The relay is a simple black cube with five prongs. I am unable to see anything on the inside. On each of the relays that has burned out, the plastic housing at the base of the prong, is melted and slightly bulging. I can't see the position of the relay. However, I did put a voltmeter on it and checked for continuity across the prongs. I found that the continuity was the same on a good relay as it is for a bad one. Makes me think the bad relay is "frozen" or "burned" into it's normal position and unable to switch to the position it is supposed to be in when an electrical charge is applied. In other words, I have no idea what I'm talking about.

Does my description tell you anything?
