    hyundai amica primary wave form Archived Message

    X reg amica with distributor and single dry coil ,intermitant cutting out,and my gut feeling straight away leads me to feel its the coil as it cuts under load on road test.Fit a test coil and problem has not returned yet?,but on scoping current ramping looks ok ,but i notice on the primary voltage pattern the dwell period after coil switch on, 2/3rds along, it ramps up by 3 volts till the ping line,and also the spark duration line is a bit eratic,could this be a indication of a fault in the amplifier. I am a relative scope novice and would be grateful for some advice as none of the pretty pictures in my wave form book seem to show this slight ramp in the dwell line.GEORGE ps, figuring out how to post a waveform is on my to do list!
