I was having a problem with the battery going dead over night, I checked the battery and alternator both good. I then pulled the ground off and put a test light between and found a draw, started pulling fuses and found the interior light cicuit was the cause. when the car is off and no doors are open no lights are on? all the lights seem to be going on and off properly except there is no delay when you close the door. Does anyone know what would be causing the drain when no lights are visibly on?
