I could really use some help....
Do you own a volt meter? You can measure the voltage at a light bulb when connected to the shore power. Any voltage over 13 volts means you converter is working. Measure the voltage at the battery and if less than 13 volts you have an "open" between the converter and your battery.
There are two "current limiters" between the battery and the converter.
One is very close to the battery (perhaps behind the battery box) and one is located very close to the metal box your umbilical plugs into (mine is right next to box, under the pin box attachment).
They are usually covered with a red rubber "cap." There is a push button reset on one of the short sides as indicated.
I attached the manual for the most common 30 amp WFCO power center with 55 amp DC converter. Your panel may be the 50 amp power center and the converter may be the 70 amp version.
If you have the model number for your power center I most likely have your manual.
Multi stage chargers take "a lot" of time to fully charge a large battery bank due to the deep capacity that has to be replaced and the requirement to "step down" the charging rate to prevent "boiling" the batteries.
Charging faster IS possible with a dedicated battery charger BUT the faster charge rate will damage the battery over time and reduce the number of possible recharge cycles available.
