3. Connect the test harness (1 pin) 1 to
any stator coil coupler.
4. Measure the stator coil output peak volt-
age. Replace the stator coil if below
specification.

NOTE:
Select any 2 of the 3 couplers (leads) and
measure the output peak voltage between
the selected couplers. Then, measure the
output voltage between the coupler that was
not measured and any coupler.

5. Measure the stator coil resistance.
NOTE:
Select any 2 of the 3 couplers (leads) and
measure the resistance between the selected
couplers. Then, measure the resistance
between the coupler that was not measured
and any coupler.

Checking the Rectifier Regulator

CAUTION:
If the battery cables are connected in
reverse, the Rectifier Regulator can be
damaged.
1. Remove the starboard intake manifold.
2. Remove the fuse holder and disconnect
the Rectifier Regulator coupler 1, and
then install the starboard intake manifold.
NOTE:
• When installing the starboard intake mani-
fold at this time, be sure to leave the Recti-
fier Regulator coupler on the outside of the
manifold.
• To install the starboard intake manifold, see
Chapter 4, "Installing the intake manifold."
3. Measure the Rectifier Regulator output
peak voltage. If below specification, mea-
sure the stator coil output peak voltage.
Check the Rectifier Regulator if the out-
put peak voltage of the stator coil is
above specification.
