how do i check the pick ups on my guitar?

Easiest way, if you know that everything else is working ok is to plug guitar into amp, turn volume up on guitar (and ap a bit on amp) and tap each pickup in turn with the metal end of a screwdriver as you switch between the pickups via the selector switch and make sure you can hear a clunking noise from each pickup - if they cunk, they are working.
