I'm really an idiot when it comes to troubleshooting problems with electric guitars. I'm using a washburn and it seems that all my pickups are not working. I'm not sure how to go about fixing it.

Could anyone advice on where to lookout for possible cause of this problem? I unscrewed the cable inlet to my guitar and found that the wires are intact. I'm not sure if the problem lies with the pickups (i doubt so as all the pickups are not working and I just bought a new cable) or some wires linking to the pickups. I'm not sure how to dismantle the pickups to check as well. Please help!!
