Condensor/coil problems

Hi all

What am I missing?

The condenser and or coil have repeatedly failed on my '60 Giulietta and '64 Giulia.

On the 'etta twice and the Giulia 3 times; all systems the same misfiring/non start and replacement of the condenser/coil combination cures issues.But, some months and a few miles later same problem.

The replacement condenser/coil initially new replacements but recent replacement NOS, same issues....

Can anyone explain what is going on? Never in 50 years had this and now different cars....exasperated!

Thanks Richard

Condensors have a limited life, even when they are on the shelf, and the poor quality of aftermarket condensors has been discussed on the ABB. That is one of the reasons that many people have switched to a solid state pickup or electronic distributor.

Ed is 100% on this. It's odd that the OLD Bosch condensers as used on Alfa Bosch distributors have more life left in them than the new aftermarket condensers. One on my Ausca single plug 1600 race engine with a Bosch JF-4 is 50+ years old and still just fine! The same is true for the Marelli condensers used on both V12 Ferrari distributors and old original Marelli GTA distributors. Those just last and last. YES, some do fail, but not nearly as often as the new ones.
This has just been my experience.

There is more than one way of constructing condensers and some lead to longer life. The big problem is that they are no longer produced in volume and production runs are short. Anyone who has worked in manufacturing knows that bad product is most often during startup, before the process has stabilized and short runs have a higher proportion of marginal product. The other problem is that the condensers do not have to meet the quality control requirements of automobile manufacturers. That is a problem with many aftermarket parts.
