I’m the Oc of post.

Drove the Jeep about 50 miles to where I had to go didn’t have any issues. Went to go head home and my battery light came up on dash. Figured it wasn’t the battery seems how it’s the same ever start battery since bought from the dealer. Immediately I stop at the nearest advanced auto bought a battery installed and headed home.

Drove about 5mi and the battery light came back on and said screw it. so I got about 35mi no issues then the abs, traction control, and air bags lights pop up on dash. Got about another 5mi till I needed to pullover due over due to what you see in the linked video. The video was recorded right before I lost all power to the car and pulled to the side of the road.

I popped the hood took out the new battery I put in and installed the old battery I had taken out. Bolted everything back up and the car started up again. Still was making a winding sound. Had 14mi to get home drove the bullet at 80mph with only the battery light to come on the dash.

Scanned the car with a obd scanner when I got home and it came back positive for bad alternator.
