im 86 years old been a mechanic most of my life understand voltage drop very well that being said for someone learning this is the best visiual explainition that i have ever seen i mostly learned trial and error. can remember the first time i had headlamp that woldn't work had power and known good bulb and without load had a good ground spent most of the day figuring out what could be wrong ran new wires and problem fixed this was very old vehicle no computers had even point type ignition. worked good with new wires then removed the positive lead connected original positive lead bulb worked  then removed new ground lead and reconnected old negitave lead bulb wouldn't come on wound up being a connector between dash and under hood had the green curse. wish had known this back then but will never forget load testing is the only way

Man you’re the f**** best. You have helped me pass 7out of 8 of my ASE tests because of your videos. I now come to your videos for nice refreshers thank you so much for your hard work and dedication to the younger green and older veteran techs!!!

Best training videos is an understatement!!!

I learned this in your class with instructor Jose , awesome class the electrical class👍👍👍👍

just found your channel today thanks for sharing

Awesome video BIG O, thanks for sharing the knowledge!!!! Have a great weekend!!!!!!!!!!!

Great video my friend thank you

May I request a video demonstration using specifically an Amp clamp to test for parasitic draws maybe a module that won’t fall asleep and draws above 300 milliamps Great video thank you!

Great

How about testing a solenoid pack with the readings of 12.6v 12.5v and 12.4v to determine a high resistance at either point y or z? Also a short at point y or z? For the A2

An OHM meter does have its place but good conductivity doesn’t mean good conductivity.Voltage drop method proves good or bad conductivity because of current flow.Vd=IR   Dynamic—must be powered up .Nice presentation CHEERS

Think we missed an opportunity to expose the masses to Kirchhoff's Voltage Law and nodes. Maybe even a little math. 😮

Continuity tests at a few ma... a voltage drop test is performed at typical application current which may be 1, 3 or up to several hundred amps. Continuity will not identify gangrene or bad connectors all the time... high current testing will

Great information

Enjoy your weekend with all your family around you,Sir

MR DIAGNOSTECH. Voltage drop testing great tutorial
From Nick Ayivor from London England UK 🇬🇧 ⏰️ 10:22AM Good Morning 🙏 🌄,Sir

The wires are hidden under the table, I cannot see what is happening, too confussed,

I was referred to you by Shotgun Diagnostics channel. He said you sell the JH APT 100 pressure transducer kit that he did a video on. I looked on your MAT website store and I didn't see it listed. Do you still sell that kit? Thank you

How about using a LoadPro? It makes a voltage drop way easier

I am still confused on the concept," If you see source voltage, you are missing one of the two."

You state that you lose 7 volts across the switch, but I think you meant to say 7 mV. This might be confusing to a newbie.
