How long is it?  I'd expect it to be 3-9 inches if it's meant to be a 
ground wire that is attached to something else on the chassis.

I would also have significant worries about ground loops and / or sneak 
currents.  Both of which can be quite dangerous from an electrical and 
safety perspective.  As in more amperage than the wire can safely handle 
turning the wire into a heater that can melt insulation and start fires.
