Clock problems!!!

[stravi757]

I am having trouble with my clocks. A while ago I started pulling a clock from a Z every time I went to the junkyard. Determined to find a working clock I kept trying different clocks over the past few months. None of them worked, Two of which were quartz. I know have I think 12 clocks, and none of them work. I know they are notorious for going bad, but 12 and no luck?!! So I had a perfectly good working Quartz clock which was replaced by my boost gauge some moons ago. I thought to myself, this one has to work, it was working perfectly when I took it out. Wrong, didn't work. So today I picked up another quartz clock, tried it...nothing.

 

Is this even possible to have this many bad clocks. Am I not doing something right when I put them in, Do I need to hit them first or something.

And yes, I checked to see if I was getting power at the plugs;-)

I would be surprised if they worked a month after the car was sold. you could buy an autometer clock and just swap the guts over.

My '77 has a working clock.

A "timely" answer. Tic toc tic toc.

Try to remove the casing from the clock and clean all of the crap out from the inside. Then lube accordingly, I bet you will get more that one working this way.

Good luck.

I believe there is a capacitor in the clock. It's electrolitic. They tend to dry out over time and go bad. Try getting a replacement and see if that helps.

The older 240Z mechanical clocks, can usually be cleaned up carefully, lubed, and made to work. Also, the 77 and 78 clocks are more reliable solid state. Ahem. Are you sure you have 12volts at the clock wires? Had to ask.

I got a clock out of a '78 280Z (one of the solid state ones), put it in my '71 240 about three years ago (it bolted right in) and it's worked flawlessly ever since.

I have a working Quartz clock in my 280z. The only problems is that the time is not accurate. It falls behind all the time. I set the clock at 5:30, 5 mins later, the clock only had moved 3 mins. Is there anyway that I could fix this problem?

 

 

Thanks

Or you could do like I did and put one of these baby's in....

Love it! Big and easy to read, trip/stop functions, needs no power(except

a couple of twists to the stem winder every two days or so), mucho coolness.

No, you don't need to run 27v to for any reason- that's for Angels 45 & -40c!

No, it won't fit in the hole without some kind of adapter- my dash was already

shot ta hell anyway. I just used a bigger hammer....and sickle.

Oh, I crack myself up somedays..

Tried the link, but got clasiczcars error message.

 

 

Is this the capacitor? If so, does anyone know the specs for it?

 

 

 

My clock runs when I bypass this. Don't know if it's accurate, but the gears spin.

That is a resistor.

Colored bands represent

the ohm measurement. See a standardized resistor color/value chart.

I don't see a capacitor in your pic.

Thanks Jasper,

The resister seems to be all that's keeping it from running.

My 1978 quartz clock started losing time last summer. I had a spare, so took it apart to see what could be changed. There are only 5 components on the circuit board as follows:

1. 16v 100uF capacitor (Nippon chemi con CEO4W)

2. 200 ohm resistor. (Cant figure out the exact specs. It has 200 ohms and either I or 1 JL6 printed on it and its green. Its about 11 or 12 mm long, which from read I have read may mean its a 1 watt??? and 3 or 4 mm wide. Under it on the board is printed R for resistor presumably.) Not sure what kind of resisitor it is. 

3. Next to that is what I'm guessing is a Zener Diode as it has ZD printed on the board next to it, and has a band on one end. Its white with a red band and has either LX or X7 written on it.

4. I think a crystal oscillator labelled 4194.5 TOYO COM 7C4. It has XTA printed on the board next to it.

5. A 16 pin chip that I think the symbol on it may be hitachi? HD44001 7K 33.

 

The capacitors are all over Amazon, so not a problem to find. Does anyone know if any of these other parts can be sourced anywhere? I would like to replace with new as much as possible while I have it apart.
