Alky test button pressed, light flashes green to red rapidly

[Boostian]

So this morning, Sunday fun day, took the Buick into work. Cold morning in Philly, about 55* out. Test the alky with the button while driving and takes a little longer than the usual 3 seconds to go green, then starts flashing green to red, back and forth. Rapidly.

I try it again, same result.

Ease into boost and red and green comes on like usual.

Try the test button again.....green red flashing quickly still.

Any ideas before I give Julio a call?

The switch on the pump is bouncing. Not an issue. You can add tension by turning in the allen screw on the pump. But that may lead to not going green at all when you hit test.
Or try the reverse, take a 1/2 turn out.
Light changes when pressure goes above 50 psi. It could be pulsing 45-55 psi. red/green/red.

Thanks. It was fine today on my way home from work. If it happens again I'll adjust the screw. Appreciate the response!
