I managed to get hold of an Amp from my daughters boyfriend today and plugged the beast in for the first time.

Good News, on the bridge pickup, whisper to a scream..very happy, huge amount of variation across the volume and tone controls, absolutely no unwanted hum, couldn't have asked for more.

Bad news, on the neck and in the middle of the 3 way switch, nothing, dead.

All my earths appear good, I've triple checked the wiring diagram and everything is going where it should.

Without ripping everything apart just yet, where would you suggest starting to hunt down the issue?

I do have a very simple multimeter, nothing fancy.

Cheers
