Mach1 Driver 560 Report post Posted August 11, 2021 Rev 3 of How alternators work Edit, I finally replaced my old defunct analog scope with a new, much cheaper, much better digital storage oscilloscope. These things have changed dramatically with the advent of digital circuitry. They can store the waveform, take the measurements and display them, do math on them (like taking the mean) and scads of other really neat features. So I was curious what the wave looked like at our alternator’s neutral stator terminal. Turns out it’s a pretty wicked sawtooth. So now I can dispel any mystery as to how to hook-up a choke heater to the stator. I’ve also added a page on the “Radio Noise Suppression Condenser”. Edit, this site has been down for "Bandwidth Limit Exceeded" many times, so I have added a method to view the schematics and other technical documents: https://drive.google.com/drive/folders/10FqYlsGT1XXr8B5TCF9WAASkU4vdPtuJ?usp=sharing How Alternators work3.docx 2 1 RPM, bigmal and TexasEd reacted to this Quote Share this post Link to post Share on other sites
Midlife 814 Report post Posted August 12, 2021 Fantastic! I have to say that this forum is very lucky to have you around to explain all this cra...I mean stuff...that is incomprehensible to the rest of us. Thank you! 2 RPM and Mach1 Driver reacted to this Quote Share this post Link to post Share on other sites

Vicfreg 771 Report post Posted May 8, 2022 Nice article, well done! One comment on the oscilloscope section. Yours has a "mean" value. On some scopes, the mean is calculated based on the cycles (average value of the number of points displayed) that are displayed on the screen. You have about 2-1/2 cycles shown on the screen. Some scopes have what is called a "cycle mean" which give you the true value for one cycle. Would be interesting to see if your scope has that, and if so, how the mean and cycle mean compare.
