I can highly recommend getting the book by Gerry Hayes if you haven't already.

It is the best guitar wiring guide that I've come across.

I second that. Anyone playing around 'under the bonnet' so to speak, should definitely have this book by their side.

I second-second it.  A great book that covers a huge amount of ground.  

Also, sign-up for his weekly emails for more free, but really useful/valuable, content.  Gerry seems to be one of the good guys.

👍

Thanks Brian. That's good advice. I'll do that before ripping it all out and starting again.

Hi again Chris,

Was just thinking about your electrics problems, the most likely culprits are probably the volume and tone pots and the pickup selector switch. Try cleaning these with contact cleaner spray, it might just get some life back in the system, I did just that recently with a friend’s Strat copy that had been sitting unplayed and neglected for years and which he didn’t want to spend too much money on. Might get it going enough to assess what needs replacing.

Brian.

I picked up that book mentioned earlier, so I'll be digging into that while I figure out what I want to do with the electronics as I rescue the old Yamaha.

Welcome to the community from someone even closer, I live along the road near Falkirk, although I'm a bit further west just now over in Argyll.

Welcome to the community from someone even further north!! Sure you will find answers to all of your questions. Happy soldering👍😃🎸

All the Best,

Brian.
