Assert.Equals of two objects implementing IEquatable (T) does not use the equals method

Question

I have a custom Type Type that implements IEquatable (Type). Then I update two instances of the type, none of them are Null

Assert.IsTrue(obj1.equals(obj2)) //Success
Assert.AreEqual(obj1, obj2) //False
Assert.AreEqual(Type)(obj1, obj2) //False

The first gets to my equal numbers, the second to ToString () Any suggestions?

Update
some code to illustrate: http://pastebin.com/1uecrfeW

If I need to override the base values, even if the best (general) values ​​are available, then what use is the implementation of IEquals (T)?
