Have a 2013 2104 minilite. It hase a Cavagna auto change over. The instructions say the the green indicators will line upto the tank in use and the empty or backup will be red. Problem is both ofthe tanks show red even after being switched. Both tanks are at least 3/4 full. How can i tell which tank is being used? Do I have to have a lp appliance lite and or for the green to register?
