Nigel,
Shielding may keep noise / an offending magnetic field in or out. Sort of like a tube which keeps water inside or outside water from coming inside the tube. Shielding can be different %'s, wire meshes or braiding are have a basis for use. Maybe save yourself some agrivation and just replace the wiring with shielded cable. You will find 100% will have both a foil wrap and also
a braide. The ground provides an easy path for the noise or interference to travel and should be an independant ground system.
