Use Basic Tools To Quickly And Easily Diagnose Simple Automotive Electrical Circuits

Automotive electrical circuit diagnosis isn't always simple but, approaching each issue with an efficient test method helps you reach the solution more efficiently. In this video, we share the process I use when diagnosing a simple electrical circuit. In this case, it happens to be testing for an inop blower motor. Enjoy!

Nobody is breaking it down like you do... If you get an understanding of automotive electrical everything else will come... I really struggle with electrical...You got a Sub...

👍 the industry needs more techs like you!

Loved the use of the diagram and walk through of what you were going to test and where you were putting the leads and showing us in the real world. That is how you teach. Outstanding. Your presentation and execution is perfect.

On a flat rate question. I was a gm tech so in that world many techs after find this same problem one time would probably go straight to that connector and wiggle it as a first step.

Keep doing what your doing!

It's a scope...Scope on a rope! I recently helped a guy on the Honda Odyssey forums who had done all the same stuff....I guided him with some testing to a bad HVAC control head on a 2007 Odyssey. Had never seen it before on the Odyssey but the testing, if you know what you're doing, doesn't lie. He ordered a control head from eBay and a few days later posted that it was fixed! He was quite happy...although he also had a new transistor and blower motor from before I started helping him. Good stuff here!

I hope you share more videos about wiring diagram.thank you

Always good when I see a more simple method to solve a electrical issues. I always hear it from all you good guys, Powers and Grounds.
Always nice to see you Mike, thanks for sharing. Hope all is well down there.

Excellent break down of your steps. You do a great job at a teaching valid points. "No parts required". Ivan would be proud.

Another great job of a perfect diagnosis; keep up the good work. Happy motoring.

OK I'm in love now...please make more more more more more!

"A relatively easy circuit..." but is it Mike? It's easy to guy's who understand it, but not so easy for those still trying to understand it...😉

You are on point Mike...looking forward to more good videos!

Great diagnostic process Mike. Thank you for sharing!

WHY CAN'T WE HAVE MORE VIDEOS LIKE THIS, , BEST TESTING I HAVE SEEN IN A WHILE THANK YOU MIKE

[ismarmeskovic]

Great lesson and in depth explanation Mike!Cheers!

I've seen you on YouTube but never really bothered to just watch but after watching two videos consecutively I immediately subscribed. Love how you not only think but also convey that process

Follow the voltage/current path. Along the way in this case, check the "G1xx" ground by substituting a "known good ground." Circuit now works, back track to locate problem. Sounds simple, and in this case, like you said, it is a fairly simple circuit. It's called "signal (or power) tracing."
It worked for me in the past. Intermittents are a different animal, but basics still are the rule to follow.
Good one Mike!

[blairwilson]

fantastic video, very well explained every step of the way! Thank you!

[mikem]

The best video on simple electric diag
