4. Install the intake manifold (STBD). Check
that the connector of the special service
tools
a
and
b
are not covered by the
intake manifold (STBD). See “Installing
the intake manifold” (6-16).
5. Measure the lighting coil output peak
voltage between all combinations of the
terminals. Replace the stator assembly if
below specification.
TIP:
When measuring the lighting coil output peak
voltage under the cranking (unloaded) condi-
tion, remove the clip from the engine shut-off
switch to prevent the engine from starting.
6. Remove the intake manifold (STBD).
7. Disconnect the special service tools
a
