"So hot" is meaningless, how hot is it actually getting?

There are a couple of large resistors mounted under the regulator that can generate heat. Make sure some air can get to the resistors, so the heat does not build up.

Make sure you don't have a short somewhere.

yes they run hot until the voltage is satisfied all ceramic resistors run hot under load

I burnt up a couple regulators till I found there was a bad path (ground) back to the battery. It's a good practice to occasionally clean up wire terminal and body bolt connections to keep things working properly.
