How to wire Electric fans
Hello there I just installed a dual fan set up on my mud drag pickup a 14 inch and 13 inch in one shroud. I have mounted it on my 4 core radiator and have it so it pulls. The fans are out of mercury v8 so I was told. Anyways I didn't use a relay or even a fuse when I wired it the first time. In a hurry. But I had the hot wire hooked to a toggle switch then into a constant power terminal in the fuse box with a conector. It worked for most of the race except in the end. I ended up melting the wire and conector by the fuse box. And the fans quit. The fans are hooked to each other and 3 wires come out of the harness on one side with a black, red, and a orange wire with a blue stipe. The only way we got the fans to go the right way was with the black and the orange-blue wire. Now I need some advice. On the correct way to wire this setup. I plan on wiring the fans seperate with a the hot wires going directly to the battery then maybe run the ground to the toggle switch. Will this work. Other wise I'm going to get a relay and some in-line fuses or breakers which I don't know how big of ones I need and hook them up. Any advice appreciated. Remember I want to turn the fans on manually so I can let it warm up a little bit before I run it wide open for 200 feet. New big block chevy in the pickup that I trying not to wreck. Goes like a raped ape. Thanks guys.
