Quick reply here, see if I've done this right.
I touched each wire separately (blue,white,red,green) with both the red and black test leads.
The multimeter was set on Ohms, 2000k.
Each wire had the following results:
Red: 500 - 1500
White: 500 -1500
Green: 500 - 1500
Blue: 500 -1500
I guess this means that I have continuity throughout the turntable and this is a phono issue?
