New clock not working

[ZwolleY]

Got a new used clock which I presume is working well under normal conditions. Got it plugged in, set the time and waited a few minutes. The hands didn't move. Checked the fuse box and found a blown fuse-10 amp for dome light and instruments. Replaced it and the dome light still does not work (could be unrelated but it did work) but the instrument lights do. Clock did not work with the new fuse. Is there another fuse somewhere that I should check? I am certain I have the correct wires connected allthough I erred by not marking them. There are two wires comming from the harness that connect with the blue and black wires on the clock-one blue and one black, both are shielded with a black rubber protecter. I connected these. There was also another black wire of the same size with plug in connections near the clock which were unconnected and I reconnected these. My guess this is for something else.

Worst case scenerio is that when the fuse blew, it blew the clock:sick:

How sure are you that the clock was functional when you bought / got it?

Never assume!

Have you tried to test the clock with an alternate power source? I'd start there.

I think I have been through this before. I got the clock off of eBay from an outfit that sells other Z stuff. It has a 30 day warrantee. When I contacted them they said that it had been tested and observed for two weeks and that it ran fine. Let the buyer beware I guess.

So how do I hook it up to an alternate power source? Can it be alligator clipped to a 6 volt battery, or 12 volt?

You can alligator clip it directly to the battery 12v.

just a little tale on the side....

My clock doesn't work either. BUT when I pulled it apart & just had the motor plugged in to 12V it worked fine. Put it back together, no-go.

This fault drove me to replacing it with a boost gauge....:classic:

Hey Ben. I visited Australia for about 9 months in 1965 and had a very good time traveling from Sydney to Melbourne back to Sydney then north to Cairns. Worked for three months west of Cairns on a road construction job near Mt. Surprise. Then to Darwin where I hitched a ride on a yacht westward. Well, back to the Z. You said that you hooked your clock up to a "boost guage". What is that?

The clock runs off a 12 volt battery and will retry it on the car wiring tomorrow. Thanks for your help.

ZwolleY: Ben said that he "replaced" the clock with a boost guage. A Boost guage shows the amount of "boost" (added air pressure) a Turbocharger is pumping into an engine to make horsepower. :classic:

If the clock works outside of the car, next step is to check the wiring in the car to make sure that A. there is power to the clock. and B. that the ground wire that plugs into the clock actually is connected to a good ground. Once those two things have been confirmed, the clock SHOULD work in the car. Although, from what Ben experienced I guess that's not always the case.

Good Luck and let us know what you find.

If you got the refurbished or reworked clocks from the guy on E-Bay with Zclocks or something like that as his e-mail, he's pretty reliable and trustworthy. More than likely you may have hooked into the wrong power connectors or you're not getting power to the clock.

Right by that area of the wiring harness, where the clock plugs in, there is another power connector that goes to the glove box light. Since they're both interconnected no problem. The power to the glove box light and the clock is also the same power that goes to the dome lamp and courtesy lamp circuit, so if you have a dome lamp, you should have power.

The clock has a small electric motor that just tightens a coil spring. The coil spring is what actually drives the clock mechanism. As the coil unwinds, the motor kicks in and tightens it up again.

To check that you have the right connectors for the clock, look for the light bulb socket that goes to the clock, the black and blue wires come one each from the two trunks of the wire harness right next to the lead for the light bulb socket wire. If they're not right next to that wire, then you're looking at the Red/Blue wire for the glove box light. The blue wire has a Female bullet connector and the black has a Male bullet connector, the clock should have the proper gender on the respective wires.

Plug the clock in, worst case scenario, give it a little thump up side the head, you should hear the motor whirr and the clock start ticking. If this still doesn't do it, give me an e-mail, I'm just down the road from you and I could scoot on up there and give you a hand.
