Tested for parasitic drain in circuit with negative battery cable finding 0.10 Amps. Further diagnosis finding btn#2 at battery junction box removed fuse removed brings amps to 0.00. Also fuse #27 in cabin fuse box when removed also brings amperage draw to 0.00 amps. I'm showing #27 10amp fuse controls : GEM, Audio, Cluster, Interior lamp, Map lamp, Cargo lamp, . My question is, how do I find which item is causing the power drain and how to test each item in circuit? A huge thank you to all mechanics and 2CarPros and owners for your help and assistance you don't get enough praise or thanks for what you do. Thank you all! JJ

Hi,

If the draw stops when you remove the interior fuse, then the problem is after that fuse and not between the two mentioned.

I looked up the fuse number to confirm what fuse 27 powers. Take a look below at pic 1. Pic 2 shows fuse 27, just to confirm.

Here is what I suggest: I would disconnect one component at a time. For example; disconnect the radio and see if that changes things. If it doesn't, disconnect the instrument cluster, lamps, and other components powered by this fuse. If you remove a bulb, it opens the circuit and will help narrow things down for you.

Let me know what you find or if you have other questions.

Take care,

Joe
