through the diodes located internally at these points.
D. With the (-) negative lead still connected to point #4, touch point #5. The needle should not deflect.
E. Place the
(+)
positive lead on point #1 and the (-) negative lead on point #3. The Ohmmeter again
should not register any deflection (no deflection indicated infinite resistance). Reverse these connec-
tions and the Ohmmeter should again register no deflection. IF THE RECTIFIER FAILS ANY OF THE
PREVIOUS TESTS (A - E), REPLACE THE RECTIFIER BECAUSE IT IS DEFECTIVE.
4. Integral Controller (I.C.)
The integral controller (I.C.) is an encapsulated, solid-state unit that supplies a DC charging voltage to the
generator's starting battery while the generator is operating.
Charging Voltage:
Charging Amperage:
13.0 - 14.0 Volts DC
0-10AmpsDC
A separate group of stator windings supplies AC voltage to a bridge rectifier which converts the AC current
into DC current to supply the I.C. unit. The I.C. unit senses the needs of the starting battery and supplies a
DC charge when one is needed. If you suspect that the I.C. unit is faulty (that is, if the battery's charge is
low), check the charging circuit's components and performance by following steps #1 - 3. Check all con-
nections for cleanliness and tightness including the ground before replacing the I.C. unit.
NOTE: When the generator is first started, the I.C. unit will produce a low charging rate. This
charging rate will rise as the generator is operated for awhile.
