If I had seen this during my apprenticeship I would not have become a nurse.

Great video, first time I am learning about voltage drop testing...love that!

This is just up my street; very detailed and informative. Justin you're a star.

I am a certified mechanic and was looking for a how to video cause I was tired of typing of typing out the explanation on social media. Sharing this video will save me a lot of time. Thank you.

Very educational for us getting ready for the A1 ASE Test! Thank you so much for making this video!

This is an amazing video. You must be an engineer. I love engineers!

E X C E L L E N T demo, very nice setup too.  Nice job indeed.  Sharing your knowledge is greatly appreciated.

Thank you for this video - I’ve watched about 10-15 different videos on this and this one was the most clear! You’ve helped me diagnose the issue with my project car!

Omg 🤯 it makes sense now. I can't thank you enough....😭

Frick this is seriously the best video!

This was very helpful. I'm trying to figure out the click coming from my 99 Buick century at the solenoid on the starter and this helped me to understand the starter motor a lot better. Excellent!

wish we have this in our school,  students will learn a lot more than written visual aids.

Love the way this is made so simple. 4 places to check for voltage drop in the starter circuit.

Awesome video...saved me from buying a new battery.

Trying to diagnose my 62 Impala.  This video was really helpful!
