i fix a lot of zafira a and b models,they suffer badly from water damage,rusty cables ,i do the same tests too,rust makes a nice resistor,for voltage drop,like when is 12v not 12v,when lot rust on cable joint and can pull 12v on test meter ,but add high load,say 55v bulb ,h7 ,will be dim,as rust stops the flow of electric,i got opcom and snapon ultra for my every day code reads,but after watching your vids,now have forscan,on my laptop,nice bit kit,and now seem to have to fix 2.4 and 2.2 transits ,rwd and fwd models,forscan is great,also great forum too,strange how i fix cars ,vans all day and come home and watch machanics videos,but there is little gems of info to be found ,would love a toolbox tour of your box ,always love to see another mans tool box set up,my friend works at renault trucks and he has 3 roll cabs ,plus breakdown box ,big spaners and sockets too,my other friend tony is in the rac ,he loves it ,cant stand being in a workshop all day ,or mot ramp
Thanks for the comments. A tool box tour wouldn't make a good video, im not one of those with 3 of everything and most of my snap on stuff has now gone. I've got minimal tools, having spent a few years on RAC myself, you learn you dont need many tools. Working on one brand mainly, you get away with less tools
Years ago that fault would have melted the choke and throttle cables, also why not slap a bit of vaseline on those connections? great informative video, thanks.
And that is how you diagnose a alternator fault like a pro 💪, a lot of garages would have just changed be the alternator and would be scratching there head afterwards, 😂
SUBSTANTIAL SY DIAGNOSTICS Impressive video thank you very much for sharing with us. Take care and have a great Happy Easter 🐣 holidays God bless you SY Diagnostics From Nick Ayivor from London England UK 🇬🇧
Awesome video Steve. Do you think maybe the ESC fault was the front wheels of the ground rotating giving the ABS some duff information 😂😂😂. Top volt drop demo even the dealers know the secret of success
Excellent find there Steve Volt drop testing is the best in my opinion 👍 Keep the videos coming enjoy watching all your diagnosis. I have a question, Steve I’m struggling on a job didn’t know if you had any ideas Transit connect 2018 1.5 tdci 17 k on the clock Code P2279 intake air system leak bank 1 ,goes into limp mode when RPM is raised over 3000rpm. I’ve smoke tested the intake there’s no leaks anywhere, tried another MAF sensor , compression all good , updated the PCM , the MAF and Desired readings are not in sync with each other , Desired is 3times higher ?? Difficult question, any idea’s Steve.
Does this throw a fault code? I'm getting 062104 on my 2007 astra h and intermittent battery light. Sometimes I then the car off and on and it goes away again Plugged obd in and getting 12.5v on battery and 14.25v with engine running.
I could have but when videoing whilst doing the job and keeping one eye over my shoulder, it sometimes easy to forget a part to film. I'm not afforded the luxury of free time /space to film. These are real jobs
Why would GM think that it is a good idea to ground out the main ground to the starter when water from the road will rust it out they should do like most cars do and have it below the battery tray where it would be protected from moisture plus it makes it much easier to clean it regularly if you have to.

Vehicle electrical basics but always good to see and be reminded how it works
Top job Steve , a proper methodical testing there , back to basics sometimes enables one to find the fault easily, great result there 👍👍👍

Did that myself, changed an engine in a Bedford van forgot the earth strap and the choke cable let the magic smoke Out!
Good methodical approach !
Another interesting and informative video Steve. Really look forward to seeing these videos, keep them coming.
Great video and seem like common issue this one have come across same issue at least three times up until now
Thank you for video and happy Easter

Top volt drop demo even the dealers know the secret of success
Yes, I wasn't too concerned about the ESC warning. It was my RAC days that taught me volt drop...15 years ago
Very helpfull and informative. Thanks
Hello, I'm a bit confused on what the expected voltage reading should be? and what the faulty voltage thing that was discovered?
Good video Steve.,I’ve had that exact fault mate
Excellent find there Steve
Volt drop testing is the best in my opinion 👍
Keep the videos coming enjoy watching all your diagnosis.
I have a question, Steve I’m struggling on a job didn’t know if you had any ideas
Transit connect 2018 1.5 tdci
17 k on the clock
Code P2279 intake air system leak bank 1 ,goes into limp mode when RPM is raised over 3000rpm.
I’ve smoke tested the intake there’s no leaks anywhere, tried another MAF sensor , compression all good , updated the PCM , the MAF and Desired readings are not in sync with each other , Desired is 3times higher ??
Difficult question, any idea’s Steve.
Have you checked EGR? There is also an intake hose that splits between intake manifold and the plastic pipe (but should show up on smoke test)
Does this throw a fault code?
I'm getting 062104 on my 2007 astra h and intermittent battery light. Sometimes I then the car off and on and it goes away again
Plugged obd in and getting 12.5v on battery and 14.25v with engine running.
You could of volt dropped the starter ground (stud and nut) the same you did the battery ground up top. Great video non the less 👍
I could have but when videoing whilst doing the job and keeping one eye over my shoulder, it sometimes easy to forget a part to film. I'm not afforded the luxury of free time /space to film. These are real jobs
Brilliant video
Nice work. 👍🏻
sorry excuse my ignorance how could the car start off the key if the main battery to engine ground was bad ? but yet not charge? Thanks .
It didn't start I had to jump start it to get it into the workshop
Excellent video 👍 👍 👍
Nice!
Not that it realy matters, but that's a corsa E ot a D, but they both use the exact same earth cable set up anyhow
Thanks I wasn't sure. I googled corsa d and ignore looked the same
Can you send a picture of your ampere Meter. I would like to have same as yours
It's about 15 yrs old so I'm not sure if it's still available. Uni-t do some quality items for the price
Thank you very much for your reply

Nice find. You leads are on backwards 😛.
Yes I mention that 😆
@@SYDiagnostics only about 3 times. Nice work. Not easy to do while filming.
@@d.d4184 as a rule it doesnt bother me seeing -12v, but when on film it has to be correct or at least pointed out. I'll try harder next time lol
That's a corsa e mate
😉
