Connecting the Secondary Coil Adapter Leads:
1.
Connect the black (ground) lead into the diagnostic tool test lead ground jack.
2.
Connect the yellow lead into the diagnostic tool test lead channel 1 jack.
3.
Connect the adapter lead ground clamp to vehicle ground. If a jumper wire is
used to extend the length of the adapter lead ground clamp lead, keep it as
short as possible.
4.
Connect the adapter lead RCA plug into the secondary ignition "clip-on" or
COP/CIC coil adapter as needed.
5.
Clamp the secondary clip-on adapter over a spark plug or coil lead, or attach
the applicable COP/CIC coil adapter to the vehicle ignition coil.
6.
Isolate the leads from other components, to avoid any unwanted noise that
could be induced onto the signal.
7.
From the lab scope function, select the Ignition Probe (probe setting).
8.
If needed, turn the Invert function on.
Once a signal is displayed, further channel settings may be required to display the
pattern characteristics you a looking for.
