Everyone this one here is a crazy cool diag. It first came in with no charge, flickering lights problem. But when I went to diagnose it, the vehicle did not respond. Let’s see what we find on today’s video.

This guy knows what he is doing. Follow his procedure . Voltage drop tells a story. Awsome job.

[@TheEvilMechanic]

Nice video, obvious issue for seasoned mechanics. But good lesson for beginers. Keep up the good work.

[@OzMechanics]

Thanks for watching

[@albutterfield5965]

I am impressed with you trouble shooting skills and your common sense approach

[@un-limited7009]

Thanks Keep them coming . You make it look less Intimidating to diagnose.

I love these ground problem ones. Specially after the computer, alternator, terminals and new battery have been replaced.

[@OzMechanics]

Yep, these are the ones that make the tech look like a rock star. Really figuring out the problem. Thanks for watching

[@rumithesquirrel7816]

@@OzMechanicsI need one of these tech because I keep having to replace my battery & alternator 2 each in 1 year. They keep telling me it's the alternator or the battery.

[@woppini]

I had a Corolla do this, and the exact same thing happened. Bolt snapped. I just stacked both grounds on the remaining bolt, cleaned up the chassis contact area and spread some dielectric grease on it. Good video, thanks for posting

[@spelunkerd]

It is always nice to see a guy logically work through this kind of problem, like you did here. Lots of ways to do it, I like your quick, simple method of turning the key on to get electrons flowing. On my truck there is an additional separate ground wire connecting engine to chassis, although I suppose yours may only have that transmission ground.

[@joshuaburt1017]

Good video brother. Alot of technicians misdiagnose things because of voltage drops. This should be one of the most taught things in the automotive industry!

[@chrischrismon2766]

I guess that issue is now stored in the memory bank! Thanks! Awesome video

Thank you. You did an awesome job showing me how the system works. You just earned a new subscriber.

Glad you liked the video. If you want to check out a really fun out. Look for the camaro series I did. That will have your head spinning

[@rayp.454]

I figured it was a connection/ground issue, but thanks for walking us through the process. Well done sir!

Great troubleshooting Oz !!! Thanks

Awesome! I’m definitely going to take knowledge from this video! You always teaching me something new! Thank you!!!

[@roxanneabbott8424]

Loved this video Oz!! Great job!

[@paulmonk7820]

Why not put both of those cables on the same bolt? Looked like it was bolted to 2 different metal pieces, which would cause problems later. Think I would have just connected the long one to the battery instead of running all that current through rust prone connections. Or at lest put something on them to prevent further rust. Second thought...is there a need for the chassis ground there, or are there other ground points? If needed, just run both wires to a new negative battery connector. Good troubleshooting, tho.

Great job Oz!

What did you clean the ground cables with?

[@bryanv.8066]

I recently had an issue on my own car, the voltage was lower inside my car at the cigarette lighter /cell phone charger than at the battery. Upon checking I too found that the negative cable underneath the battery was actually disconnected. So my vehicle was only getting some ground from the much smaller cable going to the body, so what I did was not only fix the bad connection under the battery but I also added more ground connections. I ran a ground wire from the alternator housing to the body, one from the engine to the body and now my voltage inside my car is the same as at my battery, which BTW went up a little higher also when running now. Lesson here Is : check your batteries cable connections and fix/upgrade like I did, your car and you will benefit from this :)

[@Lambros_Stefaneas]

You should put one more ground connection from the cylinder head to the engine block, just in case the head bolts are rusted, and also if the head gasket is not metallic, and doesn't have good ground 🤣🤣🤣🤣. But, it's true what you are saying, the more ground connection, the better is.you eliminate for life, bad ground connections issues,and I think, all the electrical system, will last longer.

My 2009 scion had the exact same ground issue. Same ground...

[@HouseCallAutoRepair]

That's funny... My Corolla just started with an intermittent loss of charge, AND a simultaneous P0741. How many people would start with a new alternator? I HATE intermittents! As soon as I take it out of gear, or slow down, the voltage come right back up. I'm probably going to fix it by accident, while trying to make a video out of it...

[@craigconway4093]

Great :)

[@sh2697]

i wish you had the video of cleaning the cables. That would have been nice

[@OzMechanics]

It was just getting a wire brush and cleaning the rust off.

Wish we had honest, good mechanics my way smh 🤦 I seem to be having this issue with my 98 toyota camry. Changed My alternator 3x N brand new battery but after a while my car gradually loose power n then won't start. Starts right up with a quick jump. Driving me crazy. I'm going to check wires though and fuses..
