"In working on the rewiring the batteries, I need some advice. The Promariner ProTech 1220i was wired for only two banks. The generator battery was in parallel with the starboard battery. In reading the direction from the battery installation manual, it suggests connecting all the negative cables from the batteries to a common ground. My boat apparently does not have a common ground. All the negative battery wires are connected to the engine blocks, along with the 8 AWG green bonding wires. The battery charger is also connected to the starboard engine block.
The Tiara manual’s wiring diagrams are scanned, the boat is still fairly original in the schematic.
Should I add a bus bar for all the negative wiring, as indicated as the preferred method from Promariner. What would be the best way to do this? I was thinking of running one cable from the block to the bus bar from each engine. Then I can attach the charger’s negative connection, and then one from each of the batteries. I am trying to set up four batteries, the house and generator in parallel.
Any advice is appreciated. I have been in contact with Promariner and I think this question is not going to be solved by talking with them. They did explain other questions for me because the manual was lacking in information."
