Battery Banks
The Prairie Schooner has 3 sets of batteries.
There’s a big engine battery: It powers the starters for the 454 engine and the 7000 kw Kohler generator, the instrument panel, and the leveling jacks.
Two other battery banks power everything in the coach. Each of those uses two 6v golf cart batteries wired in series. Originally, I used two big 12v deep cycle RV batteries wired in parallel for the coach banks, but they had a way of burning each other out and never lasted two years. One battery is always at least a little weaker than the other— it’s always going to be that way. The weaker battery calls for charging when the other doesn’t need it— which means the better battery gets overcharged and it becomes the weaker battery. Finally solved that problem by switching to the 6v batteries, which behave like a single 12v and they last for several years or more.
The last battery change out was 2000. Of course, letting the battery banks sit for 5 years didn’t do them any good. While the Schooner was sitting, I used the engine battery for something else. The coach batteries just sat and went bad. So along with everything else, it’s time for all new batteries.
The original coach batteries are in a drawer outside and easy to get at. They drive the original converter, which now no longer charges its batteries and also needs changing. That converter is located aft where the power cord comes in. This bank runs most of the interior lighting and the furnace. The furnace blower, when it’s running, has the biggest power draw.
I added a second battery bank, and a second inverter when I was traveling with my father during the mid-late 90s.
The layout of this Holiday Rambler RV has the main sleeping area in the back. The galley and head are in the middle, and there is more sleeping forward that includes a drop down bunk over the driver (only used for storage these days). For traveling with my father, he slept aft, and I took out the table and benches up forward and put in a nice fold out couch. Because the front had a lot of lights, a stereo, and my computer stuff, I decided to add a another battery locker and an inverter to run all of those. It’s a pretty good arrangement and the Schooner will have power for about a week off the grid.
Poisonous Spider!
While changing the second battery bank yesterday, I opened the access to the second inverter to double check the wiring. When I did, I noticed a monster spider! I looked it up on the internet and identified it as a Brown Recluse. One of those bit me in TX in 04′ and I had to go to the hospital.
I grabbed a paper towel, but the spider looked too big to nab like that, so I decided to use the vacuum sweeper. The spider held on for a second— then was gone up the hose. That was a relief.
Is there any such thing as just ‘one’ spider? Are they like mice: if you have one you have a bunch of ‘em? Took a good flashlight and looked around where I was working to make certain there weren’t more spiders waiting to get me. Didn’t see any. Satisfied with that inspection, I finished the battery install.
Went back and read for a while more on the internet about the Recluse spiders and using some sort of activated charcoal homeopathic treatment for the bites. Decided I would only ever try that if I had to. I’ve seen people in TX that had nasty spider bite wounds that kept coming back— one girl I knew had a bite on her butt. Two years later, the wound came back, then developed a staff infection— and with a little help from a bungling healthcare provider trying to save $, treatment was denied for just enough hours so that she ended up having to have a big part of an ass cheek amputated! No thanx! If I ever get bit again, I’m going right to a doctor like I did before.
Well, I decided enough with scaring myself reading the spider stuff. I went back and finished cleaning up the tools from my battery swap mess. Then took the vacuum sweeper out to dump it.
Dang if that spider wasn’t gone!
