Had a similar experience with my wind inflator. Was running a MK2 1st stage off small hip mounted cylinder for wing inflation. I was still waiting for delivcery of an OPV, but still diving with it nonetheless. Turned on the bottle one day and the inflator control started continuously popping and over filling my wing.

Checked the IP, which was off the scale.

I rebuilt the stage and installed and the OPV. No problems since.

Cheers
