Vegolia clock repaired for $20

Great job. I wish I were competent in the electronics field. My clock repair cost me a little over $100 US and I did not have the satisfaction of doing it myself.

 

Nice find!

Nice work! Any thoughts on whether this is applicable to the 328's Veglia clock, and how different the 308 vs. 328's components might be?

 

Great detective work on the problem part search.

 

The 328 does have the same chip. Just took mine apart.

How did you determine that the IC was bad? Was it simple a process of elimination? Never tested circuit board components before so I am learning as I go. Any help would be greatly appreciated. Thanks.

 

Hi Wade,

If you have not seen it, you may want to have a look at this thread:

Not sure how much is applicable for the 328... If you have a look at the various pictures you should be able to figure this out. The clock I found to repair the one in my '84 308 QV was for a Fiat 124 and it was basically identical mechanically. The board was similar in design (but not exactly the same) and certainly did the trick.

Once I determined that it was a board level (or motor) failure I did some diagnostics, but ultimately decided that it would be far easier to switch the hands/faces/'color ring' out and simply replace the entire mechanism with the functional one. (I might mention here that I have an advanced degree in Electronics and Electrical Engineering, so am not a stranger to board level work).

My suggestion would be to keep an eye out for a similar Veglia clock (look at the other thread for more details on what to look for) and tackle it that way.

All this being said, there is nothing at all wrong with replacing the IC just as long as you are sufficiently confident of your soldering skills as replacing it is not straightforward, I.e., the motor actually couples the board to the plastic mechanism (with all the gears) beneath such that you would need to separate that: This means removing the solder from the motor contacts or breaking the plastic where the motor mounts.

Either way, hope this input helps and good luck!

John.

 

Thanks for the this. I think I am going to have it professionally fixed or try to find a replacement. I will search the site for options.

Wade,

I called around and got one quote of ~$450 plus shipping to replace the mechanism (with a different VDO movement) in mine (this was for a 308)... If you aren't in a hurry, it is worth having a go at doing this yourself. I am not familiar with the 328 clock, but under the assumption that it is basically the same mechanism as the 308, Fiat, etc. all you would need to do is to swap the bits over (face, hands, etc.) from your original.

Best,

John.

 

At that price, patience truly is a virtue! I will look around. Thanks for the heads up John.

Saw this...

Looks to be a candidate for swapping out the hands, etc. on your original... If you are not bothered about cosmetics, then you could likely just use it as is.

Best,

John.

 

G'day Glen,

Agreed that running the clock 24/7 for over 30 years is going to be quite a test for the IC (albeit with small current). These were my thoughts initially as well...

Going the IC replacement route, what was your approach in separating the PCB from the plastic part that holds the gears? Did you de-solder the contacts on the clock to free it?

Just curious here...

Also, was the 350 ohms measured across the clock terminals when it was isolated from the rest of the circuit?

By the way, good work on sourcing the replacement IC! I may get a couple in case I need them in the future...

Best,

John.

 

Lawrence...where did you have your clock fixed?

 

Hi Glen,

Thank you for the input...

Just to follow up, I had another look at my defective board and testing across the clock terminals yielded 'open' (i.e., infinite resistance). I guess the lesson learned here is that a quick check of resistance across these contacts will point you in the direction of the failed component.

Thanks again.

John.
