I just finished installing a PacBrake. I turned it on for 4-5 minutes but it never shut-off. It's not connected to the ECM but strickty manual control. My question is this: How long should it take to fully pressurize the 1/2 gallon tank from empty?
Is your the PRXB? and you are talking about the compressor not shutting off? You must have a leak, mine takes maybe a minute to fill up the tank.
