ARB Twin Compressor Issue

[w113msh]

I have an ARB twin compressor installed along with front and rear ARB air lockers.
The compressor is working and engages/disengages my air lockers; however, when I plug my hose into chuck to air tires, its not pressurized or working.
Thoughts on troubleshooting or issues?

Assuming you have a manifold on the compressor with separate solenoids for each locker? There is another port for straight air (no soleneoid) that should have air if the compressor is running. Need a little more info about your setup.
