| Post subject: | Battery not charging on generator |
Yesterday we spent the better part of the day rafted up with friends. The weather turned bad so I put up the camper canvas and we rode the storm out. Since we had been out for a while I knew the house battery was probably getting low so I turned the generator on an my wife did some things in the cabin. Turned out the storm lasted quite a while so the generator ran for at least a couple of hours. We broke from the group and motored to a quiet cove for dinner and I again ran the generator for at least an hour. I have a meter and noticed my house bat was way down. The weird part in all of this is while the generator was running my house bat did not seem to be charging. I initially showed 13 volts but the meter quickly dropped to 9 volts showing me the house bat was still dead. Any idea why I might not be charging while the generator was running? Yes I did check the breaker switch for the charger and it was on. |

Does your battery charge when you are on shore power? The battery charger doesn't know the difference between shore power and generator power. Maybe the battery charger is broken and you've been charging with the alternators. Can you see your charger, while running on the generator, mine has a meter. Did you check all the breakers. There is an AC breaker on the input to the charger and there should be a breaker for each battery bank on the output of the charger. Did you have the battery switch on? Some boats only charge with the battery switch on. Maybe the batteries are going bad. |

Does anything else work with the generator. There is most likley a breaker on the generator itself, coupld it be tripped? Does your boat have a transfer switch? was that in the correct position? |

Thanks for the suggestions. I need to inspect this problem more closely the next time I am out. The batteries are charging fine on shore power but don't seem to take a charge if the generator is running. I spoke with one of the guys we were rafted up with and he suspects a loose connection. I did have this happen late in the year last year but it's the sort of think you don't notice until the battery runs down and then use the gen to charge. This weekend I plan to remove all of the connections to the battery and inspect them. I think I will try to duplicate the problem under a more controlled circumstance and see if I can narrow the problem down a little more. I'll let you all know what I find if anything. I would think that running the generator for two or more hours would at least put a halfway decent charge in the battery. Next time I'll time it and put my meter on the battery to see what I'm getting. |
