I have a slow drain on my car battery. I pulled all the fuse and found that the Jct, pwr/lk, audio, horn, airbag and the alt all pull current when the car is switched off. I am not sure which one or more of these should darw current?
Use a 12volt test light between the positive battery post and the positive cable with the positive cable disconnected from the battery.
Keep key off.
You will see the test light "light" with any drain.
Any drain showing a dim test light is..... OK
Any drain showing a bright light is.....BAD
Disconnect items (fuses) one at a time and watch the light.
Keep the doors closed....the inside dome light is a drain with the door open!
After fuses are checked....disconnect the alt if needed and watch the light.
Keep going until you get rid of the bright light.
