House batteries not charging
I had an issue on our 5300 mile trip out west that we just got back from last week. I wanted to share what happened and how I fixed it just incase any of you run into the same situation.
Our house batteries got to where they would not hold a charge. When I would unplug from shore power or turn off the generator the refrigerator would almost immediately start beeping and read LOW DC. I just replaced all 4 house batteries last summer.
I immediately logged into here and did a search to see if anyone else had had the same issue. The post I read said to look for a ground wire on the rear of the chassis that sometimes comes loose because a screw head breaks off. Well evidently that had happened to the previous owner, because it had already been fixed.
With all the crap that breaks on these rattle traps, I come well prepared when I head out on a big trip. Lord knows what will break around the next corner. I had my ohm meter with me. I disconnect all the batteries from one another in a rest area and started checking voltages. 12.4....12.5....12.3.....11.2 BINGO. Mr 11.2 voltage battery I assumed had a bad cell. I stopped by an ORielly in Wyoming, replaced the battery and now all if fine. I guess that one bad cell was killing the whole battery bank.
Just letting you guys know what happened, just in case it happens to you.
I try to wave at all the Seneca's I meet out there on the interstate. I roll a lot of miles, so you'll eventually meet me. If you need help, I have a big tool box with me....LOL.
