NOTE: I've seen several people get flamed on other forums for using an electric fan. This is a TURBOCHARGED application, mechanical fan is not an option.
So I have the Flex-A-Lite 40 electric fan from Summit. I'm not wiring for A/C or a manual switch, but I am running for a constant run application where it stays on until it cools the engine compartment to the desired temperature (redneck turbo timer
So three wires, easy enough right? Wrong. Where this gets interesting is the battery has been relocated to the toolbox in the bed, so I stuck both of the hot wires on the terminal where the positive cable from the battery goes into the fuse box and the ground cable is hooked to the ground strap coming off of the engine block. The temperature solenoid thingy was mounted in the radiator as close to the upper hose as possible, per instructions. The motor was definitely warm (I decided to set my boost pressure solenoid, so I know hitting 12psi a couple times warmed that motor up pretty good). No fan. Turned the temperature dial all the way down. No fan.
What did I do wrong?
