Test the transfer relay switch also called the solenoid which allows charging voltage to be sent to the coach battery.
Rv converter not charging battery.
Check the resistor voltage with a multimeter and see if it s in a suitable range or not.
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.
If your battery could be fully charged the resistor is probably the culprit here.
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.
There are a few ways in which a battery can be charged using the converter.
Any type of breakage in the system may cause the battery not to charge.
Most often though battery capacity depends on the type of charging cycle you conduct prior to operation.
With this idea in mind dave talks about the difference between a static fill which can lead to sulfation deteriorated.
The rig still draws out power even when you re not actively using the vehicle.
A couple of converters depend on a resistor to control the voltage to the 12 volt dc system and the onboard batteries.
Or you can even put the vehicle into shore power for around 8 hours.
This may be caused by corrosion or oxidation on the battery positive and negative posts.
It s best to remove the batteries when not in use and store them in a dry and cool place to recharge.
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.
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.
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.
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.
If the battery is sulfated it will draw down to 11 volts very quickly which would make the co detector chirp.
If it is not ensure all power has been disconnected from the converter charger.
Even when the rv is not in use keep charging the battery.
The camper could be hooked up to the electrical grid via a 30 or 50 amp outlet at a campground national park or state park.
As dave mentions there could be a few different causes if you discover a battery not charging properly on your rv.
