Voyage 43 wiring diagram

[CaptRob725]

Hi,
I am looking for an original wiring diagram for a 2000 Voyage 43 catamaran. We are replacing batteries and when installing the second bank the positive cables are arcing onto the positive post. Bank 1 went swimmingly, plug and play. Not so with bank 2. We replaced 6 12v Lifeline batteries ( 3 per bank ) with 8 6v Trojan T-105's wired 2 in series and then paralleled to make 2 12v per bank. Checked all connections and all are as before but one positive lead on bank two to the bus bar arcs and heats up when connected. Any ideas where I can get a wiring diagram for this boat. It is a friend's boat and I am helping him get it repaired. Thanks in advance.
