I have a Sea Ray
Sundancer with 4 new batteries. When I fired up the engines last week I noticed a lack of energy in them and the meter said they were all at around 50%. The boat is docked with 30amp service
. I was able to get the engines started and we ran them at least 4 hours and the batteries did not charge. When arriving back at the dock
we notices the wing nuts were loose on 3 of the batteries and we tightened them hoping that was the problem. We hooked up to dock
power and let it sit a week. Today I arrive back at the dock and they are still at 50% or worse.
Any ideas? Simple as a bad charger
? Do the engines go through the charger
to charge the batteries?
