Thanks Kenny much appreciated.
I have snipped the wires to the neck pickup, leaving a small piece of the colour- great suggestion.
I still get no reading from the neck pickup with it disconnected- (the same as when using posi 2 on the rotary).
We can safely assume it is an ex pickup.
I am pretty thick when it comes to electronics, so sorry, when you say in the previous post,
"The circuit shows the bridge pup works in all but position 1...
Position 4 tells you that there might be an open circuit on one of the coils as they are supposed to be in series, which means all wired in a straight line - wire/coil/wire/coil/wire etc in-and-out..."
Are you saying there could be an issue with the bridge pickup?
Now, I see there is a restored Ripper pickup on US eBay but doesn't say whether neck or bridge- says it is 6.5K. Seymour Duncan do what they claim to be a direct drop in and it is stated to be 7.4k. I am leaning towards the Seymour Duncan. Are there any issues I should think about using a Seymour Duncan neck pickup with the existing Gibson bridge pickup- remember... I am electronic thick. Anyone used the Seymour Duncan replacement pickup?
PS. I have sent a question along these lines to Seymour Duncan.
