I get in my car to start it this morning and my car battery is dead again after i JUST installed a new one. My alternator is fine because once the car is started it runs at a cool 14 volts. When the car is off I hear some fan always running in the left of the engine bay... that could be draining the battery

 

Might be the fan yes i have heard alot about this problem on old model Honda and Acuras and it's usually a relay switch or a bad connection that keep's the fan's on. try and see if u can see the wires and see if they are exposed and touching a other power source but i highly doubt it.Usually it's the relay's.
