Well how stupid can you be? I was using my 2013 Range Rover sport to jump another can and did the unthinkable and swapped the cables. I did not realize this at first and the Land Rover was running when connected, after 20 second the Land Rover shut off. I then saw the cables were reversed and the jumper cable was very worm; crap! Now I have two cars that will not start. I looked at fuses in fuse box next to the battery as well as behind the glove box and nothing visually is blown. Car still has power but will not start.

I am hopping some sort of fuse or relay protected the mother board!!
I do see what appears to a breaker between the batter post and the cables on the positive and negative each side of the battery, maybe this is something to check?
Any help would be appreciated as I do not want to take tis to the shop?

One last note of detail: went to remove the positive cable to check the possible breaker but the ignition was evidently still on, I heard a light ark went back to shut it off but now dash will not light up.
Thanks in advance!

 

Well, I used a battery from my BMW and it actually started, yea!!

So, if this unfortunate happens to anyone else here is what happen after I reversed the cables:

Range Rover was running and even after connecting the cables incorrectly nothing happened but after 20 seconds after connecting to other cars' bad battery the Range Rover shut off and cables were worm on Rang Rover side.

Car would not turn over and after 10 -15 minutes instrument panel would not light up. Even when I tried to use jumper cables to another car it still would not tune over. It actually did for two revolutions and then battery got weaker, and I heard the electric chunk, chunk sound; again not the solenoid. The battery was so damaged that jumping it would not work. I did not get sparks when connecting the cable incorrectly because the other car’s battery was so dead, the interior light would not come on.

Hope this helps someone in the future.

 

Thanks for giving us the solution. I saw your post but I know nothing about 2013 RR’s (other than having driven one once).
