Peak voltage adapter
NOTE:
Throughout this chapter the part numbers of
the specified peak voltage adapters have
been omitted. Refer to the following part
numbers.
The peak voltage adapter should be used
with a digital tester.
When measuring the peak voltage, connect
the peak voltage adapter to the digital circuit
tester and switch the selector to the DC volt-
age mode.
NOTE:
Make sure that the adapter leads are prop-
erly installed in the digital circuit tester.
Make sure that the positive pin (the “+” mark
facing up as shown) on the adapter is
installed into the positive terminal of the
tester.
The test harness is needed for the following
tests.
È Voltage measurement
É Peak voltage measurement
Test harness
NOTE:
If the lighting coil and pickup coil(s) are mea-
sured unloaded, disconnect the test harness
on the output side coupler.
Peak voltage adapter:
YU-39991
Peak voltage adapter B:
90890-03172
Checking steps:
Disconnect the coupler connections.
Connect the test harness between the
couplers.
Connect the tester terminals to the termi-
nals which are being checked.
Run the engine and observe the mea-
surement.È

IGNITION SPARK
WARNING
When checking the spark gap, do not
touch any of the connections of the spark
checker/ignition tester lead wires.
When performing the spark gap test, take
special care not to let sparks leak out of
the removed spark plug cap.
When performing the spark gap check,
keep flammable gas or liquids away,
since this test can produce sparks.
1. Check:
Ignition spark
Weak →
Check the ECM output peak
voltage.
Check the ignition coil for resistance.
Checking steps:
Connect the spark plug cap to the special
service tool.
Spark checker:
YM-34487
Ignition tester:
90890-06754
Crank the engine and observe the igni-
tion system spark through the discharge
window.

IGNITION SYSTEM PEAK VOLTAGE
WARNING
When checking the electrical components,
do not touch any of the connections of the
digital tester lead wires.
NOTE:
If there is no spark, or the spark is weak,
continue with the ignition system test.
If a good spark is obtained, the problem is
not with the ignition system, but possibly with
the spark plug(s) or another component.
1. Measure:
ECM output peak voltage
Below specification →
Measure the
pickup coil output peak voltage.
NOTE:
When measuring the ECM output peak volt-
age while cranking the engine, disconnect
the ignition coil couplers for all cylinders
except for the cylinder being measured.
To crank the engine, connect the engine
shut-off cord (lanyard) to the engine shut-off
switch, and then press the start switch.

IGNITION COIL
1. Measure:
Primary coil resistance
Out of specification →
Replace.
NOTE:
When measuring a resistance of 10 Ω
or less
using a digital tester, the correct measurement
cannot be obtained because of the tester’s
internal resistance.
Refer to “Low resistance measurement”.
Primary coil resistance:
1.19–1.61
Ω at 20 °C (68 °F)
2. Measure:
Secondary coil resistance
Out of specification →
Replace.
Secondary coil resistance:
8.5–11.5 k
Ω at 20 °C (68 °F)
