I have a 2001 Toyota Highlander which won't start. I also was unable to jump it. When I was looking around under the hood, I noticed that there was a black cable with an exposed end floating near the positive terminal of the battery. The positive terminal isn't completely disconnected, but I can't tell where the cable goes. I have attempted to show in the second photo how the cable with the loose end runs in the same direction of the cable that is connected to the battery.

Does anyone know what this cable is, or how I might discover that information? Any information on how I might repair is also appreciated.

I found this photo which appears to show that wire connected to the positive terminal - enter image description here

I found the photo on this website that is describing how to jump start the vehicle. See the video ‘Locate Positive Terminal’.

You should be able to replace what presumably was a crimped-on eyelet on the end of the cable. As a temporary fix to get you home, you may be able to loosen the nut and push the bare wire between the layers of metal that appear to be there, then tighten the nut up. In both cases it would be worth cleaning the metal faces first to ensure you get a good connection, since this wire will be carrying a large current, so you don’t want a high resistance that will cause a hot spot.
