IGNITION SWITCH

NOTE: On the F5/F6, the console must be removed
to access the ignition switch.
1. Remove the harness connectors from the ignition
switch.
2. Rotate the key to the OFF position.
3. The meter must read less than 1 ohm resistance
between the ignition switch terminals.
4. Rotate the key to the RUN position.
5. The meter must read OL (infinite resistance).
Testing Electrical
Resistances (570 cc)

NOTE: Resistance tests of the engine electrical
components should be made using the Fluke Multim-
eter only. Analog-style multitesters may not be accu-
rate enough to use in these critical tests. Replace any
component that does not have a test value within
specifications.
CHARGE COIL (1)
1. Disconnect the four-wire plug from the main harness
to the magneto.
2. Set the selector in the OHMS position.
3. Connect the red meter lead to the brown/white wire
in the plug; then connect the black meter lead to the
green/red wire in the plug.
4. Charge coil (1) resistance must be 12-18 ohms.
CHARGE COIL (2)
1. Disconnect the four-wire plug from the main harness
to the magneto.
2. Set the selector in the OHMS position.
3. Connect the red meter lead to the black/red wire in
the plug; then connect the black meter lead to the
green/red wire in the plug.
4. Charge coil (2) resistance must be 12-18 ohms.
IGNITION TIMING SENSOR
1. Disconnect the green/white and brown/green wires
from the sensor to the main harness.
2. Set the selector in the OHMS position.
3. Connect the red tester lead to the green/white wire;
then connect the black tester lead to the brown/green
wire.
4. Sensor resistance must 148-222 ohms.
LIGHTING COIL
1. Disconnect the main harness from the lighting coil
four-wire connector.
2. Set the selector in the OHMS position.
3. Connect the two meter leads to each of the yellow
leads in the connector from the engine.
4. Lighting coil resistance must be 0.12-0.18 ohm.
IGNITION COIL (Primary)
1. Disconnect the double wire plug from the CDI unit
to the ignition coil.
2. Set the selector in the OHMS position.
3. Connect the red meter lead to the orange wire in the
plug; then connect the black meter lead to the black/
white wire in the plug.
4. Ignition coil primary resistance must be between
0.26-0.35 ohm.
IGNITION COIL (Secondary)
1. Remove the spark-plug caps from the high tension
wires.
2. Set the selector in the OHMS position.
3. Connect the red meter lead to one high tension wire;
then connect the black meter lead to the other high
tension wire.
4. Ignition coil secondary resistance must be between
6800-10,200 ohms.
SPARK-PLUG CAP
1. Remove the spark-plug caps from the high tension
wires.
2. Set the selector in the OHMS position.
3. In turn on each cap, touch a tester lead to each end of
the spark-plug cap.
4. Spark-plug cap resistance must be between 4000-
6000 ohms.
IGNITION SWITCH

NOTE: The console must be removed for this proce-
dure.
1. Remove the main wiring harness connectors from
the ignition switch.
2. Rotate the key to the OFF position.
3. The meter must read less than 1 ohm resistance
between the ignition switch terminals.
4. Rotate the key to the RUN position.
5. The meter must read OL (infinite resistance).
