The Stop Clock (Part # 27385 E4100) is not working in my 1973 Fairlady 240Z. I wonder if the Oscillator (Part # 27395 E4100) may not be working. I have not been able to locate parts or find some help on this one. Has anyone got any ideas or working Oscillator or Stop Clock??

Regards Jack

Hey Jack,

Take a read of Enrique's fantastic clock-fix topic here: http://www.classiczcars.com/forums/showthread.php?t=18442

This may help?

Not sure Enrique's fix would work because I believe he is talking about the Rally-type clock with the separate oscillator box.

Of course. Sorry.

Oscillator boxes are worth big dollars. I heard that they are "pretty much unrepairable" once they stop working, but I'm sure the experts will chime in soon. Have you tried asking a clock shop or intrument repair shop if they could fix it for you?

Alfadog and Go240Zags - Thank you for your input. By now Alfadog, you will have worked out I have been working hard to secure a certain Fairlady brochure - cost nearly as much as the car!!

The Clock is a stop clock, and does have a separate Oscillator box mounted on the firewall above the passengers's feet. I have not tried having it checked over by someone. I figured it would be hard to find someone who knew what it was and how it functioned.

I look forward to other responses.

Regards, Jack

I just had another thought. We own a 1978 Cessna 310R twin-engined aircraft that we purchased in May 2004. So we have connections with people who may have knowledge of sophisticated 70's electronic equipment!!

We purchased the 310R "on the net" from the eastern part of the USA. Our son helped fly it out to Australia, picking it up in Defiance, Ohio. That was some trip!!

But I digress!!

I've been trying to find an oscilator for the past 6 years! PLEASE, PLEASE! Take your oscilator to an electronics man and have him "Back Engineer" it. I'll pay half his fee and full for a copy for me!!!

Jack,

Usually, the oscillators are either living or dead. There's no in-between.

If it still 'hums' and gets slightly warm - rather like the reassuring behaviour of an old valve radio - then it is alive. If it is quiet, then it is most likely dead I'm afraid. Bringing them back from the dead is very difficult I'm told, as the internal parts that can be replaced are not the ones that cause the problems...........

Somewhere I have a Nissan-sourced circuit diagram for the oscillator internals which might aid replication, but I can't find it for the life of me. I'll have to see if I can dig it out.

NICE car, by the way.
