Well, I put the new relay on by the battery....again. The second time I started the car up the starter stayed engaged until the battery ran dead. I couldn't get it to quit

I know it has to be something simple, but I don't know what. New starter, second new relay, and new switch in the steering column have all been put in. Any more ideas? I am about ready to take it to a shop and let them mess with it
