de bug a small analog circuit grounding issue

i have a existing schematic, pcb layout and off board wiring design that functions perfectly on its own. But when used with a non isolated multi 9v power supply, its will short the power supply out.

im sure this is a small, quick find, obvious problem, but need someone with a fresh mind!

schematics, pcb layout and off board wiring diagram will be supplied, just dont want to post it up on here just yet as its a product
