Your gauges aren't hooked up right! You don't know what the pressures are doing that way! I'm gonna go out on a limb and assume you put the puncture valve on the small pipe stem sticking out the side of the compressor? The one that is just a couple inches and goes to nothing, with the end sealed? This is for the low side. The suction side. Connect your BLUE hose from the left side of your manifold to this. This will tell you what that side is doing. But you used a puncture valve. We only use these to evacuate systems. You can't leave it on, as it WILL leak, and you can't remove it as it has put a hole in it. If you have the tools n training I would recommend recovering the charge, brazing on some ports (remember to remove the Schrader valves from them first!), pressure test the system, pull a good hard vacuum, and weigh the charge in to factory specs. Then you KNOW you're good. With small systems like that, if you added that whole can, you've likely far exceeded its capacity.
