I have a 1989 V6 Dolphin and I do not receive any power from my battery to run any coach lights or pump. Everything works great when on shore power, but nothing works at all when I disconnect from the shore power and run on my new deep cycle battery. Any ideas? I've read briefly about the power converter under the sofa and how that has a spring that might be stuck to only run electrical off of shore power, BUT I NEED MORE INFO ON THIS and I can't seem to find any. I'm trying to do this project on my own, as I am quite handy. Can anybody help me out with some troubleshooting or tips? Thank you so much!
