no spark

["Andy Webster" <trunkie@hotmail.com>]

greetings,
I was playing with my ignition timing yesterday, and after I checked the 
point gap, I could not get a spark.
Can't seem to find where the problem lies.
*points are opening and closing ok
*suspected bad HT lead(s) so put my spare diz cap & leads on..no spark
*can't see any bad/disconnected wires
*have a brand new bosch su120t coil (fancy black transformer type)
Can a condenser just 'die' and would that result in no spark?
Ideas anyone?
Andy
