A jumper wire is required for this test.
Make sure key switch is OFF before connecting
jumper wire.
NOTE: Mark or identify the charging indicator wire
in the output harness before disconnecting
the harness from the connector.
CAUTION: If the jumper wire contacts the charg-
ing output wire during the test while the key switch
is ON, the wiring harness could be damaged.
1. Disconnect output harness (3) at WHITE con-
nector (4), Fig. 44 .
2. Attach one end of jumper wire (5) to a good
ground.
3. Attach other end of jumper wire (6) to charge
indicator terminal in harness connector, Fig. 44 .
a. Turn key switch to ON position (1).
b. If bulb (2)
LIGHTS , charge indicator wiring
system is OK. Replace regulator/rectifier.
c. If bulb DOES NOT LIGHT , replace bulb.
d. If new bulb does not light, the problem is an
OPEN CIRCUIT (broken wire) in the
charging indicator circuit. Refer to typical
wiring diagram.
•
SYMPTOM: Charge Indicator Light Stays ON –
Engine Running.
NOTE: Indicator light will remain ON if battery volt-
age is
below 12 volts .
4. Check indicator light wiring.
a. If wiring is grounded, light will remain ON
when engine is running.
b. If wiring is OK, replace regulator/rectifier.

Testing Engine Wiring Harness
The engine wiring harness consists of a ground wire
(1) with a diode (4) for each armature (5) and a sepa-
rate wire (2) for the carburetor solenoid,
Fig. 45 . The
engine wiring harness is connected to the wiring har-
ness provided by the equipment manufacturer. A
raised rib on the polarized connector (3) indicates the
ground side.
See engine wiring harness diagram on the next
page.

Ground Wires
Digital Multimeter # 19464 is used for these tests.
In the Diode Test position, the meter will display the
forward voltage drop across the diode(s). If the
voltage drop is
less than 0.7 volts , the meter will
BEEP once and display the voltage drop. A
continuous tone indicates CONTINUITY (shorted
diode). An INCOMPLETE CIRCUIT (open diode)
will be displayed as OL .
1. Insert RED test lead into V receptacle in meter.
2. Insert BLACK test lead into COM receptacle in
meter.
3. Rotate selector to +

)) (DIODE TEST) position.
4. Insert RED test lead clip into connector (1)
(BLACK wire), Fig. 46 . Leave attached for
remainder of test.
5. Touch BLACK test lead probe to terminal (2).
a. If meter BEEPS once, diode is OK.
b. If meter makes a CONTINUOUS TONE ,
diode is shorted. Replace ground harness.
c. If meter displays OL , diode is open. Replace
ground harness.
6. Repeat test for terminal (3). Results must be the
same.
