I have the fan controller, 425 flex-a-lite fans, and two 30amp spst relays. I cannot get the hks controller to turn the fans on. I have downloaded numerous diagrams and tried anything i thought would work. I checked and re-checked all connections and fuses. The controller gives a display that the fan is on, but the fan w/n come on. The fan is new, only had it four days. I have had th controller for two months only used it for temperture readings. Please help if you can, and thanks for any advice..
