Ignition System Inspection; Ignition Coil Primary Peak Voltage - Honda 2000 XR50R Service Manual

IGNITION SYSTEM INSPECTION
NOTE:
-If there is no spark at plug, check all connections
for loose or poor contact before measuring each
peak voltage.
• Use recommended digital multimeter or commer-
cia lly available digita l multi meter with an

_If using peak voltag8 tester (U.S.A. only), follow
the manufacturer's instructions. PEAK VOLTAGE ADAPTOR
Connect the peak voltage adaptor to the digital
multi meter, or use the peak voltage tester (U.S.A.
only).
TOOLS:
Peak voltage tester (U.S.A. only) or
Peak voHage adaptor 07HGJ-0020100

IGNITION. COIL PRIMARY PEAK VOL-
TAGE
Avoid touching the spark plug and tester probes
to
prevent electric shock.
NOTE:
• Check all system connections before inspection.
If the system is disconnected, incorrect peak
voltage might be measured.
• Check cylinder compression and check that the
spark plug is installed correctly.
Disconnect the spark plug cap from the spark plug.
Connect a known good spark pl ug to the spark plug
cap and ground the spark plug to the cylinder as
done in a spark test.
GOOD KNOWN SPARK PLUG
