To debate that anything never caused an issue in any vehicle is the true folly.

Everything needs occasional servicing. The factory didn't care about 50+ year life spans so you are on your own to keep up with this kind of stuff.

Pretty obvious your level of comfort with electricity is very low.

not on mine... while the alternator on car is the correct output, something that factory never did, the ammeter won't get ( or barelly get ) any load reading . that was the real problem for them... but... I have discussed and proved this many times allong with @mattax, @71deputy and some other

just those what doesn't understand how the system work, will deny everything

dayclona, would that last pic you show for $44 from advance possibly be small enough to be fitted into my 69 charger ralley dash and look close enough in font to the rest of the dash gauges ?
