All reg/recs shunt to a certain extent.
As I frequently say, drop the terminology shunt - because they all do that and it just confuses everyone.
Instead, refer to the Podtronics/Boyer Bransden Power Box/Tympanium as a short-type reg/rec.
When the battery reaches it’s target voltage, the stator AC output lines are dead shorted.
Any over voltage is then shunted as normal.
Refer to the Shindengen SH775 and SH847 (also some models made by Cycle Electric, Computer-Fire, Silent-Hektik and even Electrex World) as a series-type or open-type reg/rec.
With these, when the battery reaches it’s target voltage, the AC supply lines are opened up, effectively disconnecting the stator.
Any over voltage is then shunted in the usual way.
@Tornado I don‘t care about the heat, nor do I care about the loss of power at the crank with the additional resistance introduced from a shorted stator.
These are all minuscule quibbles on the scale of things.
What I do care about is the shorter life our stators seem to have these days.
They are fine for 30 years or more, then when we begin installing reg/recs we start to see a huge increase in failure rate.
I don’t believe this is a coincidence.
I also feel it is good for customers of these ‘uprated’ components to be better informed and understand where the compromises are as well as the benefits.
I think it is important to understand the need of a balanced charging system and understand that installing LEDs and a high power alternator is not a good combination.
Funnily enough, this is all stuff that the manufacturers of these components don’t talk about.
I am often accused of hating Podtronics.
I don’t mind them, nor do I mind the $10 Honda reg/rec units bought from eBay.
...if they are used with a standard, unmodified charging system, you have a healthy battery and capacitor, and that you keep your headlights switched on all the time so that the reg/rec has got something to do.
But alas, that is not usually the way it is.
