I didn't fail on show the alt stud hooked directly to the batt... simply because is not... they are linked sure, but running throught the bulkhead, amm, starter relay stud.

i simply did show how how are actually wired every car with full load ammeters (shunted systems are a diff story, but not so different)... Mopars, Phords... whichever other brand. And ALL cars with ammeters get their devices sourced on alt side of the ammeter... no matter if an intermediate splice, ammeter stud, alts tud or some juntion point... Fuse box is also sourced from this side, being spliced into the amm-alt line. Yes, it says BATT, but just as a reference for a constant power coming from the power sources... alts if cengine is running or batt if engine is off.... or batt-alt combination depending on alt capacity.

JUST the starter motor is not sourced from alt side, of course. Sometimes some accesories which just work at certain points being not a constant power source suckers, like power windows could be also on batt side not on alt side
