Morning fellas (and ladies). I recently purchased an Acura TL 2007 model. It is not the type-s but o well, i love it anyways. I have heard great things about these cars and i am normally pretty handy and finding and fixing problems until now!
I come out to a dead battery one morning and think ok alternator is bad or something because the battery is new. I replace the battery anyway and start checking. Nothing is left on, tests show charging system is fine so my next thing is parasitic draw.
I get a multimeter ready, unhook the negative terminal and wait an hour to make sure the car is in "sleep mode". I touch the + lead from multimeter (mm) to the negative disconnected battery lead, and the negative mm lead to the negative battery terminal. I read 0 milliamps, i change it to voltage scale and it's reading 12.48v being drawn. I moved the leads to the appropriate side of the mm to read milliamps, i've pulled every singe fuse (not relays) and nothing changes that reading. I did open the door and read it again thinking it should change a bit with the dome light on but it did not...still 12.48v.
The car is bone stock, no aftermarket anything, so where do i go from here? What on earth could draw 12+ volts while sitting? Have i overlooked something obvious in my testing method?
