I just completed a 4000 mile trip with the RV and truck and had 0 problems but my 8327ss battery is running down. I metered the truck out and it is supplying 13.8 volts on the correct pin but the battery is not being charged. If i plug it up the inverter will charge it and it works fine. Is there something I can check inside that will let the truck charge the battery?
Check and find the truck charge line from the 7 pin plug at the connection above the camper's battery. It should be connected to the auto resetting circuit breaker the same terminal as the camper's (+) wire. May be a broken/faulty connector before that also.
