Ever since buying my newest Sea Ray I've been wondering about the logic of the battery setup. I have 3 batteries on the starboard side that seem to setup from the factory. One is a dedicated cranking battery for the port motor, the other two start the starboard motor and are the house batteries.
Here's where there is a little deviation. I have 2 batteries on the port side. Factory setup calls for one. The cabling for both of the batteries looks stock, but who knows. The hot wires run from the batteries into a loom that runs to the starboard side. Who knows where they go.
Last week I couldn't start the generator. Not enough juice. So here's my chance to figure out which of the two batteries is the generator battery. I disconnect one and tried the generator. Still click-click-click. Not enough juice to start. Okay. Must be the other battery. Hook number 1 back up and disconnect number two. Same thing. Click-click-click. Both batteries are weak, but they both are generator cranking batteries? I replaced the number one battery and the generator cranks fine. For now I've disconnected the second battery and will try to find something that isn't work, but for now my best guess is that both batteries are generator cranking batteries. Anyone ever see this before? Why?
One other thing. The battery I replaced is a 1000MCA cranking battery. Battery number 2 is a deep cycle battery. Just doesn't make sense.
