I would like to say thanks for all the reply's. I did track the wires, they went behind the converter and out to the water heater. Apparently it was installed as a new way to start the water heater. I would get some spark when it was turned on, but no gas As with all things not being used for a long time, and carful consideration, I gave the gas unit a couple small taps with a hammer. I know, gas and hammer! But it started working and it cycles through just fine.
