Hey guys, I have an 07 240DA and I have it on the trailer next to my house. I accidentally killed battery number 2. So, what I did was hook up the shore power cord and used an adapter to plug into an outlet to my house so I could use the battery charger to charge the battery back up.

The problem was, when I hooked it up, I did not see the green power light come on on the distribution panel. I reset the main breaker and now the light on the shore power cord does not light up anymore. Did I do something wrong?
 
Are you plugged into a GFI outlet from the House?
 
I have shore power cord connected to an extension cord then into a surge protector. Now, the shore power cord light is on, however, the green light on the main distribution panel is not on.
 
Are you sure you don't have a reverse polarity problem? I run my shore power off an adapter at home and it works fine. What type of breaker is the house outlet on? Do any of your outlets on the boat work? Does your shore panel show what type of voltage you are getting?

I am getting no reverse polarity nor power light on. I also have no voltage as well. The only light that is on is on the shore power cord. So, basically I do not know where to look.
 
Did you check the main breaker in your transom trunk?
 
Give me the most idiot award, I actually had the breaker off and I thought it was on.


One more question, do i need the battery to be turned on in order to charge the battery via battery charger?

Right now, If i try to turn the cabin light on, it wont come on while it is hooked up on shore power. Does this mean that I drained the battery?
 
Good question - will batteries that are switched OFF will still take a charge? Someone here would know the definite answer to that. I would think the will charge, but it's easy enough to find out with a multimeter.

Even with a pretty dead battery, if the charger is on, your DC interior lights should work, but you need the battery switches to be on for the lights to work.
 
I'm don't know for sure how the 240 is wired, but I know for sure that my '98 330DA, '02 380DA and '03 410DA all had the battery charger wired so that with the battery switches off, the charger still charged the batteries.

My guess is that your 240 is wired the same way.
 
I always shut the battery switch

on my 2002 26' Crownline and left the inverter on, and the batteries remained fully charged. I never shut the switches on this boat so I couldn't say.
 
I shut my battery switches off just in case I, but more likely the admiral or guests, left anything DC on.

Bilge pumps are direct wired, so no worries there. One caveat, and I found this out the 'hard' way, is that SHOWER SUMPS are also direct wired to the batteries. So if you have a stuck shower sump, shutting the batteries off won't kill power to them.....at least that's how it's wired on the 410DA.

They DO charge when switch is off.

You need the switch ON for the DC lights to work. Regards and see you around Elliott Key or Key Largo!!!
 
I know when they added the shore power to my 240SD and I had them install a charger. It did not mater how the battery switch was set. Both batteries would charge at the same time.
 
The batteries do not have to be "on" to charge them with the built in charger. Try the light with battery 1, then 2 and that will give you a quick indication. It is true that if you run a flooded cell too low for too long it may not "accept" a charge.

Some newer batt. chargers installed on Sea Rays (Meridians and other brands too) will not charge batteries when voltage on batteries is too low. I think chargers circuit assumes that battery is bad and will not start charging. The trick is to connect booster jump box to dead battery and charger instantly will start charging :)
When charging deeply discharged battery I would recommend not to turn on lights for at least an hour or so. Charging current plus current drawn by light bulbs may exceed current allowed by charger internal fuses and you may need to replace blown fuses.
