I have a new 6 lb 150 psi compressor and once the tank is full, it shuts off but the regulated pressure reads "0" with no air flow to the valves. I first bought it a few months ago and when I decided to use it, the regulated pressure didn't work. I exchange it for a new one two days ago and the same issue occured. Is this a connection problem or is this just a bad tank?

maybe you are reading the gauge wrong
the tank gauge and the regulator gauge will read the same but the gauge that reads when you adjust the regulator is the out line pressure to be n maintained during tool use
The pressure regulator on an air compressor is designed to let the pump motor run until the pressure in the tanks reaches their safe level. While you are using the air the pressure drops in the tanks until it reaches the level where the pressure switch turns the motor on again and refills the tanks to their rated level. The pressure where these two things happen is usually with in ten psi above or below the rated levels because few regulators are so precise and are affected by temperature that they turn and off exactly at the rated pressures. If a pressure regulator is damaged or broken it is possible for the tank to either reach unsafe high levels or not turn on when the pressure drops to where it should restart the motor. If you are in doubt, have the regulator checked or replaced as overpressured tanks are very dangerous.
Hi scooterb88...
Sounds like your pressure regulator needs adjustment...
Turn the knob on the pressure regulator clockwise and you should start hearing air coming out of your hose...Once air is coming out, remove your hose and keep turning the regulator till you get to your desired working pressure normally around 90 psi...leave your pressure regulator at that setting and it will stay at that setting.
Please take time to rate me
150 lbs is the amount of pressure in the tank. When you connect a nail gun for instance you cannot nail everything at 150 lbs of pressure, it will blast through. The regulated pressure is at zero because you have the ability to regulate it by turn the know under or beside it to increase the output pressure to your desired amount. I was building a shelf last week and set my regulated to 80lbs with a brad and it blew through the panel and stuck in the floor. After you get to know your nail gun you will be able to regulate it between 60 and 80 depending on the type of wood. Panel - 50 lbs, Oak, 90 lbs, etc. Pleas remember to rate this solution high if it was helpful and explained it to your satisfaction.
I dont know if it is like mine,but if you can let the air out of it and remove the regulator knob,and it`s components,you may can set it to just to be open all the time,in other words,by pass the control knob valve.Shout back at me if I can help.
Usually you cannot adjust the cut out pressure of the tank/motor itself, this is why they have regulators, which regulates the pressure flowing down the air lines (regulators like these dont regulate actual tank pressure cutout). To regulate air flow using the regulator knob, you actually have to have air flowing through the hose while you make the regulator/pressure adjustments as regulators regulate pressure DOWNSTREAM from the actual regulator itself.. so air flowing through is a must. Attach an air blower or something similar and let air start flowing through the hose. Now turn your regulator knob in the "-" direction to decrease regulated pressure. It is best to bring pressure all the way down to "0" first, then open the regulator up (by turning to the "+" side) and pressure will rise until you get to the desired pressure needed for the air tool in use. The tank pressure will still be between 80-125 PSI as the motor regulates and keeps the pressure in the tank between these values automatically, but your line/hose air flow pressure will remain at the regulated pressure (say 40 PSI or whatever you set using the regulator knob).
