Take a multi meter and put the lead on the battery posts. It should read 13.5 to 14 volts with the charger on.
If you're only ready 12 sounds like the charger is not working.

If you are running an inverter the 10A that the charger puts out to each battery may be way less then the current the inverter takes out so you will not see a charging voltage.

The AC Convertor / battery charger runs on AC(dockside power or Generator)....how would that effect DC voltage ? It doesn't ! The full purpose is to charge the batteries.
If you were correct the batteries would never charge.

Yes I would like to know too as my marina is saying we are sucking too much power and the ONLY thing we have enabled is the AC CONVERTER to keep batteries charged..

Also when we turn it off (AC CONVERTER) , battery percentage drops to 98% within a few minutes , I am guessing the batteries may be on way out?

Well.....The AC converter does not put motors then 10A in any of the 3 batteries. If you plug in a 150W item into your inverter it will take about 14A out so you end up drawing 4A out of your battery and discharging it. If you plug the item you have in your inverter into a 110 outlet whole on shore power or generator you won't have that problem.

The(AC CONVERTER) has a 10 amp fuse, so it doesn't draw much. do you have your hot water heater, AC or Ice Boxes running? Never heard of a marina say that. The best way to tell if your batteries are an issue is to use a load tester.
The fact that they don't stay at 100% isn't a huge concern. Again what is running off them...Lots of DC items in a boat that pull power. do they keep dropping or hang around 98%?

Thanks for your reply.
The ONLY thing I have ON besides the convertor which is on the 240v side , is the Accessories and the only item plugged in and on is the cig lighter near the sink powering a LTE 4G modem (Dlink 5v 1.5a) for security camera, other than that nothing.
Personally I think the marina is just trying to get more money out of me.
Problem is not many options around for the same price.

I think there is a misunderstanding, the original post stated that he had an ac INVERTER running all the time, that's different from the AC Converter on the Sundancer.
To see how much juice you use you can look at the panel and see how many AC Amps you are drawing when all is kind of stationary

The AC convertor is not an inverter. I think we got the terminology mixed up. Its an AC Convertor AC to DC for charging the batteries. It does not make DC to AC. Sorry for the confusion.
 
Hello everyone in the 340 forum. I have read all posts on all 134 pages and feel that I have gained a wealth of knowledge. Thank you all for (hopefully) saving me from a dismal boating day due to ignorance and replaced (again, hopefully) said ignorance with a plethora of useful info! Happy boating to all!
 
Quick update on my battery issue from last week. Got the battery charged and back in the boat. The gauge in the cabin reads in the 13's with the AC converter on and connected to shore power. I plan to check it again this weekend when we go back.

1 interesting thing we saw when putting it all back together this past weekend. The switch box in the bilge right next to the battery charger has a switch called "accessory" and it was switched off. I wonder if that has anything to do with my issue???

I have checked the shpwer sump area and everything is dry there. There is no stains or marks of watwer coming from above atv all. I did open the compartment that is under the bottom step and the crpet in there is damp as well. Everything to me points to the Head area. Ive felt the shower drain hose from underneath and it seems dry.

The forward bilge pump is located in the aft cabin, so make sure you check there. I kept a case of water under the seat and thought a bottle broke when the carpet got wet, alas, checking the parts manual led me to this realization!

I am not clear on the function of the forward bilge pump. How would water enter that pump area? What would be the source of the water?
 
Most of the time it comes into play when your shower sump fails. The water runs back to the aft. I guess also if the any of the fresh water system lines fail or maybe a/c lines.

Imagine you had a son, and he and his buddies had a large cooler full of ice and beer, sitting on the floor in the mid cabin... now imagine that the drain plug on the cooler is not screwed in all weekend...
 
Hey all, any thoughts on a very specific area of wet carpeting in my '02 340... The carpet seems to be only damp in the starboard cabinet between the couch and the midberth. Any ideas or maybe someone has experienced the same issue? TIA!

I would look at stations and any cleats in that area. Possibly windshield gasket ?

Port light gasket? I had a similar issue on my 380, gaskets were smashed from previous owner leaving in screens and closing windows. Haven’t found the replacements yet, put a couple quarters between the latches and glass and it took care of it

My previous mystery cabin leak was a port light that wasn’t completely closed. I personally never open them. “Not me” strikes again.
 
I also had water in the floor of the back berth. It stopped when we replaced the mid-sump pump under the floor cover beside the head/shower door. I also noticed my port holes on the roof were needing to be re-caulked with a high grade marine product. No more water. in the rear-berth.
