"34' boat, twin 454's.
I have 2 engine start batteries and 1 house/acces. battery.
3 Bilge pumps all coneccted to same house/acces. battery.
Should the pumps be on different batteries??
Automatic charger while at dock always on."

"Joe I don't know what makes more sense OFFICIALLY but on my 34, there are 4 pumps ...we use 4 starting batteries and 3 batteries for the inverter/charger. 2 pumps are wired to one set of batteries and the other 2 are on the other set of batteries..AND it was a good thing.

Recently, a dashboard overide switch went bad and in our absence, 2 pumPs ran day and night for about 5 days. Fortunately the charger picked up on the problem abd kept re-charging the 2 batteries.

The week before ...we had no shore power....if all 4 were drawing from the 1 bank, our batteries would be nearly gone with no replenishment. Had we needed the pumps for any reason......Yikes!"

The redundancy offered by Al's setup is worth the effort to change the wiring.
