You need to replace all your plugs at once and you should have 10.5V plugs in your 12V slow glow system:

NGK Y147T

If you're measuring at the glow plug buss bar, you should have the same voltage at all points.

i replaced all the plugs last week and its still reading the same as what i stated before, does anyone have any idea why the motor doesnt start easy?? everytime i wanna start it now i have to run 2 bits of wire from the battery to 2 of the plugs and then it starts.
any help would be great,
thanks mitch
