Where are pots for adding R-14 to AC system?

[Markie]

Had Stallion out this afternoon. First time in a while. Of course, it's 90+ outside so I thought I'd run the AC. No cooling. Took me a while to figure out the Vintage AC setup & still, no cooling. Confirmed at home that the compressor was not locked up, so the next option was to add refrigerant. Couldn't see the low & high pressure Schrader ports for adding R-14.

Has anyone pursued this task and, if so, how accessible are the high/low pressure ports?

i guess you did look and see if the compressor was coming on not,it does have a low pressure switch if to low.

Results

Placed gauge on low side port: read ~ 10 lbs with compressor running. Shot 12 oz R-134A into system & low side pressure rises to ~ 30 lbs & cooling is now coming from vents. Put additional 6 oz into system & low-side pressure up to 40 lbs.

For all who replied, let me say thanks. Saved doing a hand-over-hand analysis of the A/C lines.
