I concur

Also, the voltage should not change much at the alternator, but the
amperage definitely will.  If the voltage varied that much at the
alternator, it would also vary everywhere else in the system and fry the
car each time you drive it.  Capacitors help regulate CURRENT, they should
have little effect on VOLTAGE.
