TROUBLESHOOTING AND ELECTRICAL
SYSTEM: GASOLINE VEHICLES
TEST PROCEDURE 20 – Voltage Regulator
See General Warnings, Section 1, Page 1-2.
NOTE:
Keep the battery connected during this test procedure.
1.
Disable the vehicle.
See Disabling the Vehicle on page 1-3.
2.
Ensure that the wires are connected correctly and are tight. If they are not, rewire or tighten as necessary.
3.
Check the engine RPM setting to ensure that it is adjusted correctly.
See Engine RPM Adjustment on page
4.
With the battery in good condition and fully charged, run the engine for several minutes to bring the voltage
regulator to operating temperature.
5.
Set the multimeter for 20 VDC.
6.
With the engine running at full-governed RPM, measure the battery voltage at the battery posts. If the reading is
between 14.0 and 15.0 volts, the regulator is good. If the reading is lower than 14.0 volts but rising steadily, check
the battery condition.
See Test Procedure 1 – Battery on page 11-8.
7.
If the reading is less than 14.0 volts and not rising, check the charge coil.
See Test Procedure 19 – Charge
Also check for a loose connection at the voltage regulator 3-pin connector and check the
continuity of each wire in the voltage regulator 3-pin connector.
8.
If the reading is more than 15.0 volts and continues to rise, replace voltage regulator.
TEST PROCEDURE 21 – Ignition Spark
See General Warnings, Section 1, Page 1-2.
NOTE:
Keep the battery connected during this test procedure.
1.
Disable the vehicle.
See Disabling the Vehicle on page 1-3.
2.
Remove the spark plug wire from one of the spark plugs.
3.
Use an ignition spark gap test tool (Thexton 404 or equivalent) to check for correct spark.
4.
Adjust tester probes to approximately 18,000 volts (18 kV), setting (SE – Small Engine Setting on the Thexton
404 tool). Connect tester to spark plug wire and connect alligator clip to a solid engine ground.
5.
If there is a strong blue spark between the probes of the spark gap tester, stop the engine and perform the
test on the remaining spark plug.
6.
There should be a strong blue spark between the probes of the spark gap tester when both spark plug circuits are
tested. If there is no spark on either of the ignition circuits, or if either of the sparks is a faint yellow or red color,
test the ignition circuit components.
See the Kawasaki FH680D engine manual (CC P/N 103351201).
7.
If the spark gap tester tool indicates a strong blue spark, it is possible the spark plug has failed internally. Install
a new spark plug set to the proper gap setting and test the engine for proper operation.
TEST PROCEDURE 22 – Engine Kill Wire
See General Warnings, Section 1, Page 1-2.
1.
Disconnect battery and spark plug wire(s).
See Disconnecting the Battery – Gasoline/Diesel Vehicles on
2.
Disconnect the six wire engine harness connector located near the starter
