Yes sir, I did know that, but line loss all the way back to the battery I've always had better luck with deeply discharged batteries by going directly to the post (The end all of power and ground in the car). Found this out back when I first got my 2000 528iT and it had a nice draw issue going on with it. The lug I'm talking about that the heat shrink had failed on I believe was the line going from the batter to the front of the car. There's a metal, in-line connection lug on that line about 18" away from the battery terminal.
