thanks brother for video. I can make that tool. so doe's it sound like I boogered up this ball valve? I vacuumed a few more hours gauges only went to like -24 however after about 3 hours shes still holding at -24.

Doesn't matter, that valve can be removed and it will not effect the vacuum, as long as the gauges are connected obviously.
not sure what happened yesterday when gauges won't go below -24. todays vacuum for 1 hour managed to peg the gauge down to -30.
.
could it be possiable I didn't snug the colored tubes fittings tight enough an thats why it wouldn't go lower than -24? today I used the vertical fitting of pump w/ my adaptor.
will check later to see if it holds the -30
think I'll call it ready to charge.
my plan is to jump the hi pressure sensor w/ paperclip
to ingauge clutch to suck in the 1st can of freon. replug in the sensor then add the 2nd can an hope she holds.
Like I said before, inches of mercury is not a very good indicator of vacuum. Maybe I'm biased, I use Microns.
I wouldn't jump the pressure switch, but do as you will I guess.

OK new plan will do quickie vacuum again Sunday, then connect 1st freon can let it suck in then equalize then start engine w/ AC on ,max hopefully the compressor clutch will ingauge an will suck in the remained of 1st can.
close low pressure valve at gauge (high pressure won't be open during this process). then attach the 2nd freon can purge yellow tube rotate can from horizontal (east west) to south let sys suck in all of can.
I don't have a thremonitior guess I'll just feel the coldness inside car.
undecided on attaching 3rd can just for a few OZ.s my small cans are 12OZ sys takes 24OZs
figure I can fine tune a couple OZs later.
I'd like my 1st can of freon to be the ezchill w/ leak stopper hope its safe to remove the dispenser an connect to yellow tube or should I just use regular freon?

Charge it with the can upside down.
Straight liquid into the accumulator. I don't give a damn what anyone else says.
You COULD add it all with a heat gun without even starting the vehicle if you wanted. But thats dangerous because the internet said so.
She sucked in 1st can of Freon I was expecting the sys to equalize halfway though 1st can then crank up engine w/ AC on max which would ingauge the compressors clutch to suck in remained of 1st can clutch never ingauged.
Same w/ 2nd can clutch never ingauged halfway though 2nd can I checked the electrical connection at compressor it was plugged in then checked the high pressure sensor (remember I was planning on jumping the sensor) well it was unplugged I didn’t see it unplugged it was hiding under the cruise control cables dam.
Plugged in sensor restarted engine AC on max clutch ingauged an sucked in remained of 2nd can.
Not sure where the second half of 1st can went same w/ first half of 2nd can?during this time blue gauge stayed around 3 o-oclock.
After clutch ingauged an sucked in second half of 2nd can blue gauge moved as I expected over to 10 o-oclock.34PSI Air is cold inside car.
Ambient temp was 82* 69% humidity.
according to my recharge instruction sheet for minium and maxium charge at a given temp. I'm a few LBs low on low side
82* falls inbetween there chart.
I believe high side is acceptable bc it's above 175 and below the 200.
not sure if I dare open a 3rd can? but I do have the ez chill can w/ it's builtin dispenser. still unsure if I can remove the dispenser and connect to the yellow charge tube?
Edit: this took about a half hour. Majority of this time the red valve was closed I opened it briefly was thinking maybe it was blocking the refill red needle moved a tad then I closed it prevent a back feed into can.
So where did the 2nd half of 1st can and first half of 2nd can go?
I have been taking notes so I won’t mess up the next AC.
plan to add freon either today or Thursday. it's 84*ambient so I want my guage to be much higher than current 34psi
my chart says for 84* 40-50 on low side an 175-210 on high side
look closely at my chinese chart they screwed it up! I believe this chart increments like 4* w/
all the presures progressly go up except 78.2* an 84.2*
I believe 78.2* is switched to 84.2*
still don't understand your chart for 85* 95psi? I want it to be colder where I have to not only turn blower off but have to turn blueness down also.
thanks for freon advice
corrected American chart
decided to go w/ just under 45 on low side 225-250 high side * never exced 250 hs.
pls suggest optimal presure for 84*
I posted a temperature pressure chart. That's the temperature that the refrigerant should be at a given pressure.
It's very close to charge with this chart.
If you go with 40 to 50 psi that comes out to approx 45 to 55 degrees you don't want that.
I'd shoot for 35 psi. And again the variable displacement compressor comes into play here. The pressure control valve will keep the pressure in range until you over or undercharge it.
