Well, in the spirit of the name of this thread....
I know the Hall Effect sensor is really just a magnetic switch, but how exactly does it work?
Three wires:
Red = + 4.8 volts?
Black = ground?
White = what? Continuity to the red wire when activated??
(To clarify, I am asking about the CH Ignitions, RC EXL, and Ralph Cunningham systems.)

You can't count on the wire colors matching the logical value. The typical ignition hall sensors are shorted to ground when a south magnetic field is facing the marked side of the sensor. Of course other systems use different arrangements.
