
It may be the alternator is starting to fail.

Certainly I hate dragging around a generator--but since I normally have one, upgrading the alternator is way way way down my priorities list.A 7 page thread on your batteries not getting sufficiently charged while driving.... at night. But your choice is to not invest in an alternator upgrade.. Solar instead.:h
