Why are my motorhome batteries not charging?

If your camper trailer battery is not charging, the way to troubleshoot is to check for corrosion, battery charge health, and converter issues. Your circuit board may have blown fuses, diodes, and resistors, or the shore power may be at fault. Proper maintenance is the key to battery health.

Can you leave an RV plugged in all the time?

You can leave your RV plugged in all the time while in use or for short term rentals as we’ve discussed. Long-term use and storage are only possible if you use an RV battery tender or have a newer RV converter with a smart charging system to maintain optimal voltage.

Why does my RV battery charge every time I plug it in?

Every time your RV is plugged in, your house battery gets charged. Whereas it is just a trickle charge, it may deplete the electrolyte levels of your battery cells. And so, you are supposed to maintain as well as check your battery on a monthly basis when your Travel trailer or camper is plugged in for instance while in storage.

What does it mean when your RV won’t start?

The RV won’t start. There are none of the typical dead battery behaviors – no clicking, no lights flickering, nothing. All of my normal dash lights do not come on when I turn the key. Even the radio light is out. When I flip the chassis battery disconnect switch it springs back into the ON position and won’t stay off.

What kind of Charger do I need for my RV?

An RV charger/converter that converts power from the grid to 12-volt DC and after that directs this to the adapter is usually fitted to every RV. Batteries as well charge while you are running the generator or when the motor of your tow vehicle (or motorhome) is running.

Why is the battery on my RV not charging?

If you check the batteries with a multimeter or voltage meter an hour later, they should still give you the same fully charged reading. If the voltage numbers are going down, then it’s likely a battery problem. Most of the time you will need to replace the problematic battery.

Why is my AC converter not working in my RV?

Sometimes the shore power source from the RV pack can be the problem. Check the power post to make sure there aren’t signs of a burned-out outlet or some other fault. Sometimes something as simple as a bent prong or damaged outlet can prevent delivery of the AC electricity to the converter itself.

Why does my motor home not turn on?

“Not even dash lights when I turn on the ignition (with 12.7 VDC) suggests either a bad connection between batteries and dash OR a bad IGNITION SOLENOID. Start by verifying voltage at the chassis battery side of the ignition solenoid. Then with key on, that you also have voltage at the “far side” of the ignition solenoid.
