Atwood Water Heater Relay - Stuck Closed Again

To answer some of the questions,

I am using he Zettler AZ2280-1A-12D as sold by Atwwod.

Due to the tight space I have to crawl into, I don't think that I will be able to make too many measurements on the element. I will give that a shot though and see what I can do.

Thanks and keep the questions coming. I would like to get to the root of this.
