Not sure Lloyd. I know mine would go silent as it reached full charge but not sure if it stopped. Never looked at the converter that close. Now that I went to LED, I very seldom even hear it except if it has been discharged from sitting without power for a few days.

Fan should not run unless there is a need to cool converter. Do you have something plugged into your 12v plug? Laptop or chargers or 12v/110 converter?
It was a rainy few days at Algonquin Prov park...tarps kept us dry.

our cruiser 5th wheel did the same thing until I changed all the lights to led bulbs.
I bought them on ebay from China. They are the little square flat panel bulbs with 48 Leds
Only ran about 30.00 for all of them. It also eliminated a lot of heat that was produced by the regular bulbs.
