A couple of converters depend on a resistor to control the voltage to the 12 volt dc system and the onboard batteries.
Rv converter not charging battery.
Sometimes a buildup of greenish or white corrosion can get to a point where the batteries can t receive a charge or receive a minimal charge.
Batteries also charge when the motor of your motorhome or tow vehicle is running or when you re running your.
Check the resistor voltage with a multimeter and see if it s in a suitable range or not.
When your rv is connected to an electric outlet the batteries charge.
Charging a camper battery through the converter.
If your battery could be fully charged the resistor is probably the culprit here.
Or you can even put the vehicle into shore power for around 8 hours.
Even when the rv is not in use keep charging the battery.
If you do not have an inverter with this capability your conventional converter charger will recognize the battery is at 10 5 volts and throw a 13 6 volt charge to the battery until it reaches 12 6 volts and shut off.
It might not even be a true technical fault.
There are a few ways in which a battery can be charged using the converter.
Most often though battery capacity depends on the type of charging cycle you conduct prior to operation.
It should be energized whenever the rv is connected to shore power or a generator you will hear it click when it senses the power come on.
It s best to remove the batteries when not in use and store them in a dry and cool place to recharge.
Any type of breakage in the system may cause the battery not to charge.
If the battery is sulfated it will draw down to 11 volts very quickly which would make the co detector chirp.
Another cause why your rv battery won t charge is that there might be a broken wire on an open conductor that is between the battery and the converter.
If it is not ensure all power has been disconnected from the converter charger.
As dave mentions there could be a few different causes if you discover a battery not charging properly on your rv.
An rv converter charger that converts the power from the grid into 12 volt dc and then channels this to the adapter is fitted into every rv.
The rig still draws out power even when you re not actively using the vehicle.
With this idea in mind dave talks about the difference between a static fill which can lead to sulfation deteriorated.
It could also be hooked up to the grid at home through a 15 or 20 amp power outlet.
If your rv converter not charging batteries when plugged into shore power you need to take a close look at the contact posts of your rv batteries.
