I've run thru this thread kinda late,so if these things have been suggested/tried
already forgive me.
1)are you getting a signal out of the pick-up coil?Disconnect the 2 wire at the
dizzy and ohmmeter the dist PU ,if the reading is in spec.,crank the eng.
and you should see a definite rhythmic variation in the reading.Was much
easier to check w/analog sweep meters,but digi's w/a bar graph work ok.
otherwise you just have to watch the numbers change.
