Minimum values should read:
2500 R.P.M. - 24.0 Volts A.C.
3000 R.P.M. - 29.0 Volts A.C.
3300 R.P.M. - 32.0 Volts A.C.
3600 R.P.M. - 35.0 Volts A.C.
If less than above output, generating coil assembly
is defective.
NOTE: If there is no regulator in this system. The
total output of the two diodes is three (3)
AMPS. If the battery is overcharging (boiling
and bubbling), reduce the D.C. input by
one-half by removing one of the diodes.

This unit combines a 3 Amp D.C. system used to
charge a battery and a 5 Amp A.C. system used for
lighting. Located in the red wire of the harness is a
diode which converts the alternating current to
direct current for charging the battery. The yellow
wire provides the A.C. voltage for the lighting circuit.
A wire harness (part# 36588) may be added to the
3 Amp D.C./5 Amp A.C. charging system to power
an electric clutch without the use of a battery. Test
the diode in the harness by doing a continuity test
(diag. 77).
Replace the diode if continuity exists after reversing
tester leads or if no continuity is found.
CHECKING THE SYSTEM: To check the system,
disconnect the plug and measure the D.C. voltage
at the red wire terminal (diag. 75). Measure the A.C.
voltage at the yellow wire terminal. With the engine
running the minimum values should be:

5 AMP A.C.
3 AMP D.C.
