I have a cooling fan on a motorcycle that I want to run in one direction when the motorcycle is stopped and the other direction when the motorcycle is moving, with a 5 second pause between changes to give the fan motor a chance to spool down before reversing directions. The speedo on my motorcycle is electric, a freq meter. The pulses are 5 Volt that I'm getting from the sprocket sensor. The fan is 12vdc 10 amps. I'm guessing the signal input should be a pretty high impedance to protect the sensor. Thanks for the help.
