Checking The Ignition System; Ignition Coil Primary Voltage Check - Honda XLR200R Service Manual

CHECKING THE IGNITION SYSTEM
• If there .are n.o sparks from the
spark
plug, check each
part for loose
.or
poor connections, then measure peak·
voltage.
• Input resistance varies"depending on the type of tester
used', resulting- in incorrect reading
and
measurement.
Use digital tester with input impedance of 10
MQ/DC
V
.or more.
Connect peak
voltage
adaptor to digital tester.

IGNITION COIL PRIMARY VOLTA<;E
• Measure after proper connection of all electrical lines.
Correct reading and measurement can not be achieved
if line$ are not properly connected.
• Since there is cylinder pressure, check with the plug
and cap in normal position. If spark plug is removed and
tested by itself, peak
voltage
tends to be higher.
Le. a ve
the spark plug in the cylinder head, attach good spark
plug to the cap, then ground.to engine.
Remove fuel tank (0:>2-8)
Keeping the cord attached to the ignition coil, attach peak
voltage adapter between the primary cord, terminal and the
body ground.
Connection Method: blacklyellow cord terminal
(+)
to body
ground H
Turn ignition switch ON, and RUN engine stop switch.
Crank tne engine, measure peak voltage.
Peak Voltage: more than 100V
Avoid touching the spark plugs and tester probes to
prevent electric shock.
