House batteries not charging from shore power.
Hello all, I have a 1995 Winnebago Brave. I have read several posts and threads regarding this question-Google searches. They are all pretty old posts. I've read through a bunch here. There are so many and after 4 pages of threads, I can't find exactly what I want. My house batteries are not charging when plugged into shore power, down to 3.5v or so. ? I already put in a new solenoid. Charges when the engine is running. Immediately after running the engine for just a min or so, the volt is over 13v. An hour later, back to 3v. Any ideas? Am I grounding out somewhere and bleeding the batteries? Broken wire? Is there another solenoid, relay, or fuse that I need to look at? Seems so fast to me. It is plugged into shore power. I'll check the voltage in the morning and delete this if all is well. Help! Thanks, Dave.
