If you are draining the battery, then there is no charge getting from the alternator to the battery. The car is running solely off of the battery,

Did you have the alternator output checked? And if the alternator is working properly, is the charge reaching the battery? Obviously not.

Mine had a similar problem. Gauges would refuse to work while running, car wouldn't start unless jumped, fan wouldn't even come on at all. The wire to the alternator had broken at the atachment post. Drained two batteries until I found the broken connector.
