<VV> Starter Mystery-Continued/Solved?

[Bill Elliott]

If the Ignitor was trying to run on such a reduced voltage, that's likely 
the cause of death. Outside of the abuse cases (where someone left the key 
on with the engine off) and racing use, nearly 100% of the known Ignitor I 
failures are with modules hooked directly to the coil rather than to a 12V 
source as specified by Pertronix.

(Even though the Ignitor II is protected against either of these sorts of 
death, it really made a performance difference when I changed from ballasted 
voltage to 12V in the Corvair Westy)

Cranking an Ignitor with the primary wire disconnected can also kill an 
Ignitor (and possibly a coil as well... killed a coil not that long ago 
myself in a BMW doing a compression test without disconnecting the coil 
power)
