Expert Reply:
If the Converter # PD4645V for your Parallax 7300 is converting power from 120 volt to 12 volt but your battery is not taking a charge you will either have a wire damaged/disconnected wire or the battery needs replaced. Depending on the age and condition of your battery it may not be able to take a charge. You will typically have to take your battery out to take it to a auto shop to have it tested. We do carry a Battery Charger # MA57JR which you can use to attempt to charge the battery at home and it will also inform you if the battery is bad. It also acts as a maintainer to keep the battery at optimal performance when your camper is not being used.
The other issue could be a disconnected or damaged wire. The easiest way to test this is by using a Multimeter # PT89ZR to measure voltage at the converter and at the battery. Depending on how long the wiring is between the converter and your battery you will likely see a slight voltage drop. You should see 12.6-13.6 volts out of the converter and at the battery. If you see a large drop from the converter to the battery you know there is a wire not connected properly somewhere or a wire which is damaged.
