Disconnect the ignition pulse generator wire connector
(Blue/yellow) (1].
Connect the peak voltage tester
or
adaptor probes
to
the ignition pulse generator wire connector and body
ground.
In
the same manner
as
at the ICM connector, measure
the peak voltage and compare it to
the
voltage
measured at
the
leM
connector.
If the peak voltage measured
at
the
leM
is abnonnal
and the one measured at the ignition pulse
generator is normal, the wire harness has
an
open
or short circuit,
or
loose connection.
If bolh peak voltages are abnormal, follow the
._
checks described
in
the troubleshooting chart
(page
4-4).
Refer to procedure for alternator stator replacement
(page 11-5).
IGNITION TIMING
Warm up the engine.
Stop the engine and remove the timing hole cap from
the left crankcase cover.
Read the Connect a liming light [1]10 Ihe spark plug wire.
instructions for
timing light
operation
.
Start Ihe engine and let it idle.
IDLE SPEED: 1,400
± 100 rpm
The ignilion timing
is
correct if the "F" mark [2]
on
Ihe
flywheel aligns with the index notch (3]
on
the left
crankcase cover.
Coat a new O-ring
[1]
with engine oil and install it onlo
the timing hole cap [2].
Install the timing hole cap and tighten it to the specified
torque.
