My Dad and Brother came over yesterday. We were working on my brothers 1984 D150. They were asking about the different voltage regulators and why newer Alternators have dual fields. This information was helpful.
This is almost forgotten technology in recent days, Glad to find something explaining it all, appreciated ! - Thanks for posting it and regards from Alaska!
to the "kids" out there, this was when the soundtrack was played on a record player and the "film" is a slide projector .. the "beep" you hear tells the projectionist to advance to the next slide
Probably was a 'film strip' of 35mm B&W film where you turn a knob to see next image on a special projector. Better than a stack of slides you could get out of order. I remember those in grammar school.
They don't make the tech videos like this anymore. It was so simple to understand ;) Had to refresh my memory on these units, that field test for the generator current was what I wanted to make sure I did right.
That's some awesome Stuff! So much interesting history has already been lost via time and lack of motivation to preserve the non essential stuff sadly now that we're in the digital age. I Love the old voltage flicker points or "over current cut-outs" as they were originally known as, and still to this day use them of all thing's a single cylinder Onan Diesel generator setup. It actually uses flicker points on the 3 dead strokes of the 4 stroke cycle closing points to release excess power stored in a capacitor into the field windings. This brings the voltage of the field windings up a little bit higher as the engine is technically losing speed inbetween the power strokes. Because it only runs at 1800 rpms you'll notice the dimming of a Light under a full load. So their technical name is a Anti-Flicker points when used in this configuration making up for parasitic losses inbetween power strokes. But I also use a Ezgo golf cart with a starter generator system which still utilizes the old flicker points for the voltage regulator. Its amazing how simple things are when you understand how digital copies work, but it's not always easy to figure out how things came to be? The old horse and cart Deal! Which one comes first? Welp we've had generator systems long before we had these fancy silicon chips, so it's figuring out how and to the extent engineers went to make all this stuff mechanical and last for a long time, sometimes out lasting any digital BS. There's just something's which should be mechanical and others which should be all electrical. Truly with proper setup and maintenance of a old fashioned voltage regulator, you will have many years of usage without even knowing that it's all mechanical and electromagnetism that's running your charging systems. Thanks for posting this video it is very entertaining and you may actually learn something as well?!
One of the challenges auto makers have is that gas engines have a speed range of nearly 10 to 1 (700 to 7000 rpm), though accessories like generators, water pumps, power steering pumps and A/C compressors all have to operate at any speed. That means most of these accessories are sized for low speed/low power, which means they're oversized at normal driving speeds.
Yeah~ I did not understand the 'polarizing' and could have hurt my 57 Plymouth I thought. I may have dodged a bullet. This is good stuff to know. Long Live old cars!
i watched a film today called, My Man Godfrey, from 1936, and the head of the house is played by Eugene Pallette who sounds very much like Tech. ua-cam.com/video/Cj8KqZftqcY/v-deo.html

Fantastic video. Can't wait to apply what I learned to my old 1948 Ford's charging system.
Same here but to my 1951 Ford

My fifty one Chevrolet six volt system is still working over seventy years on the same voltage regulator and generator.
its no wonder my 1952 Chevy truck shop manual has more pages on this topic that a complete engine overhaul. Sheeeshh!
Brings back many memories of faulty generators and solenoids!
Great video much needed
good stuff. "Generators nowdays...." awesome

Still used on 70's Cessna aircraft.
great

It's still applied to my 67 Shovelhead😂
6 volt system with positive ground
I don’t always work in hot garages and talk to alcoholic cartoons but when I do I always wear a white smoking jacket
Good yuks. Thanx
Sounds like Mel Blanc.

I love these training vids, but I think Tech is bipolar.
..... I've heard that in about 7 of these other videos! 😜
grate how need a flying car thank you
no need to grate the guys they're just trying to help
now how do we need a flying car thank you
@@pacbeltrr38 yeah I didn't understand a word of that either! Was it English?
i have 1949 chrysler winsor flathead six master tec is the best..if you have an old ca r r dont waste time on other vids
WW ll voltage regulator
trying to hear it over the clicks and pops.
Recorded on a record
@@MrJeep75 an OLD one
Adds to the nostalgia!
I wonder if Tech is played by Eugene Pallette? en.wikipedia.org/wiki/Eugene_Pallette
