Ballast resistor question

I'm working on a 1970 Dart. All the wiring is new M&H stuff. I've had the car running for a month or so and have put a few hundred miles on it and everything runs fine. In working to check various connections to be sure they are secure, I put my finger on the ballast resistor and burned the **** out of my finger. This is a 2 terminal original type that has a metal band around it that carries the bolt that attaches the ballast resistor to the firewall. It is the band that is hot. Is it supposed to be that way??? It seems to work fine.

Yep, normal.
