Help! Ground issue Epiphone Blackbird

[godofthunder]

     I  have a touring pro's Epi Blackbird in the shop for a setup and solve a ground issue. The ground wire coming from the bridge looks like it was never soldered. I grounded it to the toggle switch and no hum comes from touching the bridge but I do get a faint hum when I touch the toggle switch. Anyone got a wiring diagram?

I don't know of a wiring diagram, but it really shouldn't matter where you ground the bridge, as long as everything is grounded to the output jack.  Traditionally, the bridge wire is grounded to a pot case.

The Blackbird only has a toggle so I grounded to that, I should be ok then
