I have tank, scale, gauges, and vacuum pump if you want to try a different system?

I got it out, replaced with one of the variable kind. Replaced the accumulator. Evacuated and recharged, it did the same thing. I now think the machine is putting in more than it says it is. Im not sure why I did not realize it before, but in a static condition, the low side pegs, and the high side will sit at about 250. It should be sitting at about 70-90 or so on the low and high side static. I think its just WAY overcharged. I may have the machine set wrong or something. It is set on lb, not kg. I think the calibration was off on the scales. To check the accurace you are supposed to take the tanks off, put in a certain mode, put something on it that you previously weighed so you know the exact weight and check it. It was reading about 2lbs high. Of course with the tank on there, it showed to have about 2.5lb of R134 in it. I do not think there was any refrigerant at all, if so, not very much. I pulled the lines off and opened the valve, and alot of air came out I assume. If it was refrigerant, it would have gotten cold as it came out. This air did not. So I went thru the calibration procedure and after setting it, it seems to be reading correct. I did this calibration last time but at the end of it you are supposed to pull a vacuum on the tank and machine before adding refrigrant. I did not do that last time. I did this time. I suspect the 134 tank m ay have leaking valves though. I decided to leave it on the machine hooked up to the low side and see if it leaks down. The guy I bought it off of said it seemed like it leaked so I knew that going in. I guess if it comes down to it I will order a new tank for it. Can you buy just the replacement valve assembly for the tank? Anyway, that is my update. After I recover it again I may try it with the machine 1 more time, but if that doesnt work, I will do it the old fashioned way with cans. In this whole mess I know I have lost some refrigrant, probably from that leaking tank. I will probably take care of that before I do anything else with it. -- Kaleb C.
