I am getting no spark on a ryobi hammer/drill

You want a spark on your drill? This drill likely has "brushes" that make contact with the armature that allows current flow so that it turns. If the brushes no longer make contact or the armature wiring is defective then the current flow stops and so does your drill. High quality models provide access to the brushes and allow replacement. But, if the armature is defective or a low quality then consider a replacement.
