Carver 350 Mariner Battery 1... 2..... Both
My 2001 350 mariner has the batteries set up as follows.
The battery switch in the salon safety breaker panel has 3 positions 1, 2, and Both. According to the Carver documentation the battery selected will supply power for starting and house and will be charged by the alternators when running. They recommend alternating the batteries between 1 and 2 and that Both should only be used when one of the batteries cannot start the engines.
I recently replaced battery 2 (Group 31 deep cycle / starting) with 4 Trojan T105 6 volt arranged in a series / parallel arrangement.
After re-connecting everything and testing the voltages etc. I have the following situation.
Battery Switch in Position 1.
House OK.
Port Engine Start OK.
Starboard Engine no crank but the alarms and fuel pump run with key in the run position
Battery Switch in Position 2 or Both.
Everything is good both engines start and house is supplied.
Each battery has 2 negatives connected that go to various locations on the engines etc... very hard to track. My suspicion is that I may have upset this when i re connected things back up.
Thanks in advance for any thoughts or suggestions.

I assume you are referring to Positive cables from the starter to the switch. I guess I will have to pull the panel in the Salon and take a look. I hope the wires are tagged
