LAUNCH KES-200 Starting System Analysis
E-4
CONNECTION 4:
Connection for secondary ignition
waveform test of 4 cylinders is as shown in Fig.4-09.
This connection method is applied when all
high-tension wires are easily accessible.

The connection to test the primary/secondary
ignition waveform for testing single cylinder
There are three ways (CONNECTION 5, 6, 7):
CONNECTION 5:
The high-tension wire of one plug
is located outside and that of another plug is hidden in
the coil. The primary lead can be found. In this case,
the unit can test the primary and secondary ignition
waveform. The connection is as shown in Fig.4-10.
When such connection is used to test the secondary
ignition waveform, select primary trigger mode to get
the very stable secondary ignition waveform. If the
primary negative lead of the ignition coil can’t be found,
select the secondary trigger mode to get the
secondary ignition waveform. To test the high-tension
ignition signal waveform hidden in the ignition coil, use
the
secondary signal slice sensor
to get the secondary
ignition waveform.

CONNECTION 6
: The high-tension wires of both
spark plugs are exposed. The primary negative lead
of ignition coil is hidden. In this case, just the
secondary ignition waveform can be tested. The
connection is as shown in Fig.4-11. Remember to
select secondary trigger mode to get the secondary
ignition waveform for this connection.
