Hi everyone, new to the Class A world

Here is a link to "the 12 volt side of life". It sheds a lot of light on the RV electrical system. It is really not that complicated. Do you know if you have an inverter? The inverter changes 12 volt DC to 110 volt AC and you can run a few 110 items like a TV from your Coach/or house batteries. Let us know after you read 12 v side of life if you have any questions and you will get many answers from the forum. Don't ask to many subjects at a time, just one or two at a time and you will get more answers. Then ask a couple more later. Good luck. Get a good multimeter to make your measurements instead of guessing if you have a good charged battery, first place to start, you need a fully charged battery.
