Kellys,
Could you post the brand/model number of the unit you presently have, and is the converter/charger separate from the Load Center or mounted to the back of it? This info will be helpful for replacement considerations.
I assume you have checked for any blown fuses, faulty breakers, loose wires, etc., at your Load Center and Converter/Charger.
Back in 2006 in most cases Jayco used the IOTA brand converter/charger which were only 2-stage chargers, now 3 & 4 stage are more common providing enhance battery charging.
Progressive Dynamics offers great, reliable converter/chargers. Personally I would stay away from the WFCO brand converter/chargers.
Here's a couple 'non-active' JOF threads that pertain to older Jayco converter/chargers that may be helpful:
