Typical causes of battery drain?

Disconnect all wires excepting start and ground. Add accessory wires one at a time and view your resistance on the ground terminal and voltage drop on battery positive remember to do this procedure one wire at a time

FIRST, CHECK THE OBVIOUS. Most cars,have alight UNDER the trunk lid & under the hood. These lights go on when the lids are up. But are suppose to go off when the lid is closed. CHECK THOSE to see if they are on when the lids are closed. ALSO, check the glove box light. NOW DO THIS..... Pop the hood. First make sure NO INTERIOR LIGHTS ARE ON when the doors are open. You may need the door open. ALSO,IF you have a clock , pull the fuse out. Now, Disconnect one battery connection. Put a test light or voltmeter inbetween the battery post and the connector you just removed. IF you have a drain , the light will come on. If the light is on , then anything you unplug now, will be the drain. UNPLUG the ALTERNATOR first. Then remove & replace fuses ONE at a time. REMEMBER, the drain will be on the circuit you disconnect. Whether its a plug or a fuse.
