Picked up a M322 trailer and hooked up the glad hands with the truck not running. The primary and secondary air gauges showed 110 psi but very little air flow was coming out of the emergency glad hand. Started the truck and then had a lot of flow. The trailer air system has a few very small leaks.
While driving the air gauges showed 110-120 psi but the dryer would blow off every 5 min. Seems like somehow a check valve isnt allowing air to the trailer air system.
