Yeah, your totally crazy. The hall effect switch is used to sense the position of the rotor so the electronic control circuit knows when to turn the windings on/off at the right time to keep the motor running at the right speed, and to sense the speed of the rotor. It supplies one of the functions of the commutator of a DC brush motor. The other function of the commutator, turning the windings on and off is supplied by the electronic conrtol IC. Attempting to bypass the hall effect switch and supply the windings directly will not work unless you want to manually turn the voltage to the windings on and off at the right time. Of course this would drastically reduce the speed at which the rotor turns. There may be a pin on the electronic control IC to reverse the direction. That would depend on the make and manufacturer of the IC.
