'Float' voltage under varying DC loads
This post is an observation, and observation which bucks the 'this wors like this, and that works like that' mentality which pervades online forums. Empiracle data trumping theory. I can spin a di...

Designing systems, I chose to operate the charging system by sourcing alternator voltage sensing right at the alternator. And meter voltage sensing at the exact same point. Reason: An open in the charging line would lead to load dump but not to uncontrolled voltage at the alternator.
Hmmm ... it seems like no matter what you did at the alternator to keep it's voltage from going off the charts with an open line ... you should also have implemented a voltage sensing negative feedback closed loop, terminated at the load, so as to ensure that whatever/whoever controlled the alternator could set exactly what voltage they/it wanted to wind up on the load's terminals.
For instance - barring an open line - I think the OP is trying to precisely control voltage fed to his batteries ... albeit not via the ultimate of voltage sensing right at the batteries' terminals. (?)
