Thanks Bill, for the congrats.
Sure sounds like a loose or bad coonection to the fans. Make sure the contacts in the connectors are clean. Sometimes the wire crimps on the connectors themselves are bad or loose. You may not be able to see them, as they are tucked inside the white connector. You may also want to check the ground wire for the fans. Mine is located in the wiring loom that feeds the fans and is attached to the frame near the lower radiator hose connection. Mine was being pinched between the hose and frame.
I noticed too, that it did not lower the temperature when they kicked in, maybe they just maintain steady airflow so it doesn't get any higher. I don't know what rating the temperature switch is set to activate at. And I have not run it long enough to see the needle readings and take note of them. I guess I need another "Test Drive"!
