Bad Power Supply Converter/Charger?
I have a Parallax Power Supply brand name converter/charger in my 2008 Cruiser RV Fun Finder travel trailer. I recently installed a brand new fully charged RV battery per my repairman's recommendatio...

9V measured from a wet cell battery usually indicates the battery is deceased. If you brought it back to a full charge, that is really a good deal.
To diagnose whether the converter is outputting a charge, you can measure the output, either/both across the battery terminals or at the distribution panel. It should be 13.5V->14.5V. If the output measures the 13.5V but across the terminals you don't measure very close to that, there is a problem with the charging circuit. This can be as simple as corroded wire connectors or more complex like a tripped circuit breaker. If you do find that the converter isn't outputting any charge voltage, there may also be blown fuses. Sometimes these are internal to the converter and blow because of a reverse polarity condition, i.e. someone attached the cables to the battery backwards.
Hope it's an easy fix for you, good luck.
