I followed the install instructions from 1 of the threads here on how to wire up my intercooler fan using a switch and a 30 amp relay. I finished the install and did a triple check on my wiring, but the fan won't come on. I guess it's possible I have a bum relay. (Fan works when I connect it straight to the battery) My question is - why is the relay necessary? Wouldn't it be OK just to run power to the fan then to a 10amp fuse - to the switch and then ground?
