    Make sure that galvanic isolator is wired right. Mine came wired wrong with the neutral and ground connected together so when my marina went to ground fault plug ins, it tripped the dock. I think I posted on this a while back.

    Thanks Ken. I'll check. I've had mine plugged into many marinas. The only one that made it unhappy was the one in Victoria, BC. Panel lit up saying reverse polarity.

    Do you have to parallel the batts to start the Yanmar? When I first got my Mack I bought new Delco Voyager batts. On a cold (by coastal CA standards) 1 batt wouldn't turn over the Cummins. The way I see it, it's not a 2 batt system if it takes 2 batts.

    I put in Yellow tops and lasted for 8 years before 1 would struggle. Recently went with Those X2's But dayum they're not cheap. $800 for 2.

    The negative for Optima (other than I've heard they moved mfg. to Mehico and quality went down and they're expensive as well) is they suffer on amp*hour rating.

    Mistress - one battery is all my Yanmar takes and it fires off before one revolution every time, except when I've run out of fuel :mad:.

    Mine starts just like Ken's. One battery and springs to life instantly.

    The Cummins lights right off assuming enough rpm/piston velocity to compress the fuel.

    I have had a Blue Seas battery panel that has separate switches for the starting battery and a breaker for the house bank with an emergency cross-connect on the Sabre for about 15 years. Also with a Yandina battery combiner. The starting battery gets charged and the house bank gets connected by a solenoid when the voltage hits 13.5.
    It is an reliable, effective, no fuss, no drama system. I use Blue Seas products almost exclusively on both boats. Top quality and real, knowledgeable people answer the phone if you have questions. When they lost their main facility and a bunch of inventory to a fire set by a disgruntled ex-employee a few years ago, I was worried about them, but they are back, good as ever.
