Really appreciate you taking the time to look into this. The info. you've provided has been very enlightening.
Unfortunately, you are likely correct with respect to the battery's current health. The only way to know for sure is to pull them and have them tested on a load tester. That's a PITA of a job, but once you get your wiring sorted, it will likely be necessary. If they are toast, now would be the time to look into alternatives, at least for the house batteries. There are lots of threads on this (unlike the Fusion issues), so you should be able to get some good ideas on how to proceed if you need to.
