[AT] Well, I guess I didn't really want it to be easy

[Richard Strobel]

Concur with Dean...so many factor's, i.e. humidity, manufacturer, 
environment surrounding the condenser whether it be mag. or distributor. 
Ohm meter can give a false reading..known good one or new one is the only 
way to tell.

  Best Regards;
  RickinverydryMt.
