Dual Circuit Alternator
The dual circuit alter nator provid es DC for
battery charging and AC for the headlights. The
battery is not used for the lights, so lights are
available if battery is disconn ected or removed.
The current from the DC side of the alternator is
unregulated and rated at 3 amps. The output
rises from 2 amps at 2400 RPM to 3 amps at
3600 RPM.
This alternator uses a polarized plug with two
pins. The RED lead (
A ) charges the battery, the
WHITE lead ([ B ] Fig. 26) is for lights.

Dual Circuit Alternator DC Output Test
Test in the following sequence:
1. Set meter. See Figure 11.
2. Attach RED test lea d clip to DC output pin
([ E ] Fig. 27) in the connector ([ F ] Fig. 27).
The bump on the connector indicates the
DC output terminal.
Fig. 27
3. Atta ch BLACK test lead clip to positive (+)
battery terminal.
4. Start engine.
With a fully charged batte ry, ou tput will be
approximately 2 amps DC at 3600 RPM.
If no or low output is found:
• Test the diode.
Dual Circuit Diode Test
1. Rotate selector to +))))) (DIODE TEST)
position. See Fi gure 9.
2. Attach RED test lead clip ( A ) to point ( B )
and BLACK test lead clip ( C ) to DC output
pin ( D ). Fig. 28. (I t may be necessary to
pierce wire with a pin as shown( E )).
If meter beeps once:
• Diode is OK.
If meter makes a continuous tone :
• Diode is shorted.
• Replace the diode.
If meter displays
OL:
• Proceed to step 3.
3. Reverse test leads.
If meter beeps once:
• Diod e is installed backwards.
