I think I see where you are going. The buss bar you're talking about is on the negative side. The positive side flows through the controllers, which decide where to port the electricity. Electricity from the dc generator
can go to the batteries or to the motors. The dc generator
gains efficiency by only producing the power required, unlike constant rpm
ac generators. I don't remember if power from the generator has to hit the batteries first. When you are regenerating, the controllers port current
to batteries. You manually watch the batteries and turn on the water
heater or something if you have too much charging current
Bottom line: you have an extremely complex system and you shouldn't mess with it until you have lived with it for a year or so and have thoroughly figured it out. The 420's are wired completely differently, but you may be able to get some insight by comparing notes with a 420 owner. Likewise, get in touch with the catamaran
company who had a 410 in charter
for a few years. They may be able to give you some insights.
I think you ran across the reason other 410 owners upgraded their gensets, to 17kw iirc. You can cruise
at 6.5 kts drawing an average of 40a per motor
. But the current does jump around a bit, and if your generator kicks off every time you exceed 80a, it would be a real pain. You are not the first to face these issues, but the club is pretty small. As I said, other owners solved
it by upgrading their generators.
I seem to recall
a procedure for resetting the link 10 when you know the batteries are fully charged but the link 10 says otherwise. I'd direct that question to Xantrex who makes the link 10.
Here are a couple of links to check out if you are having trouble sleeping:

Congrats on the boat!
