coolant fans are not running, i have wired the fans direct to the battery and they are running fine, ive checked the voltage to the temperature sensor and have removed the temperature sensor plug and bridged the wiring of the sensor to act as if the radiator requires cooling, from there the relay does not click on nor does the fans operate. the fuse board all seems fine nothing melted. I am thinking of by-passing all of this and wiring a 30amp relay from the battery with a timing circuit. does anyone know how long the timer delay is after the temp probe has switched off.
