PicoScope 7 Automotive
Available for Windows, Mac, and Linux, the next evolution of our diagnostic scope software is now available.
Well that is not true ! I am in the Aftermarket and did not tell you that ?The aftermarket telling me that silver calcium batteries were not required. Auto-electricians telling me that they had repaired faults in the alternator and that it was now working fine, only to find that later the battery still discharged. I fitted an OEM alternator from Ford myself, and a silver calcium battery myself, and now I can see the charging system works perfectly. The aftermarket told me what they wanted me to believe!
Actually it might be better if you read the posts properly the first time before words get twisted around. Regarding the oil cooler, if you read the thread properly I said that I thought the oil cooler was the cause of the problem even before I went for the car.Engineers said it had tested OK. Clearly the evidence proved they were wrong. A new OEM oil cooler fitted cure the problem.Iver wrote: ↑Tue Aug 13, 2019 6:53 amWell that is not true !

With your posts it is always about this "Auto Electrician" "Advised" me this and that. Then a "Master Tech" "Advised" me the other.
Not my business where you find these people but generally the information in the post is, at best, questionable ! Every time !
Your Evening Seminars with Snap On are not going to make you anything of use when it comes to basic knowledge and understanding system function. The scope wont make a technician work good.
You have to be a technician to make the scope work !!
There in lies the problem. Premature purchase of scope possibly ! We are still struggling with fitting the right battery first time. It is an indelible blemish on the trade and that rubs off on all of us. That is not right!
Taking Cylinder Heads off twice then find a fault in the Oil Cooler ?? What does that say to your paying customer ? and the motoring public ?
You don't know what you don't know. The basics are very near to non existant, time to focus there first.
Thanks Speck, yes your correct and yes I have proven it to be the leads, however I still have a problem on cylinder 4, reference the firing line and the burn KV. I might get chance to look again tonight. Every day is a learning curve for me.speck wrote: ↑Tue Aug 13, 2019 8:36 amHi technician, I'm looking at your first post (screen 7) you are running at around 800rpm.Your cyl.4 shows
some odd behavior which is a characteristics of pico's secondary leads. The data is not valid anymore when
you see those jumps. There are 10000:1 leads available which are a lot better, but do it sometimes too .
Waste spark system is best checked at idle since you have the advantage to see a spark under no compression.
I hope that helps you a bit
Really ?? Then why don't we check spark with the spark plug removed ? In atmosphere !!Waste spark system is best checked at idle since you have the advantage to see a spark under no compression.
Iver, something wrong here mate, really!Iver wrote: ↑Wed Aug 14, 2019 5:34 amReally ?? Then why don't we check spark with the spark plug removed ? In atmosphere !!Waste spark system is best checked at idle since you have the advantage to see a spark under no compression.
I have always seen compression lower at higher Rpm then at idle too. Something not adding up here !
First of all I'm talking about waste spark system. When you see compression and exhaust firing on the screen,Iver wrote: ↑Wed Aug 14, 2019 5:34 amReally ??

Which I have had for years, in fact I had pressure transducers and flow meters long before Pico bought their versions to market.If you had the WPS500x pressure transducer from Pico, and used it for engine testing,
Completely wrong. That statement is only valid if you do the Dynamic Compression Test INCORRECTLY with a conventional analogue gauge.Therefore a dynamic cylinder compression test will increase the cylinder pressures when speed increases and not therefore reduce.
I hope this brings a little understanding to the subject.
Yes. but not ignition basics ? This is not Honest John Forum for the ,,,......Please remember we are all here to learn from each other,
Clearly not !!and common sense isn't a flower that grows in everyone's garden.
