gchunter - any delay for the fan to work is thermostatically controlled elsewhere. If the fan is removed from the system, a simple red to red, black to black should work fine (assuming DC power, DC fan). if you've attached your magnet to the fan - try taking it off until the problem is solved. My magnet was too strong and interferring with the motor. I ended up separating the magnet from the motor by half an inch with spacers.
