OK, I need some more advice. I unhooked all of the wires (except battery) from the relay to test the relay without any potential load. I used my test light to see if the relay was passing current to the kick down/governor post. As soon as I touch the kd post, I pop the fuse. I assume that means the relay is shot. Correct assumption?
Part 2, where should I look for a relay. Is this something my NAPA store may have, or do I need to look at specialty restoration parts stores?
