Overcharging 17v

Nit quite Lee. Simple diode bridge yes. That's the rectifier part. But in the regulator part, voltage isn't controlled by resistors.
But when the system voltage exceeds a set level, the DC output from the regulator is redirected (or shunted) to earth.

Sorry to correct you, but usually not DC output is grounded, but AC coils of the altenator are grounded by the the regulator SCRs to control max. voltage. ;)
 
That experimental Regulator John Wilson had on my bike years ago was an attempt to increase the battery charging for the std 120 watt alternator I had,his devise failed as it produced damaging spikes. John then went Kawasaki 250 watt alternator conversion. Very clever bloke.

Yeah I know. I was trying to write a dumbed down version for non-engineering types. I figured it was simpler to describe it as a simple two-way switch the way I did. Going on about AC grounding might have been a step too far.

I've seen wiring diagrams for RRs that appear to have two stage AC grounding. Half wave and full wave. I dunno whether they're controlled that way by the little brain in the box, but I suppose it's possible.
