I have a question about the battery charger on my 2002 Sea Ray 280 Sundancer.
Last night we stayed on the boat and had the battery switch set to "both" overnight with the generator running. When we woke up this morning to head back to the marina, the port engine wouldn't crank and the battery voltage was reading 9 volts. Obviously the charger wasn't charging the batteries overnight with the generator on. I checked the battery water levels and added 7 bottles of Deer Park water to all three of them. Thank goodness for Deer Park! I was hoping that the batteries were just low on water, hence not holding a charge well. After I used my jump box to get the boat running, the alternator voltage was just around 12 v where the starboard motor was charging at 14.4 v. I think either the alternator may be going bad or that the boat's battery charger isn't turned on or functioning correctly. The ammeter on the charger was not reading any amperage reading while plugged into Shorepower or with the generator on. That's a concern.
My last boat has a ON/OFF switch on the panel in the cabin that was for the battery charger. I can't seem to find a similar switch in this boat. Is there one or does the battery charger automatically run once AC power is supplied (either by shorepower or the generator)?
Also, does anyone know if this year boat has a fuse for the AC side of the battery charger as some do? I couldn't seem to find it while looking this morning.

This is a great site, but if you don't get an answer today, check out this other site. They always seem to have an answer, and fast too.

This may be just a nomenclature problem. Look at your AC
panel.....the top righ hand breaker should be labeled AC Converter.
That is Sea Ray speak for "charger".

f you are away from the dock, start the generator and be sure the
lockout bar on the AC master is set to "Generator", then turn on the
converter breaker and you should have both AC in the boat and a
charger that is working. Check the voltage at the batteries and you
should see 13.5 to 14+ volts depending upon the state of charge in
the batteries. If you have only 12.6 or lower, the chances are your
converter is not working.

Good luck with it.
