Hello Phil,
Thank you enormously for the information on the connector and cable, it explains a lot!....
So armed with this info, I took another look at the loco and tender. Now for the "red-face department!" .... I bought the loco secondhand some time last year and in all fairness it was described as a "non/rough runner" and the "cut cable" was disclosed. I sort-of half-heartedly looked for a cable assuming that as it had been "cut", it would need replacement.... Closer inspection has revealed that the cable has not been cut... It has been yanked out of the connector, the remnants of which are still engaged in the tender..... As I had not got my glasses on, I thought that this was an "eight-pin" connector....... It turned out to be a four-way connector and I was looking at the back end of the pins which are bi-furcated!!...... Do I feel a wally or what?...... It turns out that I have a few of these connectors as they are the same as the four-pin cable connectors used on the Stainz-type connector board. So at long last, I have the means to fully repair my Nicky-Frank, but I would not have been able to do it if you had not sent the above information...... Thanks a million Phil!!... I owe you for this
Oh, and next time, I'll put my glasses on!
Dave
