Diagnosing Distributor - No Spark Chase

Below, distributor "one wire" test. I have removed the other distributor wire for simplicity. Take the bare connector end or this clip lead (the yellow) and with everything hooked up, ground it repeatedly. Each grounding should result in a spark (In this photo you need to hook up the ECU ground wire, I left it off for the photo)


So I finally got around to trying this out. I don't get any spark, but I do get an electrical buzzing of sorts that sounds like its coming from the coil every time I ground it out. It is more of a constant buzzing if i leave it grounded. What is this telling me? Its car week out here in montery and everyone else is driving their cool cars around town I feel left out.
