Never could find how to tell the difference? But I will check the pinout tomorrow and let you know which ones I am using. One of your settings is probably WRONG !!! Running with Spark Output set wrong can damage your COPs and/or drivers !! From the manual...........
Be sure you have set MS3X spark hardware and for 99% of installs you should set Spark Output to "Going high (inverted)" Note to upgraders
, if you were previously using the "LED drivers" with a pullup to give a logic spark then you were almost certainly set to "Going low (normal)" before, so be sure to switch that setting to "Going high (inverted)" when moving to MS3X spark outputs.
That is from this link. a little over half way down. http://www.msextra.com/doc/ms3/ignition.html#settings
PS here is a link showing the pinouts on 20V dizzy http://www.msextra.com/doc/ms3/trigger-wheel.html#nippon
but I will still have to look at which one I am using.
