Checking each switch I find one that I had not re-soldered back on. One wire was touching and making contact. A quick bit of soldering and presto!.
The old man and I were pretty proud of what we had done. He has come to appreciate what pins mean to me and I have come to appreciate that has always been there to help out.
Aquarius works beautifully but could do with a far more intensive resto, along with a better backglass. However, to me it has a special meaning that just got more special.
