contact bracket until the specified
airgap is obtained. Secure the
adjustment by tightening the two
screws.
(g)
Push down on the voltage regulator
armature until the voltage regulator
contact point barely touches the
adjusting screw. Measure the
airgap between the coil core and the
armature of the voltage regulator.
Do not measure between the core
residual brass pin and the armature.
The correct voltage regulator airgap
is 0.084 inch.
(h)
Adjust the correct regulator airgap
to 0.115 inch in the same manner
as for the voltage regulator unit
described in g above.

Electrical adjustments. Install set of test
adapters as illustrated on figure 9.
Note.
Refer to C figure 9 and polarize the
generator.
