Having got the car back from Culverlands and looking so nice it seemed a shame not to liven up the new switch panel by having a go at fixing the clock... I had discussed clock repairs with Kevin (Birch) about 5 years ago but had been somewhat intimidated by the prospect of dismantling it, however, as Elaine pointed out, since it wasn't working anyway I could hardly make it worse. The clock in my car (April 1969) is a Smiths Jaeger with front adjuster and speed regulator (as below).

Following the discussion with Kevin I was expecting to find more obvious contacts (Kevin's car is 1968 I think) but was confronted by this arrangement which seems to be some sort of spring loaded diode with a mechanical connection to the balance wheel. The plastic housing for the diode and spring had cracked and split and when I removed it it fell apart into 4 pieces. What appears in the picture is the plastic housing after I glued it back together and strengthened it with some plasticard strip: this repair didn't work at all.

However, I found this website:
https://www.clocks4classics.com" onclick="window.open(this.href);return false; on YouTube along with some really helpful videos and bought their repair kit for £62 including postage. What you get is a small circuit board (which replaces the diodes / contacts) and some other little bits and pieces. Fitting the circuit board is a bit fiddly as a lot of the clock mechanism needs to be removed, some pieces discarded and then the whole thing reassembled; however, the video walk throughs and downloadable illustrated instructions are really clear and so after 15 years we now have a working clock which seems to be keeping quite good time!

I haven't added a detailed description of how to fit the circuit board as I cannot improve on the instructions and links on the website (link above). I really do recommend Clocks4classics - the owner (also Mark) seemed very friendly and I received the kit by return of post. Hopefully this will be of interest to other members!
