Truck won't start after battery was jumped incorrectly.

To make a long story short, I left my lights on and had someone from the schools campus security jump my car. He placed the cables on the opposite poles and the truck was totally dead. I took the battery to have it recharged at Advance and reinstalled. I also replaced the 80A fuse. After replacing the fuse, there was finally power, but the engine is not turning over. What other possible fuses can be checked.

TIA

 

Master fuse?

Starter relay is most likely culprit after the 80A breaker, but really it could have blown anything in the fuse box I would check them all.

 

Thanks everyone! I'll start with the starter relay and keep you posted!
