    60 days till boating season !!!

    I have plugged in my 99 340 DA to charge the batteries. I plugged the boat in as if I was plugging in to shore power - the only difference is I plugged in to a regular 110v circuit. My question is - in the galley is my control panel. I have two rocker switches that I use to turn the batteries on - SHOULD THESE BE ON TO CHARGE THE BATTERIES? Or does it not matter?

    Also - Is there a way I can tell if they are charging? I have meters in the control panels - I think one works and they other doesn't.

    Thanks for your help!

    Both battery switches off. Turn on the circuit break switch for 30 amp bank that has the AC Converter circuit breaker. Then turn that and only that one on (AC Converter). Find the battery tender/charger. Mine was in the mid cabin behind an inspection window in the port side cabinet. It should indicate the charge. All batteries will charge whether they are turned on or off if they are factory wired to the charger/converter.

    In sum: Battery switches off. Only two switches turned on will be the AC Converter and the 30 amp bank switch to the AC Converter.

    Edit: If you are using one of those 30 amp to 20 amp plug adapters so you can plug your boat into a 110v line, I personally would make sure that plug converter connection is not on the boat. I'd run enough 30 amp line off the boat so the 30 amp to 20 amp plug adapter was on the ground. If you forget that you are not on 30 amp shore power service and start turning more circuits on, that adapter could get pushed to it's limits and get hot. Not good when nobody is at the boat and you are stored inside closely with 100 other boats. I wouldn't want to be "that guy" the marina would be talking about for the next 25 years.

    Terrific "On the Job", thank you! I think I am in good shape - Great point on the converter - I do have the 30 amp to 20 amp converter. Too much hard work has gone in to the boat to have an issue over stupidity!

    Enjoy the rest of Winter!
