Thank you for using different scanners. Not everyone can afford a Snap-On scanner so showing a cheaper scanner to diagnose is a huge help as well. Thank you!
I wanted to let you know that I was prepared to spend over 300.00 for a new alternator for my 2006 Mustang V6. After watching you video, I decided to check the connector. I do not have a scanner but iI understood your diagnostics so i set my iPhone up in the driver's seat pointed at the cluster and did a face time to my iPad. Whenever I would move the connector, the battery light would go out. For about 30.00 I was able to replace the connector and now I have no light or charging problems and you saved me about 270.00. That is worth a like, subscribe, and bell for you, my friend.!
Wish I had seen this video 2 months ago. I had the same issue for about 3 months changed alternator and new battery. Still service charging system messages. I ended up finding it by accident as Everytime I messed with the connection noticed I got the error Everytime. Changed and no issues. This was a great informational video.
Let me tell you something. You are a car doctor. Really you are amazing. The best one who move step by step and analysing the root of the car problem with an evidence . Thank you doctor.
I've got a scanner that'll show the data with the engine running. I'll check out the 2008 chevy cobalt tomorrow to see if it's just the connector. Thanks for posting the video. Son claims that he didn't have any issues prior to jump-starting some guys car. I told him that's why I bought a couple of those small digital jump-starter units, just because some vehicles can get damaged after using them to start other vehicles...
Glad to see you again!! Excelent video..also I own the MaxiSys-elite version in set with the Maxiscope MP408! Both tools work great. I got another Oscilloscope ; the "Hantek DSO3064 Kit VII 4CH 60MHz Automobile Diagnostic Oscilloscope"Tools that all mechanic must have at the time of making a good diagnosis! and for beginners are excellent to! Great video my friend...take care and keep going!!!
Yes you can , but seeing it on the scope lets you know for 100% sure that you know what the problem is . A good tech will confirm the problem before making the repair . No guess work with a scope .
nice video, I am having the same problem. I noticed that the alternator will kick in when I touch the connector. without having the scope I think is a good bet to replace the connector.
P0622 means that it has a alternator connection issue than? My battery light has been on for 2 weeks and I can't figure out the issue. The alternator was testing at 14.05. My alternator is at the bottom so it's hard to check the connector down there.
i had a. similar issue p1637 and p0622 Haness was ok i swap alternators because ei had a new one laying around and i had the old alternator and battery tested and both came back good and i was looking at my data stream for the f terminal and it had a constant pattern but it would suddenly drop to 0% then right back up to 5-89%ish any ideas I tried wiggling my terminal also but no noticable drop in the scanner
The battery light is flickering off and on.... toyota corolla 2010..., its gone through two batteries in one year!! The car starts but if i test the battery its losing charge .... why? The light doesnt stay on just flickers off and on..., second- the headlight occasionally dim not always but they do dim
If the signal was coming from the ECM, why did the signal drop out? if the connection between the plug, and socket is bad, you would still have signal at the plug, where you are probing it.
Okay, you clearly have a connection issue at the alternator. How are you determining that it's the connector and not the alternator. Could be contacts on or in alternator.
Agreed, when I get a situation like that, I will disconnect it and visually look for terminal damage/problems, test the terminal tension/fit, tug on the wire-possibly broken inside insulation. Also sometimes a component responds to pressure on the terminals going into it - then that part has failed. It all depends on what you find as Duane mentioned "Evidence" in a particular car, the connector pigtail is a practical way to repair a problem in that area and may be all that is needed.

Thanks, James, I appreciate your comments. Glad it helped

Excellent tutorial, using the two different pieces of equipment and showing us the different samples was awesome. Thanks
Let me tell you something.
You are a car doctor. Really you are amazing.
The best one who move step by step and analysing the root of the car problem with an evidence .
Thank you doctor.
Is it the pig-tail fix the problem or the truck still need alternator like to see after fix
Excellent video. 2007 Mustang GT with 70,000 miles.
I am getting the same code and same symptoms.

That was very helpful. I have a Pontiac Torrent with a po 621 code. I’m gonna check it with the scope.
Good Afternoon Realfixesrealfast take care and have a great day 👍
Thanks 👍

Always great information to be gathered here!

Great video as always sir. It's great to see you again after a long while.
I wonder if yoy put a compass by the wire then wiggle it? perhaps the field would swing the needle back and fourth while wiggling it?
It could be but you are barking on a wrong tree!
you also can hear the difference in the motor under load sweet video
So much talent , thank you for all your videos they are awesome
been a while. glad to see your back, nice diagnosis.
Good find and use of the Verus.
For all that matter, you can just wiggle the connector and listen for alternator belt load fluctuations...
Yes you can , but seeing it on the scope lets you know for 100% sure that you know what the problem is . A good tech will confirm the problem before making the repair . No guess work with a scope .

Nice video 👍
great video. great to see you. long time again . thanks a lot.
you did a lot of wiggling in this vid to find the evidence.
P0622 means that it has a alternator connection issue than? My battery light has been on for 2 weeks and I can't figure out the issue. The alternator was testing at 14.05. My alternator is at the bottom so it's hard to check the connector down there.
great video, Thank you. where can I get a scanner like that one?
Did the new connector fix the problem? I am working on a 2008 Silverado 5.3 with the same problem and code.
Nice video Duane.....i guess new loom section cured it....Fred uk.
i had a. similar issue p1637 and p0622 Haness was ok i swap alternators because ei had a new one laying around and i had the old alternator and battery tested and both came back good and i was looking at my data stream for the f terminal and it had a constant pattern but it would suddenly drop to 0% then right back up to 5-89%ish any ideas I tried wiggling my terminal also but no noticable drop in the scanner
I wish my car was messed up so I could take it to you and have it fixed.....real fast.
Thanks.
glad you are back
Great video!!
The battery light is flickering off and on.... toyota corolla 2010..., its gone through two batteries in one year!! The car starts but if i test the battery its losing charge .... why?

If the signal was coming from the ECM, why did the signal drop out? if the connection between the plug, and socket is bad, you would still have signal at the plug, where you are probing it.
Because he has the scope on the signal return wire . Your are seeing what the alternator is sending to the ECM .
Look at the diagram in this video again.
+myboy051 that makes sense, but it is not what he said.
Okay, you clearly have a connection issue at the alternator. How are you determining that it's the connector and not the alternator. Could be contacts on or in alternator.

Do you have a video on a 2008 GM. 6.2 codes p017 & po174
Great Experdience
Nice job Duane =P
thank you so much for this
thanks for sharing ...
thank you
Thank you ⭐⭐⭐⭐⭐👍
brake fluid is low and dark 😁
can we see video for GM 6l80E rebuild
Could a bad alternator set that code?
aw
Thought this was real fix "real fast"
