Thanks, I will fine tune when next on the boat. Pretty sure I helped ruin one of the 2 8Ds by somehow setting float too high, but it is 5yrs old, the other is 4yrs. Just bought a new flooded one to fit (ugh), specs of the one delivered exceed those advertised, CCA 1100>1280;Amp 200>225, looks like I scored an upgrade. IG design is one batt serves each engine for start and house, they get auto combined for starting, I can select either or both on the main switch for house. No dedicated house and start has never been an issue except just after purchase when I discovered how bad the batts were, the genset and charger were my friend.
