E-fan question

I am running electrical engine cooling fans on my 2000 f150.I installed a light in the dash connected to the fan power switch so that I would know when it is working.The problem is driving down the road the air moving thru the fan blades makes it spin which in turn generates power and turns the light on.I has an electronic controller with a relay that controls it in a 12v system. I was thinking a one way diode could take care of this. But I cant find anyone that can help me out

Although this is a double post, I'll venture to respond. Buzz gave you good advice in the electrical column. I'll counter here. Why do you want electric fans installed on a truck that already has a mechanically driven fan? Most engine cooling fans' purpose is to continue to cool down the engine after it is shut down. With the truck in motion and the engine fan running normally, an auxiliary fan would be redundant. In addition who or how will the fan know to shut down while you are in the store? You'll need a timer for that. I think if you wanted to do this right, there are kits for the installation of the fans that include thermal switches for the purposes you need. Have you checked them out yet?
