Generator won’t charge batteries
I missed you were running the Yammi as the shore power. I was thinking you were using it just to keep the house batteries charged via a separate charger.
Javelin may be into something. If that 50a breaker is tripped that would cause the issue as you look at the wiring diagram.
And no worries.... glad to try to help. Even though I don’t have the same rig a lot of the systems are very similar.
