The more I look and think about the wiring diagrams, and the more I think about what happened, I will double-check the ground. It may not be loose in the plug but it sure might be loose somewhere else. Talking about chasing gremlins! I'll have to wait until after work to check it all out but thanks again. I'll let you know.
