INSPECTION
IGNITION COIL PRIMARY PEAK VOLTAGE
• Remove the frame head covers and frame upper covers.
(!VL1500 Service Manual 6-3)
• Remove the cylinder head side caps and disconnect the
spark plug caps. (!VL1500%Service Manual 3-8)
• Connect new spark plugs to each spark plug cap and ground
them to the cylinder head.
NOTE:
Make sure that all couplers and spark plugs are connected prop-
erly and the battery used is in fully-charged condition.
Measure the #1 and #2 ignition coils primary peak voltage in the
following procedure.
• Connect the multi-circuit tester with peak voltage adaptor as
follows.
+ Probe: White terminal
#1 ignition coil:
- Probe: Ground
+ Probe: Black/Yellow terminal
# 2 ignition coil:
- Probe: Ground
NOTE:
Do not disconnect the ignition coil primary wire coupler.
# 09900-25008: Multi-circuit tester set

Before using the multi-circuit tester and peak volt
adaptor, be sure to refer to the appropriate instruction
manual.
• Shift the transmission into neutral and turn ignition switch
"ON".
• Crank the engine a few seconds with the starter motor by
depressing starter button and check the ignition coil primary
peak voltage.
• Repeat the above procedure a few times and measure the
highest ignition coil primary peak voltage. If the peak voltage
is lower than the specified values, inspect the ignition coil.
" Ignition coil primary peak voltage: 180 V and more
*Tester knob indication: Voltage (+)

Avoid touching the tester probes and spark plugs to
prevent an electric shock while testing.
