Unhappy Battery died

Ok I am not dumb by any means and now have had to replace our battery 2 times just to have lights and now heat. how does the battery charge? I have messed with the fuses, the fuse going to the battery is good and we are hooked into shore power. it went out last night and I had to use 2 electric heaters, which are dangerous in an RV. any help is appreciated. Thank you all in advance.

If you're on shore power your converter should be supplying power not the battery. Check the circuit breaker for the converter.

Measure battery voltage when on shore power. If it is not over 13 volts your converter is not working. It runs on 120 volts to produce 12 volts for charging and 12 volt loads. It will be on one of the AC panel breakers.

One of the handiest tools for diagnosing AC problems is a non-contact voltage detector, (under $20 at Amazon or your local hardware store). With it you can easily touch it against the AC connection into your converter to see if it is getting power.

If it is getting AC power you need to check the output terminals with your 12 volt test light,(under $20 at Amazon and another essential part of your tool kit). If the light doesn't go on and there are no fuses to replace on the converter then the converter is dead.

If the 12 volt test light does go on you have the task of figuring out how it connects to the 12 volt battery looking for a disconnection or bad connection. In particular check the ground connections of the battery and the converter, remove, clean and replace.

If you measure the voltage at your fusible section of your panel and it is 13+ then your converter is working. If you them measure at the battery less than 12.6 volts, then your converter voltage is not getting to the battery. If this is the case, start looking for a very small in-line square thing. Usually black. It would be on the wire from the panel to the battery. This is a circuit breaker. If you have one, it may have tripped. If you feel around the sides, you will find a very tiny button. Push it until you hear a click. Then check battery voltage. If now 13.? Then you should be good.

Check your battery charging fuse that is near the battery in a rubber enclosure.
