Let me tell you how to find a battery drain problem.
Buy a digital volt meter 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 shouldn't be over 25MA (.25AMP) and that will be the radio memory.
I would pull the fuse for the interior lights so openng the door won't affect the meter reading.
Make a list of everything you do.
1st 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)
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 hundeds of times so it works.
It takes all the guess work out of the process. E mail me directly at losone@cableone. Net and I will post the final findings on the site.
