This pass week end I ran some test on my electrical system on my 29.5. I found that my battery charger will charge Bank one with the the battery switch in the number one or both postion. Bank two will only charge if the switch is in the both postion. Bank two will not charge in the number two postion.It seems to me that the battery charger is wired only to bank one. Is this something anyone else has noticed. Thanks Craig Cassidy One Step Up

YES
Same thing on my 310. I've just been charging both batteries w/ a single circuit. Initially thought charger was wired to switch incorrectly but changing things up didn't help. I used a meter to check voltage and got 13.2 volts on 2nd circuit but does not charge battery. Been meaning to get back to this problem but am really a poor electrician.

Same Here
I have the same situation on my 310. Apparently the charger only has one charging wire coming out and is connected to bank one on the battery switch. I spent a lot of time trying to figure out a way to change the wiring but I concluded that there is no cheap way of doing it. I keep the switch on BOTH all the time and switch to #2 only when I anchor overnight to preserve #1 for starting. Let us know if you come up with a good solution.

Multi-bank Charger
First thing is the battery charger is NOT suppose to hooked to the battery combo switch. Then you should check and see if your chargers have multi-bank capabilities or not. If they do not then you may want to look around for one that does. The Statpower units will do 2 or 3 banks. They handle all three battery types too.

Isolator
There is an isolator that can be purchased. it is rather inexpensive. It will allow your first battery to trickle charge from the first with no crossover repercussions. Email me if you want more info. Mike D

Battery charger hook-up
I agree that your charger is hooked to battery #1 based on your observations regarding the charging in various switch positions. It is common for Hunter to wire 1 or 2 charger legs direct to the individual battery legs at the switch. In that regard I think Steve's comment could use some clarification. It would be uncommon to wire a battery charger leg to the "both" terminal in the battery switch as it allows you to turn off the charger leg. It is common to wire to the #1 or #2 side of the battery switch as this makes a direct non-switched run from the charger to the battery. An exception to that rule is if you have an inverter/charger. Then the charger leg is wired to the both switch as the switch is acting as an inverter/charger selector. It is this way in our 356. If you already have a multi leg charger, you can add another leg to the #2 battery switch and accomplish what you want. Our Hunter 290 came with a three leg charger, but Hunter only utilized two legs. Since we have three batteries, we added the third leg. This is a fairly easy and straightforward process. Make sure you fuse the wire run near the battery side. If not, Steve offered the best value solution given your system. Regarding the isolator...I do not think the isolator actually works as a trickle charger. the isolator just seperates the batteries when no charging source is present and allows a charging source to charge both. There actually is a loss of peak charging with an isolator if I remember correctly. A combiner will do the same thing without a penalty, but Mike is right regarding relative cost. I think the closest thing to a trickle charge would be something like an Echo Charger, which follows the charging curve of your primary charger and directs some smaller part of the total to the second battery. Probably more information than you wanted. Dan Jonas (S/V Feije II)

Check your manual..........
My 2000 290 has the battery charger. According to my manual, in order to charge a second battery with battery charger via shore power, I have to move the red/white wire from battery terminal #1 to battery terminal #2. I added a deep cycle house battery when I bought the boat this spring. Since I've only used shore power once, I haven't gotten around to moving this wire yet, but I will soon. For now, my charging is done when running the engine. Hope this helps....

how I fixed mine....
mine was that way too! It was also screwed up when charging from the alternator. Plus i could not stand having to constantly pay attention to what position the battery switch was set to. email me to my address in the directory and I will send you a schematic of how I fixed mine.
