Total Nooby here. I bough at real nice set up last year and am slowly learning how everything works. Part of the setup includes a dual battery system. And please forgive me if I'm not describing everything correctly.
I had to remove the batteries recently so I took a photo of how the cables were arranged and put them all back in the same way. But now, once I take the truck into the sun and the solar panels are able to make some power, the Overcharge alarm on my National Luna Dual Battery Controller starts to go off. And the top 4 green lights flash. It'll stop, then start then finally stop after a while. I can also silence it for a bit by holding the alarm off button for a few seconds. But it starts again.
First, I don't want to damage my battery and second, it's annoying. Obviously something is wrong but I can't figure out what. I'm guessing something happened when I put the batteries back. Could this be caused by a blown fuse?
Any help is appreciated. And one more thing that seems weird to me. If I move the controller to maybe get a better look at it, I hear a knocking sound coming from under the hood. It's just a single knock.
