  1. 2015 ATS 2.5l electrical issues

    Cadillac ATS General Discussion Forum
    Does anyone have any idea what could be messing with my car electrically? I’m just looking for advice here. It keeps killing my batteries and this will be the 3rd battery I’ve used. 2 new and 1 used. I’ve had the starter, alternator and battery tested and it always comes back as a bad battery...
  2. 98 Deville electrical issues! (Haunted?)

    Cadillac DeVille 1985 to 2005 including:1985-1992
    Just picked up a 98 Deville with only 70,000 miles on it!

    Cadillac DTS Forum 2006 through 2011
    Hi friends, I'm swapping out a bad starter, and while I'm waiting for a part to arrive (replacing the pcv vacuum tube that connects to the side of the intake manifold) I started poking around and having a general inspection. I noticed in the back of the engine, passenger side, two electrical...

    The old starter was dragging bad, and upon removal the nose was broken. There were no other electrical issues, and I bench tested the starter before installing.

  8. 2014 ATS Engine Fire - Need connector identified!

    Cadillac ATS General Discussion Forum
    Had a small fire between the turbo and the firewall. The fire charred a few things, but I'm unable to identify a badly burnt connector that I'm sure will need replacing. Any help or photos would help a great deal. Engine also throwing a P0171 engine code which I imagine has to do with the...
