Re: CO detectors sounding alarm
Check your connections. They must be tight and clean. Check them at the batteries, at the charger, and behind the battery selector switches if applicable. If the charge wires go through breakers, check the connections there too. If the ground wire from the charger goes to a ground point other than the battery such as the engine block, ensure the ground connections at the blocks are clean and tight as well.
Ensure the charger is set to the correct battery type ie; flooded, AGM, etc.
If your battery cable or charge wire insulation is discoloured (usually close to the terminal lugs/connectors), it has overheated and could be causing a high resistance.
Do you have a diode battery isolator? If so, the charger should not be connected to it (have seen this a few times). You could use the isolator as a connection point but it must be connected on the battery side of the isolator, not the alternator side.
All the above will boil batteries.

Re: CO detectors sounding alarm
bud37, I thought the same thing about the fridge and will pull it out and see what is connected to what. The refrigerator was replaced in 2011 so it is not that old. I will also check for a GFCI fault causing the fridge to stay connected to battery power all the time.
tomschauer, No inverter on the boat. The new battery charger is not connected through the individual 3 bank circuit breakers yet. I do have power and ground wired to the original circuit breaker for the battery charger. So each battery is connected directly to the battery it is charging. I have not turned off the DC circuit breaker panel at the helm but will try that this week also. Good idea disconnecting the batteries from everything on the boat except the charger to see if they will charge.
I did load test the batteries and they are all showing good on the load meter.
Viper, I did have the Perko set to BOTH and like you said, that probably killed the new battery but then replaced both batteries again. The new charger is supposed to automatically check, analyze, charge and maintain each individual battery but I realize that even a new piece of equipment can be bad. The charger will also work with multiple mixed battery types and charge accordingly. I have checked and cleaned connections, grounding points and disconnected and tested loads on items that are always connected to the battery bus even with the Perko selected OFF. The fridge is one of the things I hadn't thought about until I started searching the Forum for answers. No diode battery isolator that I know of.
My buddy brought up a point that might take the new DC system out of the equation..... Whatever is pulling down the batteries and forcing the charger to be in a constant charge mode was what prompted the new batteries and charger. He thinks it is a existing problem that was not corrected with the new DC system components. That also makes sense to me but I have to try all of your suggestions until I find the culprit.
As a side note, the only thing that has stopped working since the problems began was the starboard fuel sending unit. Also, am I correct that stray voltage and galvanic corrosion could not be drawing power from the DC system causing a constant charging of the batteries?
Thanks for the help.... keep it coming.

The charger will not maintain each individual bank separately if you have the selector switch on BOTH. By doing that, you're combining the two banks into one. The charger will see this as one battery, not 2 or 3 individual ones. Further, if one battery is a deep cycle and the other is a starting battery, by setting to BOTH, you're combining and charging in the same bank, two dissimilar battery types.....a no no.
Check and ensure there are no bare wires or connections sitting in bilge water, usually the case with bilge pump/float switch wiring. This will cause power drains.

Re: CO detectors sounding alarm
Typically isolators are used to charge multiple banks from one or two alternators. Since the typical charger is capable of charging multiple banks while maintaining bank isolation, you don't need an isolator for them. Having said that, you can incorporate an isolator with your charger if you add an additional battery bank but have no spare charging legs left on the charger. Caution is required here though to ensure this is done properly. A good example would be a 3 bank charger hooked up to each of two isolated engine batteries, and the 3rd leg to the house bank. If you decide to add an additional isolated bank dedicated to a thruster or sensitive electronics for example, a practice that is becoming more popular, you'd need a way to charge the fourth bank while still maintaining isolation from the others. You can change the charger to a new four bank unit, or purchase an additional charger, or add an isolator or ACR to one of the charging legs for the forth bank.

Viper;
Thought I saw 3 separate feeds coming off the OEM ACtoDC charger to the three OEM batteries in this year and model Carver, leading me to believe that they were all being treated independently. I'll have to do some diagram research this season with the paperwork on the boat on this. Our boat has alternators on each engine. I assume each engine has its own battery. If I run on just one battery with both engines running only that engines battery registers on the dash volt meter. When I'm running in the both position on the battery selector switch, both dash volt meters register? Thus leading me to believe they are independent of each other? Mike
