Great stuff, as usual Mike. Who would have thought watching an alternator rebuild would be so captivating! I just love the your watch maker attitude, employing precision and respect for every part.

[@MikesRestorations]

Thanks Christopher I glad you enjoyed the video I think everything is important

[@Workshop43]

Another cool video! Watching your videos is like meditation❤

[@MikesRestorations]

Thank you workshop!

If you have the space and the money, you should look into getting a vapor blasting cabinet. This process produces parts that are arguably as nice as new.

Thanks Mike. So many people around the world benefit from your amazing videos and dedication to perfection, I bet your dad's super proud of you. I'm sure there's car crazy kids that haven't even been born yet, that will be learning from your videos in time to come. Please restore a 3.2 carrera cabriolet next 🙏 😉

7:10 I had no idea you can pull the dust shields off this bearing to inspect the balls/race. Thank you for the great video, well done.

[@MikesRestorations]

Amazing looking job again. I like how you give a lot of credit for the help you get. It shows how humble you are even in front of this masterpiece of a job you are doing on this restoration !

[@MikesRestorations]

Thank you..There is a lot of outside influence that is aways greatly appreciated=) Cheers!

[@MrBecker666]

I swapped my alternator on my 993C4S but kept the original which was working fine until my belt broke so probably the diodes went bad I'll try to rebuild it myself&keep it handy

[@marionfisk7926]

Great video Mike really provided some good information first time I’ve ever seen the inside of an alternator and how and why it works.

[@MikesRestorations]

Hello Marion Im glad you are able to finally see an opened up alternator. It's really not to bad a project. Not many people try it..the popular choice is to trade it in on a reman.. Cheers!

[@911highvoltage3]

Simply amazing. Fantastic job.

[@MikesRestorations]

Thank you very much!

[@restoblastrestoblast154]

Nice job Mike, the starter motor i can't wait to see.

[@MikesRestorations]

Thanks Restoblast Starter will be replaced with a NOS version..unfortunately the one that came on my car was incorrect

[@Anti-Static_Matt]

Another awesome video Mike. What a transformation, amazing.

[@MikesRestorations]

Thanks Matthew The aluminum really came out nice=)

[@gaijinsumo]

Great video, as usual Mike!

[@MikesRestorations]

Thanks John! Im glad it actually works=)

[@remcotissink]

This was really straight forward. Almost too easy... Funny that a diode was failing, they are usually bulletproof.

[@MikesRestorations]

Hello Remko Thanks yeas not to bad to rebuild.. Diodes don't really like heat..not sure what makes them malfunction. Heat or overload at some point

[@peem1244]

Hi Mike, hope all is well with you. Super job on the alternator, just a pity to get dust on it once it's fitted to the engine! I'm a big fan of the Dremel, or any other multi-tool. Where would we be without them these days. Thanks for sharing. Stay safe and keep up the good work. :)

[@MikesRestorations]

Hello Pedro Thank you=) All is well here and just getting thru the heat of the summer Im with you! definitely a big fan of the Dremel. Cheers!

[@danwood1047]

Your description of the function of a diode was spot on. I've heard them referred to as rectifiers but I think you used the term diode exclusively. Is there a difference between a diode and a rectifier in an automotive alternator? Thanks for another great video, Mike.

[@MikesRestorations]

Hello Dan The diodes act together as a unit that is called the rectifier. There is usually 6 large diodes in most alternators. 3 positive and 3 negative. The stator is wound with 3 windings. with 3 leads that wire into the diode pack. 3 phase. The rectifier assembly or rectifier /diode pac converts the alternating current generated buy the stator and is sent through the diode pack or rectifier where the current is the converted to DC and off to the main terminal that hooks back up to the battery. Alternating current is squeezed thru the diodes and cant come back so it then becomes DC. One way to think of it is the alternating current is rectified into DC current. Hence rectifier.
