Battery Charger Not Charging

I'm beginning to believe that my battery charger is not charging. I have solar panels so I have more power than I know what to do with during the day and I live on a mooring so I'm rarely plugged in to shore power. When I am, my outlets work and my water heater works but I wake up in the morning and my batteries are not topped off (at least according to the solar controller). I sometimes hear the cooling fan go on at night.

The unit is inside my chart table so it's hard to get to but when I take off the vent cover I can see that the "ready" and "charging" LED's light up but I don't see the current LED's light up except when they cycle during startup.

I've read that there are fuses inside the unit but I would have to get it out from inside the chart table and disconnected to open it up so before I start ripping out furniture, I'm wondering if there are any other bright ideas out there.

The charger in the picture I believe will only come on and charge the battery when plugged into an AC electrical source like from shore power or a generator

Sorry I misread your post, I thought this was only happening when you are on a mooring ball......So when you plug into shore power and flip the switch for the battery charger, you dont see an increase in battery voltage? Your issue is most likely the charger. When we bought our boat we had the same issue with a Xantrex charger. It would come on, charge the batteries for a while and then stop...The problem became worse and finally it would not turn on at all......I replaced the Xantrax with a Pro-Nautic and it has been working perfect for 4 years. Im not sure how old your charger is but it may be bad...You might just check and make sure the charge cables from the charger to the batteries are in good condition...These chargers also like a well ventilated area. At least as well ventilated as we can get them.

I'm going to pull the panel and make sure there's not an in-line fuse I've missed somewhere but I'm guessing this is a 1990's installation at best along with a matching inverter which is rarely used.

Next question is how do I get the old one out of there? It's in the space under the chart storage between the kick panel of the chart table and the back of the dinette. Anyone ever done this surgery?
