Ignition Coil And Plug Cap Inspection - Suzuki Intruder VZ1500 Service Manual

Ignition Coil and Plug Cap Inspection

Refer to "Electrical Components Location in Section 0A
(Page 0A-7)".
Ignition Coil Primary Peak Voltage
Inspect the multi-circuit tester with peak voltage adaptor
as procedures:
1) Connect new spark plug to each spark plug cap and
ground them to the cylinder head.
2) Connect the multi-circuit tester with peak voltage
adaptor as follows:
#1 and #2 ignition coil
(+) probe: W/Bl lead wire (#1 cylinder)
(+) probe: B lead wire (#2 cylinder)
(–) probe: Ground
NOTE
Do not disconnect the ignition coil primary
wire coupler.
Special tool
: 09900–25008 (Multi-circuit tester set)
: 09900–25009 (Needle pointed probe set)
CAUTION
!
Before using the multi-circuit tester and peak
volt adaptor, be sure to refer to the
appropriate instruction manual.

3) Inspect the ignition coil primary peak voltage in the
following procedures:
WARNING
!
Do not touch the tester probes and spark
plugs to prevent an electric shock while
testing.
a) Shift the transmission into neutral, turn the
ignition switch ON and grasp the clutch lever.
b) Press the starter button and allow the engine to
crank for a few seconds, and then measure the
ignition coil primary peak voltage.
4) Repeat the b) procedure several times and measure
the highest peak voltage.
Ignition coil primary peak voltage
150 V and more
If the peak voltage is lower than the specified values,
inspect the ignition coil. Refer to "Ignition Coil and Plug
Cap Inspection (Page 1H-7)".
