starting around
0:02
1950 police and taxi operators could buy
0:05
alternators in their Mopars in their
0:07
plymouths and Dodges but other people
0:10
couldn't later on they started adding
0:12
them to Power Wagons but still an option
0:15
why because they were expensive because
0:17
they were big uh because they used more
0:20
energy from the engine uh than the old
0:23
standby generators but the good thing
0:25
about an alternator is that they can be
0:27
higher capacity and they last longer
0:30
because all the currents not going
0:32
through the brushes and they can charge
0:35
even when idle so what Glenn farrison
0:37
did is for the 1960 Chrysler alternators
0:42
is he figured out a way to use diodes as
0:44
an efficient rectifier to go from the
0:46
alternator's alternating current to the
0:49
direct current that the car can actually
0:51
use so they started out with just 30
0:54
amps which isn't a whole lot and then
0:56
they increase the amperage Year bye uh
0:59
quite rapidly for a while if you wanted
1:02
an alternator that was 60 amps or above
1:04
then they still bought at least Neville
1:06
alternators as they had before they made
1:08
their own but the 1960 Valiant was the
1:11
first car in the world to have a
1:13
standard alternator every single one had
1:16
them uh from 1962 on they switched to a
1:20
new redesign but they still had one
1:22
brush connected to a terminal and the
1:24
other to the housing because it was
1:26
easier to work with the
1:27
electromechanical voltage regulator that
1:29
way
1:31
other than one big alternator in 1969
1:33
which was a special unit with a weird
1:36
three terminal voltage regulator they
1:38
went to the electronic voltage regulator
1:41
in
1:41
1970 and had a new roundback alternator
1:45
with just two terminals one attached to
1:47
each brush it was more efficient that
1:49
way and they could get more power out of
1:51
it in 1972 they had the new more
1:54
reliable Square back which was designed
1:57
for easier assembly and service so the
1:59
earlier ones had to press and solder six
2:02
dodes in the new Square back they had
2:05
two diode packs which didn't need to be
2:08
soldered or
2:09
pressed so if you want to retrofit an
2:12
older car you need to use the flat pack
2:15
electronic 1970 and up voltage regulator
2:19
which is really cheap by 1975 Chrysler
2:22
had a full 100 amp alternator which was
2:24
actually good for 117 amps at maximum
2:27
output the Pinnacle was 1986 7 when they
2:31
had a new alternator at 120 amps Peak
2:33
output uh 50 amps at idle and they were
2:37
actually smaller than the 100 amp but
2:40
bigger than the original squareback they
2:41
were a completely new design but they
2:44
ended in 1989 and after that Chrysler
2:47
bought all their alternators it was the
2:49
end of a long and happy story for more
2:53
including some more details on how they
2:55
