To add even more to that: Heck the coil will still fire even if theres NO condensor at all. If the condensor value is too large she may not fire at all,,,,,,,,,If its too small she can still fire but the sparks weaker and the points burn up sooner. Of course, if its shorted theres NO spark
The condensor rating is computed based much on the inductance value of the coil which accunts for the diffrerence in values for different cars trucks n tractors which may have different inductance rated coils.
For sure, diferent values of condensors will still "work" (see above) while its still better if they are at least somewhere near the correct size to correspond with the coils inductance value......
Hope this helps, best wishes n God Bless
Fun chat for us sparkies at least
