Animation of this issue would be a great teaching method. You could show the restriction in the line at any given place - Condenser/TXV/Drier and so on. That would really help in understanding on how the A/C compressor interacts so to speak with a restriction through pressure or suction. I wish someone would do this.
In this video The high side gauge NEEDLE is actually reading zero...as the low side needle is using the CORRECT POINTER END OF THE NEEDLE >> your using opposite reference points on the pointer needles. easier to unhook a couple of hoses and blow air thru the system..
I am sorry Mr. Silver Chief, but I watched the video and everything is correct as stated. All pressures in this video is taken from the larger side of the needle, the correct side. The high side needle is reading between 40 and 30 psi in this video. I am sorry if there is any confusion. The pressure reading may be hard to see if viewing from your phone. PP
@@ProfessorPentane Thanks for the response..Ok Im referring to 2:28 0n the video control track..RED needle short side is at 1 o'clock position. the high side is down in the red where the long side of needle is pointing at 2:28 ....low side BLUE needles long side is well into the gauge numbers.
65° ambient temperature your low side should be at about 42 to 45 and your high side should be around 180 or 200... ASE certified here what you're showing me looks like an undercharge system did you verify that it is fully charged did you evacuate it and put approximately 2 lb of Freon in it... Fully charged system with a restriction will suck the low side into a vacuum in the high side will go right up to three 400 PSI I don't know what school you went to or where you got your certifications..
Well George, your comments are rude and unprofessional for an ASE A7 certified technician. I hate to embarrass you, but you have the wrong information. When there is a low side restriction, like at the TXV, the low side will go into a vacuum and high side will also drop. I have lots of videos to prove this on my channel, you should watch a few. Try putting Co2 or use a Duster Can of R-152a on the power dome while the A/C is on. The TXV will close and show you the low side drops and high side also drops. A restricted FOT will also not cause the high side to go to 400 psi. You are simply wrong my friend and I can prove you wrong . Just watch my video titled "How to test the H valve with Co2. You made my point on why I have this RUclips channel, there is simply a lot of wrong information out there. Just to give you some of my street credit, I have been teaching A/C classes for over 30 years. I have taught for Chrysler for 15 years and 1,000 of techs have attended my classes. I am a current Professor of Automotive Technology at one of the top ranked automotive schools in the USA. Yes, I am A7 certified. I am the expert in A/C! Plus, I am writing a book on automotive A/C. Do your have more street credit than I, are you an A/C engineer? I don't normally respond to the hundreds of post on my channel, but you quested my credentials. Professor Pentane.

Thanks again for sharing your video, I will have to watch a few times to understand it ...👍
If you had illustrations or even simple animations this would be way easier to understand
Hi Scott, thanks for a great video. So where did the restriction end up being located?

I had one where high side stayed at 100 and low side function normal
