I have just wired mine up. B post connects to the battery +ve, S to a permanent live and IG to a switched live. L to your dash light if you have
one.
Seems to be working for me and not overcharging.

so as mine is on a track car,
where the battery will be disconnected via a FIA master switch when the engine is not running...
I can just link B IG and S with one cable that goes back to the battery,
Is that right?

Might be worth reading up on that. My (limited) understanding is that S is the battery sense to allow the alternator to regulate charging and as mine
is a permanent live then yes I suppose it could link in with the B post but I have a heavier duty wire from the post as I thought this wire has to be
able to handle the max output from the alternator.
There must be a reason why there is an ignition live rather than just being powered by a permanent live all the time? Found this on a random
alternator page
"This terminal is fed by the switched 12V source (from the ignition switch and through the ignition warning light indicator or "idiot
light" . It is used to energize or excite the field windings inside the alternator. The alternator cannot start charging until there is voltage
on the field windings and a magnetic force is created"
I stand and expect to be corrected!
