Ground wire has voltage

[Grimzly]

So this isn't related to Nest, but curious about theories on it. 

The Nest stat was reporting faulty ground wire, but still worked fine. Curious about the ground, I measured with a multimeter and it was reading 8v coming from the furnace PCB board.

I decided to sever this and ground to another ground in the wiring, but I am interested why I have this voltage running through the ground wire. The pcb not grounded or I guess I have a short somewhere.
