New Fan Controller 5.27.19 1.jpg

Electromagnetic interference aka "EMI"

This invisible problem has effected audio equipment, ignition systems, fuel injection systems, and even alternators.  The wire from the controller to your fan is emitting this EMI invisible noise.  The best way to deal with this is to shield the wire from the controller to your fan.  See our MORE/PDF on this EMI cure.

​

We received this email from Frank on his alternator EMI problem:

"Its hard to count the number of people who insisted that either the alternator or your controller was defective.  No description of how or why, just EMI can't do that!

If I ever do this again, I'm buying shielded wire to start with!"

    The Auto Cool Guy supplies the Standard Brass Sensor with your controller.   

     

    However, if you purchase a Brass Plug Sensor or one of the Copper Inline Sensors,  we do not supply the Standard Brass Sensor as the default sensor with your order.  

     

    Send us an email on the size of sensor you have ordered!   We are not getting the pay pal notes?

    We get a vast amount of calls and emails from pissed off guys that purchased the brand X controller from that 

    "Racing Company."
