As I reported in the last post, we had another episode of battery death, this time with our brand new 150 amp-hour batteries that we just purchased last week at Camping World. At the time of that post, we had let the generator run all night to try to recharge the batteries. Here’s what happened next.
When Andy got up, we shut off the generator and checked the batteries. Still nothing. Everything was dead, and they were not being charged from the generator.
Next we tried charging them from the alternator while running the engine (the batteries normally get charged while we’re driving the RV). That didn’t work either.
We checked the fusebox again, and didn’t see any problems with the fuses or breakers. At this point, we were starting to think it was a problem with the converter (the system that converts 110 current from the generator or shore power into DC current to be stored in the battery). However, since all the 12-volt systems in the RV were completely offline, it was just exactly as if the battery disconnect switch had been flipped, even though it had not been. And THAT reminded us that there was another fused breaker hidden underneath the big pantry drawer below the stove.
In order to reach that breaker, you have to empty the drawer and then remove it from its tracks to gain access. Once he could reach the breaker, Andy pressed the tiny reset button, and…
All the 12-volt systems were back online! The battery was still weak, registering around 11.95 volts as I remember, but at least we knew why the batteries had not been charging…they were in effect disconnected from the system.
We immediately fired up the generator and let it run for a couple of hours, and then checked the batteries again, and found that they were indeed charging and were back to a safe reading of 12.95. And since we needed to run the generator in the evening so I could use the Instant Pots for dinner, we kept the batteries topped off at 12.95.
The next test was to see how well they held up overnight with the furnace blower running, as well as the other minor draws on the system. When Andy got up this morning and checked the batteries, they read about 12.19, or about 60% capacity, which was acceptable. We ran the generator for a little over an hour this morning, and by then the reading was about 13.1, so we’re feeling great about that.
Our best guess of what happened is that when we failed to run the generator on Tuesday morning based on the reading on the stupid control panel, the batteries drained to the point that it caused the disconnect breaker to trip when we turned off the generator on Tuesday night to switch back over to the 12-volt system.
So we’ve learned some valuable lessons in the last two days:
- We cannot rely on the factory-installed battery meter to monitor the available charge on the batteries. Instead, we are now using the multi-meter to get the exact voltage, even though it’s a pain to have to open up the battery compartment (located under one of the entry steps) to use the meter. We check it several times a day. At some point we’ll probably look into having a proper battery meter installed that displays the voltage at all times.
- We will always run the generator at least twice a day to keep the batteries topped off, unless we’re driving the RV, in which case they’ll be charged from the alternator.
- If the entire 12-volt system goes dead, the first thing we will check will be the disconnect breaker under the kitchen drawer.
So Andy called Camping World in Tucson to cancel the service appointment that we had scheduled with them for 8:00 AM on Friday. Turns out they didn’t even log the appointment so they wouldn’t have been expecting us anyway. Funny how that all worked out.
Tomorrow we’ll be picking up our new solar panels and Kodiak generator at our friends’ house in Phoenix. They were kind enough to let us have the equipment shipped to their address, and we’re looking forward to getting to visit with them for a little bit! While we’re in Phoenix, we’re also going to have lunch at one of our old favorites, Green New American Vegetarian restaurant on 7th Street. They have an extensive vegan menu, and we can’t wait to chow down!
We have also made our plans for Christmas. We’ll be leaving this beautiful BLM campsite in the Cactus Forest on Thursday of next week (sad face!), and we’ll travel to Glendale where we have reservations at an RV park for six nights. It will be nice to have full hookups again for a little while–unlimited showers, laundry facilities onsite, sewer hookups, electricity, and wi-fi. We were fortunate to get a site in this campground on our Passport America membership at half-price, so the six nights will only cost us $117, which is awesome! We’ll stay there through Christmas Day, and then pull out on December 26th for destination still to be determined.
In the meantime, I’m continuing to hunt for geocaches, finding my fourth one this morning. The ones that I’ve found are all located just off the road so I could have easily driven to the spot and saved some time. But I’ve picked up this hobby primarily for the exercise, so I’m hiking through the desert to each of the cache sites, burning off some calories and seeing some beautiful scenery.
If you would like to know more about what geocaching is and how it works, check out their website at Geocaching.com.
Yesterday we made a quick trip into Marana to ship a Christmas package to my parents and pick up a few grocery items for our salads. While there we also had lunch at Chipotle (the sofritas bowl rocks!!) and later some ice cream at The Screamery.
So that’s what’s been going on around here…just enjoying some blue skies, comfortable temperatures, and fully-charged batteries!! Our next big challenge this weekend will be learning to use our new solar system so we don’t have to run the generator so much to keep the batteries charged. Free power from the sun!!
