My RV's House Batteries Aren't Charging

Shore power does not charge house battery's. I have a 32v Southwind 2006. It charged battery's when RV is started only. Generator won't charge battery's either.

Based on your description it sounds like your RV's Power Converter is no longer charging your house batteries. Normally when you are plugged into shore power or running your generator; the RV's Power Converter will take over the task of providing 12 volt DC power to your RV as well as charging your house batteries. The fact that the batteries are only being charged when the motorhome is running indicates that you definitely have a problem with the Power Converter and it may have to be replaced.

If the Power Converter needs to be replaced; you should have a Certified RV Technician perform the repair. But before you take that step: here are a couple of things that you can check to troubleshoot the problem.

1. In the electrical compartment of your motorhome you should check for any blown fuses or tripped circuit breakers.

2. Inspect the Power Converter itself for any loose. broken or corroded connections.

3. Inspect the house batteries for any loose, broken or corroded connections. Just a tip here: since you are inspecting your house batteries this would also be good time to also check the electrolyte levels in the batteries and top them off with distilled water if needed.

4. Check the wiring coming from the converter to the house batteries for any in-line fuses that may have been blown.

If everything mentioned above checks out then it is time to take your RV in and have a Certified RV Technician diagnose and repair the problem.

I hope that this information has been helpful to you.
