Sorry guys for the poor explaination on my behalf (English is my second language next to stupidity)
The wire was half out of the connector. So when I put it out completely the right hand string went out. It was just on first observation I thought I got lucky and saw the wire out and that would have been the problem. Sadly I wasn't that lucky. I've looked at the manual and the pinouts don't seem to match what I have and so would like to check with another T2 owner as a precaution.
That GI's have worked in the past so wiring was not an issue. I just don't know whether a wire has come out while at my son's home and he had reseated it in the wrong pin location or not?
thanks for your thoughts so far
