Thanks for the information…

I’ve a few heavy duty belts in my time in the navy and elsewhere, on occasion.
I just got a nasty high frequency type sting out of an unplugged shaver whilst looking for obvious faults with the charging circuit. The battery hasn’t a lot of life left, either
It actually felt like a needle going in & rather unpleasant. So non fatal power can be waiting for anyone.
Unlikely to kill directly -due to low power of course , but secondary harm is possible by sharp moves away or for people with pacemakers etc.
There is a small transformer on board which implies some kind of oscillator to change power circuit function.
This is the likely source of remanent high a.c voltage.
I don’t have a circuit diagram to expand any further, but a multipin IC chip is right next to the motor and could be quite complex in functioning.

Hi Roger,

Yep, fair enough… 🙂

I think this comment is a combination of a bit of tongue-in-cheek by the author + “covering ourselves” in case someone does manage to give themselves a shock!

Kind Regards,
Pierce

Thanks TR,
Good luck with the replacement process…
Cheers Pierce
