Totally disagree.
@Red63440 wasn't talking about switching to that conversion style regulator that looks like a points style in the video.
Similarly the alternator he has on the bench is for a 70's style solid state regulator.
I must have had 10 cars with the 70's style solid state regulator never had a problem with any of them.
I converted my Charger at least 25 years ago with a
used solid state regulator it's still in there.
And by the way the old points style regulator is not purely analog like Tony says in the video the points opening and closing is a
discrete signal.
From my experience there is nothing wrong with upgrading to a more modern regulator and alternator.
Just don't go crazy on the alternator sizing and try and always keep a fully charged battery.
People get into trouble putting a high amperage alternator in an old car with old wiring and then running it with a mostly dead battery using the alternator to charge it back up.
In that situation the alternator puts out way too much current for the old wiring and things melt/burn particularly on the bulkhead.
