Need some help wiring up my relay! Recently installed a 3 core aluminum radiator and dual electric fan I got from ebay. Wired it up and it worked with no problem, or so I thought. Burned out the fuse and switch. I read I should use a relay so that's what I'm going for. I can plug everything in to the relay and get power to both fans, but it's completely off the battery and pulling power whenever the battery line is plugged in to the relay. It's as if the toggle switch isn't there. All the fan wiring is completely separate from any other wiring on the car. What I'm trying to do is run the fan completely on a toggle switch, not hooked up to anything other than that and the relay. This is the relay, (40amp) and this is how my wires are run. Grounds terminating at the inner fender. any help is appreciated! Looking at getting my z on the road!
