I concur. Great to find a bloke who knows what he's talking about and is willing to share it in the patient way you did. You don't have to apologise for complexity and if waffling is adding context and detail than it's allowed too. Great work. Interesting way of starting a fire.

That is the best how to I have seen or read to fully diagnose a charging system fault!!! Thanks!!

Finally! Someone who point out that, you can only check diodes in R/R, not the regulation circuit. It seems that the whole world is missing that.

For flip sakes, been hunting so long for someone with skill at explaining in detail what goes on in my bike. Thanks for your effort and help, much appreciated.

Very good tutorial, thank you. The graphic waveform of AC when idling vs. higher revs frequency and amplitude is so informative.

This is by far the most helpful video I've ever seen on youtube. Thank you James. I knew absolutely nothing about the electrical systems of a bike before this video, and now I feel that I get the whole idea about what's going on in there. You're genius. Hope we could have such educated and knows-what-he-does-exactly type mechanics like you around here too. Such a great misfortune..

I have to add also this is the best guide I have seen from someone who actually knows exactly what they are talking about - well done sir

@robertvandertuin5308

Outstanding instructional detail, thank you for showing how to performs the ohms check on the faulty generator wires, many only perform the rewind.

You sir are an absolute genius. I have a six-month old Harley that has gone through three regulators. After watching your video I'm positive it's the stator/generator that is stuffed. They "The Technicians" keep saying it's a bad batch of regulators, and the only way this could be the case, is if the diodes were stuffed in all three regulators? I don't think so. Which leads me to conclude that it's the stator/generator. Oh and by the way there's nothing wrong with waffling 👍👍👍.

What a fantastic video. I've been riding for years and always wondered about this as had heard about rr's, windings and generators but never knew the setup. Thank you for taking the time to share your expertise.

This is the best ever electrical charging system video ever made. I actually understand exactly how it works now after watching the video Better then evening class. Thank you James Wright-Roberts and please make more videos

Great job, glad that you explained the different symptoms of regulator and alternator failings.

great to see you posting again Jim, along with yourself and Delboy I've learnt so much and saved loads of money, cheers.

@tfm1449

I feel I have a good basic understanding of electrical systems. I have always been reluctant to invest in an oscilloscope, but since watching your video, I see the importance of using one. Thank you James for being patient, and thorough.

Excellent video quality, clear explanations... Even I understood it! James, you are the professor, the master. Please, can I have some more?

Wow. I'm bran new at all things motorcycle electronics, and I'm dealing with the symptoms of flat battery. In researching the possible problems, I found your video. I'm so glad that I watched this one first. Thank you so much for all the time and effort you put into this. You did a really great job, despite your humble self-doubt. I intend to watch this again before I tackle my bike, but I already feel much more confident. Thank you again.
