How do I test a 280 clock?

    Recommended Posts

    I figured putting 12V battery (+ & -) to the blue and black leads should power the clock, but it doesn't move or make any noise. The guy I bought it from says it worked and says I need to connect it to the harness to work correctly. I plan on putting it in my 240, so I will be altering the wire harness anyway. I am just trying to determine if I have a working clock first. Any help is appreciated.

    Thanks. I will try that. I also should note that it says "Quartz" on the face. Does that make a difference?

    Remember it only makes a tick every once in a while (15) seconds?) I don't listen to mine much, but it does tick.

    I left it connected for a bit and the hands did not move. Do you agree that 12V (ground to black and positive to blue) should make the clock run if it is not dead?

    An everyday quartz time piece will tick every second.

    An older mechanical, wind up, self winding movement would normaly tick 5 times per second, however, some high grade hand made precision movements of the day could tick at a rate of 15 times (or more) per second.

    I tested a 240 clock in the same manner and did hear a ticking noise if listening closely. blue to 12v black to gnd. I left it for 10 min. and the clock advanced 10 min.

    I would say your clock is non functional.

    There were some threads on here about replacing the internals with a more modern component.

    That applies to clocks with a second hand. Ordinary car clocks tick less often like 6, 12, 15, or 60 seconds. Edited by TomoHawk

    If it's not showing correct time more than twice a day it's dead. Seriously, you can open it up and give it a cleaning and lubrication. That brings most of these back to life. There are posts about this subject. Search.

    Sorry, that is wrong. Take it from a watchmaker clockmaker that has been in the business for over 20 years. The majority of quartz clocks in automobiles will tick at one second intervals, nothing to do with saving energy as they use less than any other form of power.

    It's time to get your eyesight and hearing checked there Tom. I've NEVER heard of a clock that only clicks every 5, 10, 15 or 20 seconds to save energy. EVER.

    Clocks tick Every Second, and some click a few times per second. Or they don't "Click" at all. My Rolex does not "Click" at all. It's just one smooth movement. If it starts to click, I want my Money back.

    When I was restoring my instruments and the dash, I had my Z clock repaired by ZClocks (http://zclocks.com/). Some might consider them a little pricey $110, but I did not want to have a hack job going back into my ride or have to worry about it any further.

    The repaired clock works like a champ.

    Actually, it just looks smooth. Your Rolex (like most other Swiss-made mechanical movements) ticks at 8 times per second. Most Japanese mechanicals tick at 6 beats per second.

    I know, I was just making a point. It looks like a smooth movement though. And besides, IT'S A ROLEX!!! I'm just happy to have had it handed down from Grandfather before he passed on.

    Well, I'm off to go hang a 52" flat screen TV for a friend. Yeah for me.... not.

    That is as they are today. From about 1885 to the late 1950's most watches, Swiss and American, had 18,00O BPH, or 5 per second.

    Dave, take care of it, a very fine time peice. The 5 points of the Rolex Crown represent the five fingers of the craftsman that made it.

    Here are 2 examples of what I enjoyed working on. Not Z related, but I couldn't resist. :D

    So you guys are implying that my functional clock is broken because it only clicks every 15 seconds? The same with the clock in my mom's new Lincoln? my alarm clock I've used for the last 20 years only clicks every five (5) seconds, and it's got a quartz thing.

    Tomohawk. You're at it again. Let them deal with the subject of the thread which is testing. If you really want to argue about how they work, start you own thread.

    Nope, we're saying that your hearing needs testing, especially If the clock in the lincoln only clicks every 5 seconds. If every one is arguing against you, you might just be wrong for once.

    Back to the subject at hand.

    Thanks for all of the replies and entertaining banter. :o) I believe I have purchased a clock that doesn't work and am attempting to secure a refund. You guys are a wealth of information and I appreciate your help.
