Hi Al,
 
I have not seen degraded spark from a LS1 coil, since I have only used the LS1 coils on my 20B.  I can say that I have seen degraded performance (output voltage/current) on a single coil ignition system on a GM engine.  I would imaging that in addition to failure of solid state components the primary or secondary winding could have a defect (imtermitent open, short or high resistance) that would affect the output voltage.

Has anyone noticed a “degradation” of spark strength as a failure mode of the LS1 coils?  I’ve assumed that a coil failure would most likely occur due to failure of a solid state component in the coils circuitry; resulting in no spark.
