Having a spot of trouble. Am wondering if you experts here would be kind enough to offer me some guidance?
Please find some gauge readings and other info at the following link.

Oops time for some math.
Need ambient, application, (make model year), vent temp, and what work has been done recently, and did you use an electric motor powered vac pump

Johnny, Your high side hose isn't hooked up or something, both gauges reading the same pressure

Detroit AC you made me see the light!!!
There is after all a psi scale buried in there!!!!
"Running - @ around 2000 RPM" is the reading that is most important.
Are these pressures with your gauge valves (big knobs) open or closed, if open the dials could be cross reading because the flow has intermixed
Could also be grossly undercharged.
Try making sure knobs are closed and try again.
The only time you have both knobs open is when you are vacuuming down, and you have your pump hooked to the vacuum port, and pull both sides down together
