I guess there was a loose connection somewhere that I snugged up just enough. My guess is one of the wires going into the relay was loose.
Many times the connector wires that shove into the back of the plastic relay base work loose. They need to be pushed back in till the spring clips on each wire solidly snap in place. If it will snap into place. A frequent spot for corrosion.
