Hi everyone, new here and to Grand Banks, I just bought a 1979 36 and I had some questions about the DC system. The previous owner never had a true house bank he just used the 2 8D starters for house power and alternated using port and starboard just using the boat for quick afternoon trips.
I would like to move things around so that the port side battery (currently 8D) is the starting battery for both engines and the starbord side will be house. Now I'm no expert but I've worked out what I think will work in order to switch it around and maintain having one alternator from each engine charge their respective bank.
My plan is to move the starter motor lead from starbord battery to port, then move the leads from the starter switch, breaker, stop switch, ect over to the port side of the battery switch, this subsiquently gives the port battery full contol of starting both engines while leaving the alternators where they currently are.
My main question is what to do with the leads in the solenoid panel that seem to connect both battery banks in parellel upon starting and if that even is what they do??? My theory is disconnecting them will stop the batteries from connecting and essectialy isolate the banks.
I attached the DC schematic I got with the boat, which seems fairly accurate as all previous owners didn't upgrade or modify the battery system to my knowledge. Thanks for any help/input.
