I’ve had charging issues in the past with this car I tested my battery it said bad battery, changed the battery, battery light was still on. (Mind you my car still started) Had somebody Change the alternator (it still started before the alternator change) there were some sparks that flew but before he started taking off the alternator he disconnected the positive cable from my fuse box underneath my hood. (Don’t know why he did that) as he was taking off the alternator the last thing he took off was the positive cable at the back of the alternator by the pig tail, there were sparks that flew as he was taking off the positive cable to he alternator as I mentioned before so we finally got the new one put on and now my car will not start it did start but immediately shut off it felt equivalent to running out of gas. My lights on my dash came on and then everything went dark on my dash can someone please explain what is going on with my car the lights will come on when I lock and unlock my car but my car won’t start.

Is the starter working normally? Do other electrical components work properly? Also, you indicated there was a spark behind the alternator. I need you to check something.

Check to see if there is power to the B+ voltage wire. The wire can be light blue, tan, or orange in color. See pic below.

Let me know what you find. Also, keep in mind that the electrical system is regulated through the powertrain control module (PCM). It doesn't have a voltage regulator at the alternator. If the alt checked good and the battery light was on indicating it wasn't charging, chances are the PCM is the issue.

Let me know.
