    Sterling regulator

    I read this recent article by Niger Calder about Sterling regulators. One of the big mags. Who would have thought? Essence: don't go fancy on alternators or batteries, use to the MAX what you have. As usual great writing. I did a bit of searching in the archives, but nothing popped out...

    Battery Health--hydrometer, plus potential starter motor isssues

    I use two Trojan Group 27s for both house and starting. Lately one battery turns the M25 over with less oomph than the other. Both batteries were installed by the PO in early 2012. When on the Xantrex Truecharge2 40A charger, Hydrometer readings on Battery 1 are 127 for all six cells. Three...

    E-28 Universal 12 charging question

    I just bought my E28 this July and have a charging question. WHen I first start the engine, the ammeter would only show a slight charge. Not putting too much faith in the meter, I took my analog multimeter and tested the batteries with and without the enging rumming and there seeed to be no...

    Charging circuit fuses

    My charger (Xantrex Trucharge 20) connects to the battery bank with 8 ga. wire and a 30 amp fuse is specified. The 8 ga. is much too big for a standard in-line fuse holder. Blue Seas (among others) has quite a confusing array of different fuse types. I am not sure what the best fuse holder would...

    Charging Batteries with Honda Generator ?

    This year we hope to spend more time at Catalina and visit some harbors within a day or so of Dana Point. My question is: Does it make sense to carry a small honda generator eu1000i to charge my batteries. I understand I could do this with my engine, but she is very old and tired and was...

    Battery selector and charging

    In anticipation of getting back down to the boat this weekend and tackling the alternator question I've been reading the 12-volt bible for boats. One thing that surprises me is that he seems to imply that the battery selector has to be set to "both" for both batteries to charge. Looking at...

    Battery switch during shore charging?

    I was wondering if I need to have the master DC battery switch on "ALL" or "OFF" when hooked up to shore power and charging. The Newmar charger leads go directly to the batteries (it even says right on the case to do this) so I wouldn't think it matters where the switch is. I Googled it and...

    charging a dead battery

    Does anyone know if you can charge a dead battery with a small 5 amp charger? Thanks

    Battery life and charging.

    All Having read all the threads on battery life can I assume the following: 1. I should not discharge my batteries below 50%-ever? 2. May I assume, since my boat sits in a slip attached to shore power, that the constant trickle charge will not reduce the effective life? My quest...

    Charging Voltage from alternator

    We recently replaced our older standard wet cell batteries with 430 ah of gel batteries. I have historically been very bad at maintaining standard batteries, so I look forward to getting a long life out of these with no worries. However I do unfortunately have one worry remaining. At the...

    generator not charging

    I removed and took apart the generator after battery would not stay charged. It is well built and servicable looking. It is a 12 volt 55 amp generator. The brushes look good. There is a electronic module that I suspect because there is 0 volts on the output with the engine running...
