![]() The air conditioner runs off AC, but the voltages that power the thermostat–which is 24 in a regular house, just 12 in an RV–it killed the 12-volt power, killed the thermostat and shut off my air conditioning. My blue converter is connected only to appliances and things that need electricity and so my converter is completely isolated, safe for me to take in and out and that’s what I did. Now on the right hand blue arrow, that breaks that connection. That’s convenient for a lot of reasons, but in particular it was convenient for me to take the battery off line. I rotate it from the on position to the off position. What I like to do next is, I’m fortunate in my RV that Open Range actually thought ahead and put in a battery disconnect switch. You should have respect for AC too, but a lot of people don’t have any respect for DC. 12 volts, these batteries got a lot of power in them. If you connected a wrench from the positive side to the negative,one, it would get spectacular, but it can even melt things. I really don’t want a battery hooked up to stuff while I’m working on it. This is almost embarrassing, but I\’m trying to tell a story, and I didn’t stage this like I could. In my RV, the battery is in this picture. ![]() ![]() Next thing, let’s just talk about the battery. What that does is that eliminates the path between the fuse box and the converter where the blue arrow points. Once I found the mark and know that’s the breaker, you just move the breaker to the off position in this direction. Open range marked this which is my manufacturer, not me. First thing you’re going o do is to look in the fuse box, or your breaker box, and you’re going to look for something marked C-O-N-V. Honestly, it sounds more spectacular than it really is. It sounds, Oh my gosh, I need to be scared of this thing. This is the part that this article is about and that is converting the blue lines, AC, power plant style power, to the red lines, which is battery-style power. You can do an awful lot with just a battery on an RV. Then on a lot of your systems on your RV–your refrigerator, your thermostats,your lighting, your igniter for your furnace, your igniter for your hot water heater–all those things use battery style power. The battery-style power, which is called DC, goes from the converter to the battery. It\’s available for you when the electrical system isn’t hooked to power. The battery in an RV will store power chemically inside the battery. A converter then, needs to work with a battery. This is a picture of the converter I’m going to put into my RV that fixes the bad converter. AC power goes to a power converter, you see that blue line is touching the power cord in the converter. That AC power goes into the fuse box for routing to different places in the RV that still take AC power. Now, keep in mind at this point, its power plant style power, and if you’re going to be an expert, that’s called AC power. It eventually gets to a 50 amp plug, which goes into the RV. First off, power roars around the United States and Canada and wherever you might be, but in my case, it’s United States,and more specifically Texas. It was my power converter.īefore we got too much further, in case you’re not a converter expert, I think I’ll tell you what I learned. When I looked underneath the stairs,I found my fuse box and my breaker box. I thought I had a rattlesnake underneath my stairs. Then from underneath the stairs I heard a rattling noise, a buzzing noise. When I woke up that morning to get me some delicious drinks from the refrigerator, the light in the refrigerator was dim. If you want to know how to do that cool effect, call me. How did I know I had to replace it? Well, my lights were flickering. If you think about it, I replaced the entire DC power converter system. Just recently I had to replace my RV power converter. ![]() The article features a Progressive Dynamics Power Converter and there is a link to this and other converters at the end of the article. Perhaps you might save the money that you would have paid out for a professional repair or a replacement fitting. It is not as difficult as you might have thought, especially on a fifth wheel. In this RV servicing article, you will learn the basics of RV power converters, and be told the steps to replace a converter. A how-to article that the all of us can use. ![]()
