The RV battery has to be kept in good shape for it to power the vehicle.
This creates a situation where you are not going to want the RV battery to start dumping power as you drive. It’s important to have a setup in place where it is going to work as you want it to and nothing will get ruined.
One of the concerns people report has to do with the RV battery not charging while driving.
If the RV battery is not charging while driving, the most likely issue has to do with a loose or damaged wire between the tow vehicle’s alternator and the RV. Check the wiring, replace any damaged wire, and then re-test the connection.
This is going to help restart the connection and get the RV battery to where it needs to be.
This guide is going to help you take a look at how to fix an RV battery that’s not charging while driving.

How To Fix RV Battery That’s Not Charging While Driving
1. Check Wiring Between Alternator And RV
You will need to be sure about the wiring.
This is one of the biggest issues people deal with when it comes to keeping the RV running as it needs to.
You will have to see whether or not the connection between the two vehicles has been compromised. If there is any damage to the wiring, you are not going to get the RV battery to charge properly.
This will begin to impact everything including how the RV air conditioner works or how the RV runs during the day.
You will want to take a look at both ends.
This is going to include the plug for the RV and also the wiring running into the alternator. This is going to let you take a look at what is going on and where the damage is.
2. Check The Voltage At The Terminals
Have you taken the time to look at the voltage at the terminals?
This is a good point to think about.
You will want to make sure there is enough voltage at the terminals. It should be offering at least 14 volts of power as soon as you connect to it with a voltage reader.
This will let you know if the voltage is on par with what you require.
If you don’t take the time to look at the voltage, it might not work as you want it to. You have to make sure the voltage is running through at the terminals as that is how the RV battery is going to charge properly.
3. Inspect The Alternator
You will also want to think about the alternator.
The alternator becomes a real concern if you are not careful.
You will want to take the time to see how the alternator is doing and whether or not changes have to be made to the tow vehicle.
Sometimes, you will assume it is the writing that is the issue when this is not the case. Instead, it is going to be the alternator that is starting to fade or lose its power.
Look to see if the alternator has to be replaced.
If the alternator is not working properly, the RV battery is not going to charge as you drive. It will simply not work.
This is also going to put an additional load on the RV battery.
4. Restart The Vehicle
When you have taken the time to look at the various connections, it’s best to restart the vehicle.
This is going to help reset the connection and ensure power courses through as intended. You will need to go through this trial and error phase to make sure everything works.
Do not rush this process.
If the wiring was damaged, you will need to replace it. If it wasn’t and the wiring was loose, just tighten it and you should be good to go.
For any task where you want to optimize the connection, you can look at using a separate battery charger for the process.
This is not required but it is one way to get more power to the RV battery while you are driving.
These tips will help when the RV battery is not charging while driving.
If the RV battery is not charging while driving, this means the connection between the alternator and the RV is loose or damaged. Inspect both the connection and the alternator to see if something has to be changed or repaired. Go through these steps and then restart the vehicle.
This will help reset the connection.
You have to be thorough while inspecting the connection as you could end up damaging the alternator and/or RV battery during the process.
