Hayden 3647 Fan Controller - Help!
I just installed the Hayden controller on my 93 cobra and I can't seem to get it to turn on. I checked and double checked my grounds. In line fuse is fine and relay seems fine. Not quite sure what the hold up is. I tapped into the Red/Lt Grn wire coming off the ignition module (which is hot in run or start) for my ignition signal wire (yellow). Anybody ever installed one of these or have any idea what I might be doing wrong? I'm fairly certain that everything is wired properly. Any help is appreciated.
Here's my schematic (these are wires coming off the relay) -
Red - power - connected to positive of battery
Black - ground - grounded to chassis
Orange - power output to fan - connected to positive of fan
Blue - secondary power output to fan (for mulitple fans) - grounded to negative of battery
Green - A/C Clutch signal (turns fan on when A/C on) - tied off/taped up
Yellow - Ignition signal - tapped into red/lt grn coming into distributor
