S470 humming after pup change

Ello all,
I have had some Ibanez Hot Grinders from an Ibanez S Prestige fitted to my Ibanez S470. Now the guitar hums when I am using a lot of gain. NOTE: This only happens with the bridge pup.
If I take the cover off and put my finger on the jack socket the hum completely disappears, if I touch the back of the tone pot the humming goes too, also there are two wires (red and white) that are taped together, if I squeeze them the humming gets louder.
The shop that did the job has asked me to take it back but I just don't have time at the moment.
I can use a soldering iron so if someone can point me in the right direction I'll have a go.
Phil

Re: S470 humming after pup change

sounds like a grounding problem on the bridge pickup to me, my first thought would be to remove and re-solder the ground wire from the bridge pickup.

but these things can take time, its often an intermittent fault that can be hard to trace,
if the shop will redo it for free it makes sense to take it back.
