Default Clock ???

I just got a spare clock from Ebay...I figured before I break mine, I'll practice on this one. I took apart & back together the first time & it works fine with a 9v battery. The only problem is that it's a little fast, not much...I'm glad it's working at all...but is there an adjustment for this?

I don't think there is.

I know a guy who rebuilds clocks and gauges for vettes. If you want his info, let me know.

Mine works when it wants to. Sometimes, it cruises. Other times, it crawls. Most of the time, it just sits there.

I think the best move, is to pick up a quartz conversion kit...

I don't think it's too hard to do.

No one can EVER convince me those clocks ever worked. I think they just needed to cut an extra hole in the panel to make it all look right and they filled it with a *crock*. :cheers:

I believe the original electro-mechanical clocks had a built in provision for adjustment. Once you have the clock running you just adjust the time as needed and the clock will adjust itself to run slower or faster. You may have to do this for a while before it keeps good time. i put a quartz conversion in mine and it's kept perfect time for the past 3 or 4 years with no hassel.

I didn't want to go for the $60 for the converstion yet. I cleaned it & oiled it. Like I said it works fine, just a little fast. I'll look for an adjustment this weekend...

The quartz conversion is really the best option, even though its a little pricy. I had read at one time that the old style clocks worked by a set of contacts opening and closing (much like breaker points in a distributor). If you disconnected the battery, or lost power when the points were in contact with each other you stood a chance of them welding themselves together and the clock is toast. This may explain why so many of the old clocks rarely work.

Your right, I used compressed air first, then cleaned the contact points, then oiled. It works, but your right it could stop if the battery gets disconnected. But I'll give it the old college try first & see how long it goes, I just like to adjust it a little bit...

The owners manual says it will adjust itself for speed when you reset more than 5 minutes ahead or backwards.

I started with a rebuild kit. Went together; worked but determined that the setting shaft's thread was broken so I couldn't set it. I got the whole movemnt (quartz). Wish I would have done that in the first place.

Actually what we have are wind up clocks. The way the clock works is through a spring that is set when the points make contact. The points making contact throws a lever which winds a spring. The clock will run for a while until the spring winds down and then the process repeats itself. The contacts, from years of making contact and sparking, get coroded or stick and won't throw the arm back to wind the spring. That's why the clocks don't work. It's a great idea for saving power because the clock only uses battery power when the points make contact. But in practice it doesn't work so well because of the electrical gremlins that can creep in.

mine will become an air/fuel gage when I put the fuel injection in. Clock is on the CD player and I don't need 2 of them.

Done the quartz conversion. Stops once in a while but I think it's cause the second hand is catching on one of the other hands. :banghead: :leaving:

Mine has said 10 o'clock since I bought it.
I never thought to see if it was just disconnected. I'll have to pull the dash out some weekend and take a peek.

Very seldom will it be disconnected, 99% of the time the old windup system has failed. Mine had a burnt (open) actuator circuit.

Winding the clock CCW seems to work. I also read it the manual...Thanks for the tip.

BINGO! :iagree:

That's what my owners manual says. My clock wouldn't keep running...I unplugged it, then plugged it back in and it ran for like a couple of hours then stopped. After several days like that I got the rebuild kit. I chose the Quart, but with electric movement like the original. You can not tell the difference between the original clock and the one I installed...at least this choice was one of the choices that I really am satisfied with.
