There are (if memory serves) 6 diodes in the rectifier circuit, one pair for each of the 3 phases of AC coming from the alternator. Imagine a voltage level going from -20v to +20v. The idea is to get all the peaks going the same way. So, when it's at -20v, one diode is blocking the flow (by resisting the voltage) and the other diode is allowing it. When it flips to +20v, the same thing happens with the diodes flipped. This makes sure that the voltage from that winding through the rectifier goes only one way.
The regulator essentially works like a faucet, allowing the limit of voltage, and clamping down any excess. This is usually dissipated as heat, as the clamping diodes resist the extra voltage.
Electronics 101 lesson concluded.
