Hi WannabSmoker;
Welcome to the forum.
For myself your question is very difficult to answer. Smell and taste is very subjective. What smells burnt to you, may smell favorable to someone else. Also you need to describe the smell you are detecting. Does it smell like burnt wood? Burnt food? Burnt electrical wiring? Or something else.
You need to describe how much smoke you applied to your ham. Did you purchased an already cured ham, or did you cure your own? If it was already cured, was it a smoked cured ham? Too much smoke can give you that "burnt" taste.
Also you don't want to clean the Bradley so much that you remove the seasoning on the walls of the smoker. When you clean the Bradley, what chemicals did you use, and did you make sure you cleaned out the area of the heating element?
Finally you shouldn't have thrown the ham out. If you had tightly wrapped it in plastic, and stored it in the refrigerator for a few days, the flavor of the smoke may have improved. Also smoke will only penetrate about 1/8" - 1/4". You could have shaved off the exterior layer of the meat.
