Problem with Red/green light

[Sweet6]

My TTA with Razors Alky seems to have an issue with the red/green light. It used to work fine, but now is kind of flaky. I press the test button for a while to prime the system. But the boost will hit 15-20lbs and the light stays red. The tank is near full as well. Any ideas on what I should look for?

TIA

Put the knob on 8. Now press and hold the test button. Should go red.. then green. Should stumble pretty hard as well...then.. If you go into boost, should also flick red then green pretty fast.

If so.. try setting your gain knob a little higher. If not.. call me, more than likely have debris inside the pump head.
