    1974 O'Day 20 electrical questions

    I just got this boat and have a couple of questions. 1) Where was the original battery location? This one is installed on the port berth under the cockpit. It is not square and is braced by a random 2 x 4. I am thinking of moving it to the locker on the starboard side of the cockpit. Is that...

    Issues with Two-year old batteries

    My house batteries are Group 24 12-volt deep cycle from West Marine. I got them in the spring of 2017. They are serviced each fall and put on a trickle charger. As soon as I turn off the battery charger at the dock, or shut the engine down, the indicator on my instrument panel shows a pretty...

    Battery Water Level

    I had my local shop (Zimmerman Marine at Herrington Harbor North in Deale MD) replace two batteries and install an intelligent charger in August of 2016. I was told this charger should remain plugged in when I leave my wetslip to keep the batteries charged without causing overcharge issues...

    Dead Battery

    I am not a battery / electronics person. I had no issues over the winter with my (I assume) 4D batteries, but once I launched this season I came back a week later (lots of rain in the NE) and Battery #2 was in the red.

    Battery installation - Any suggestions

    I'm a brand new owner of a 2001 C16.5. Can't wait to get it in the water. I'm interested in any advice from experience of mounting a battery in the bow storage area. I'm thinking of using a plywood square cut to size, fiberglass directly to the boat (somehow?) and mount battery to it. Has...

    Recharging an old battery...

    I have an old battery - old in age, not necessarily old from use. Was a house battery, was not old when pulled from the boat, and likely saw very little draw down in its former life. It was on the shelf in the garage, and I had been okay about putting it on the charger periodically to keep it...
