Hi, I have a Beneteau 361 year 2000 with 2 battery switches, one for house and the other for starting the engine (a third one is for the ground and always on).
There is a link between them that combines them. I understand that they have to be on for the alternator to charge the batteries. If you close (OFF) the start battery switch the alternator will only charge the house battery and vice versa. When they are both ON, the alternator will charge both battery bank and I think that this is a problem. Since the start battery is always almost full and requires very little charging won't the regulator in the alternator reduce the charging voltage and current to the house battery? Someone told me that the start battery would discharge into the house battery bank and both would start charging from that point. I have 500Ah AGM house battery bank and 100Ah AGM start battery I am afraid that the alternator might not charge the house battery completly.
I thought that I should install a BlueSea remote battery switch for the start battery and also a BlueSea remote battery switch to combine the house and start battery instead of the fix jumper between both batteries.
Any input, comments and suggestions will be greatly appreciated.
Thanks in advance for the help
