Parasitic Draw! Part 1 - Diagnosis (Acura TSX)

Once in a while this sporty Acura TSX will drain its battery overnight. So we're dealing with an INTERMITTENT PARASITIC DRAW, one of the most time-consuming diagnostic problems that you may come across!

Let's start from scratch and perform a couple experiments to determine the state of health of this Acura's electrical system and look for clues that might lead us in the right direction.

Enjoy!
