How did you determine it is not charging? You mentioned breakers, what about the fuses?

Hard to help with such minimal information.

The fan in most converters runs only when cooling is needed so a fan shutting down isn't necessarily a problem. More info on your batteries and converter would help us help you.

Probably connected the battery wrong and opened the reverse polarity fuses.

Kyle, you do realize we have no idea what you are working on? Type of RV? brand and model of converter?

Tell us exactly what steps you have followed, what you have tried and the results of those attempts.

Not knowing what converter you have, I can say that the fan is often temperature activated, if it isn't hot why would the fan run?

The first thing is to clean and check all your connections including grounds. Make shure the batteries are hooked up in parallel. + to + and -to-.
Check the output of the converter with a meter and see what it is putting out. Look for circuit breakers on the converter and re set them.
