Let me tell you how to find a battery drain problem.
Buy a digital voltmeter that has an Amp scale. (About $20.00)
Disconnect the negative battery lead.
Put the meter on the 10Amp scale. Put it in series with one lead on the battery and the other lead on the ground cable.
This will show you the battery drain in Amps. A perfect set up like your car should not be over 25MA (.25AMP) and that will be the radio memory. This is called the parasytic load.
I would pull the fuse for the interior lights so opening the door will not affect the meter reading.
Make a list of everything you do.
First take a reading with everything connected, record it. Next, pull the alternator wires including the big red one and take a reading. (One at a time)
Next pull each battery driven fuse one at a time and check the reading.
When the reading drops you have isolated a battery drain.
You can isolate shorts/drains in good order that way by disconnecting wires that control something. I have used this method hundreds of times so it works.
