The float is just that. It floats the batteries at about 13.7volts with only enough current (amps) to offset the draw from the system. Do you have 21 amps of 12 stuff running? Thats a heck of alot of current, unless you gots all the lights on, furnace etc etc. Turn everything that is 12 volts off and see what you get. It should only be a few 10ths of an amp if the batteries are already charged.
