I have a Sailfish 252 with dual Yamaha 150HP HPDI's. There are two start batteries and a deepcycle house. There are also 3 seperate switches (1, 2, both, and off). I believe the previous owner added the third switch whcih doenst seem necessary to me. There is also a 3 output guest charger isntalled. I know there are many different ways to wire the configuration, however i am looking for somthing that is simple. I have thought about adding a ACR / VSR but would prefer not to spend more $ on the boat this year. Is there a way to use the existing parts (maybe do away with the 3rd switch) and achive battery isolation during discharge and combined banks during the charging cycle? also, should the house battery only be used while the motors are not charging the banks or at all times? if i can only achieve the above mentioned using a acr / vsd, should the guest charger be wired to each battery or only to one of them.
lots of questions i know...just trying to get it right!
