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-
a
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
and b.
8. Disconnect the lighting coil couplers c

service tools a and b.
9. Repeat steps 4 and 5.
10. Remove the intake manifold (STBD).
11. Disconnect the special service tools a
and b.
12. Measure the lighting coil resistance.
