I have a 2007 6 cylinder that needs jumped almost every day. I pulled all the fuses and tested each one with a test light between the negative thermal and ground cable. I was planning on finding 1 thing causing the draw when I found 9 different fuses setting off the test light. Not sure where to go from here and really don't have the money to take it to a mechanic. Any help would be appreciated. Thinking it may be ignition switch going bad?

 

A test light will not tell you how much current is being drawn by a circuit. You need a Digital Multimeter (DMM) that is capable of handling 10 amps of current. You put the DMM in line just like you did with the test light, negative test lead to the battery negative terminal and the positive test lead to the negative battery cable. Make sure the doors are closed and wait about 20 minutes for the various modules to go into sleep mode, then start pulling fuses. Ideally, you want no more than 50 milliamps being drawn from the battery with everything off.

Also, have you had the battery load tested to make sure it is not faulty? Have you had the alternator tested to make sure it is charging the battery? Most parts stores will test both for free.

Here is a link to a youtube video on how to perform a parasitic draw test:

And, here is a thread from another TrailBlazer forum:

Good Luck!
