For you electrical guru's.....(ie: Bob, John.....)
I have an LED attached to the orange wire on my Jusnes Modified electric fan controller so i know when my efan comes on......now when i am driving, the air that is blowing across the fan causes it to turn......and while it is free spining, it puts a slight electric charge onto the orange wire causeing my LED to ever so lightly light up......
my question is, how would i go about making it only light up when the controller puts power to the fan?

it is hooked up to the orange wire from the controller to the fan motor.......it doesn't have power from the controller on it until it reaches the temp setting......when the fan is turning from the wind blowing across it, it is creating a small amount of electricity to travel back through the wire from the fan motor.....

I don't have a controller on mine so I don't know how yours is wired. Mine just uses a fixed temperature thermoswitch and a relay to switch the high current wiring going to the fan.
If I had this problem on mine, I would just change the source of the LED's power. Instead of powering the LED from the switched fan circuit, I would power it from the 2 wires that power the relay coil (pins 86 and 85). That would isolate the LED from the fan circuit.
Assuming that your installation also uses a standalone Bosch pattern relay, you should be able to power the LED from the wires using those same pin numbers. If the controller doesn't use an external relay, you could add one.

Well, that will work but some real value comes from knowing that the fan circuit itself is actually drawing power.
Personally, I'd be fine with it working like you have it now. The slight glow from the motor generating power as it turns confirms that the fans power and ground are actually still connected to the orange wire and the vehicle ground.
To me, that faint glow is a recurring diagnostic that the system is properly wired. I'd leave it alone.

The fan is generating power. Due to the residual magnetism in the fan motor and the windmilling blade. You get a very small voltage.
If you were to pull the relay you would get the same effect, as long as the led is still wired the same.
