Keep in mind both the converter and the battery feed the same point in the 12VDC Power Distribution Panel where all of your 12V FUSES are located...
I would pull the negative battery terminal and turn on the shore power and if your ceiling are working normal then the converter is working...
It would be a better test using a mulitmeter because you really want to see around 13.6VDC coming from the converter/charger unit when shore power or generator is ON...
After it has been all dried out and no more visible water anywhere it may work just fine if it survived being initially working with water pouring on it... It should not start any fires if bad - it will just trip the 15A Circuit breaker it is plugged into...
I test my DC system all the time at the battery terminals using a mulitmeter. With no shore power turned on I will read 12.6-7VDC across the battery terminals if the battery is fully charged up. Then I will turn on shore power or start up the generator and I will read 13.6VDC or higher depending what charge mode the converter/charger is doing at the same battery terminals. With my PD9260C charger it may go as high as 14.4VDC... This tells me the converter/charger is working normal and all of the fuses and battery connections are good between the converter/charger and the battery Terminals... Multimeters are cheap from the Auto parts stores-Walmarts-Lowes etc... $6 to $15... A must have item in your RV tool box IMO...
