2 Batteries need help running AMP and the builge pump

[jwhposon]

I have a 2004 SAN. The boat can handle two batteries. I have a Perko switch that works great(it has 1,2,none and all). There was an option to buy a hellring something but that costs quite a bit. I would like to know if and how to connect the in the following sequence.


1 battery dedicated start battery
1 battery runs the music and the bilge pump ( I think that little wire connected to the main battery is for your blower when the switch is in the down position.

They will both be charged at the same time.

And I want to be able to use the stereo battery to start if needed - any new perspectives?

RE: 2 Batteries need help running AMP and the builge pump

Well, I am also interested in replies as we are getting ready to install second battery on our 2002 196. I had this arrangement on a previous boat. Seems to me that Batt 1 should be hooked up to everything but the stereo and bilge pump and Batt 2 should be hooked to the stereo and bilge pump only. Both can be charged simultaneously by running in the "all" mode. If Batt 1 should go dead you should be able to start off Batt 2 by switching to the "all" mode.
