Ok, so for a matter of years now, I have had a parasitic drain on my battery for my 1997 I30. Several trips to the dealer and my mechanic have only yielded new batteries, alternators, and false promises of it being fixed.
So, being a recently graduated engineer, I am now taking matters into my own hands.
I still need the car to commute, so i installed a kill switch for the time being, to shut off all power when the car is off.
Using a multimeter, i found when off, the car has a 0.12A draw on the battery.
I then began pulling fuses.
When i pull the fusible link for the BCM the draw goes down to about 0.06A. When I pull the fusible link for the power windows, the draw goes down to also about 0.06A. And when i pull both, the draw goes down to 0.01A (normal for the car i think). These are the only results from pulling all fuses.
So, i then began to pull harnesses to try and pinpoint the exact circuit. I found that when i pulled the front left harness on the BCM, the draw went to 0.06A.
And when i each of the harnesses on the power window controllers, it went down 0.015 for a total of 0.06A.
I need help to decide where to go from here. Obviously, I could leave those fuses out, but that takes a lot of features from the car. I want to fix this the right way.
Thanks for the help.
