Here is a useful video for testing RR... but you need a decent meter ( I used to have FLUKE meters at work, but forgot to pinch one when I left - they are expensive but well worth it ).

Seems the first one he tests is a normal RR ( SCR shunt ), the second one a Mosfet ( shunt ) and the Polaris one is a 'series' type ( whenever I see the Polaris name it seems to be referring to a reasonably priced upgrade to a series type regulator ) the Polaris does indeed have mosfets in series with the diode pack rather than in parallel with the regulator - so rather than loading up the stator all the time and 'shunting' ( wasting ) the excess current, the series type reduce or increase the amount of power they draw from the stator and give it a much easier life.
