Fleetwood jamboree charging system problems

First camping trip of the year in central New York. Plugged in to 110 power. Charging system keeps ramping up and down. Stops. Starts. 12v lights keep brightening and dimming as the charger goes on and off. Coach batteries were new in spring of 2014. When on getting 13 v at the battery. Anyone have an idea what we need to check next?
