Thanks all for your help. Especially, those that suspected a connection to the water heater
John has nailed it with his information about the electrical aspects of the dual powered water heater. Thanks John for getting my head on straight. I will do future testing once the weather permits, but I am about 90% sure that is what this switch controls. Thanks again everyone.
