Spark Plug Cap
1. Connect the red tester lead to one end of the cap;
then connect the black tester lead to the other end
of the cap.
AR603D
2. The meter reading must be within specification.
NOTE: If the meter does not read as specified,
replace the spark plug cap.
PEAK VOLTAGE
NOTE: All of the peak voltage tests should be
made using the Fluke Model 77 Multimeter with
Peak Voltage Reading Adapter. If any other type of
tester is used, readings may vary due to internal
circuitry.
NOTE: The battery must be at full charge for
these tests.
Primary/CDI (400 TRV/650)
NOTE: The CDI is located on the electrical tray in
front of the steering shaft.
KC210B
1. Set the meter selector to the DC Voltage position;
then disconnect the black/yellow and black pri-
mary wires (400 TRV) or the terminal and ground
wires (650) from the coil.
2. Connect the red tester lead to the one wire; then
connect the black tester lead to the other wire.
3. Crank the engine over using the electric starter.
4. The meter reading must be within specification.
Primary Voltage - ECU (H1)
1. Set the meter selector to the DC Voltage position;
then disconnect the two wires from the coil.
2. Connect the red tester lead to the orange wire and
the black tester lead to the blue/white wire.
3. Turn the ignition switch to the ON position. The
meter must show battery voltage.
Primary Voltage - ECU (H2)
NOTE: The battery must be at full charge for this
test.
NOTE: The ECU is located beneath the rear body
panel near the taillight.
1. Set the meter selector to the DC Voltage position;
then disconnect the orange primary wire from the
coil.
2. Connect the red tester lead to the orange primary
wire; then connect the black tester lead to ground.
3. Turn the ignition switch to the ON position.
4. The meter reading must be within specification.

(EFI)
CRANKSHAFT POSITION (CKP)
SENSOR
To test the CKP sensor, see Stator Coil/Crankshaft
Position (CKP) Sensor (EFI) in this section.
MANIFOLD ABSOLUTE PRESSURE
(MAP) SENSOR
1. Disconnect the MAP connector from the pressure
sensor located on top of the throttle body.
2. Select DC Voltage on the tester and turn the igni-
tion switch to the ON position.
3. Connect the black tester lead to the black/green
wire and the red tester lead to the orange/blue
wire. The meter should read 4.5-5.5 DC volts. If
the meter does not read as specified, check the
ECU connector or wiring.
4. Connect the MAP to the harness; then using Maxi-
Clips, connect the red tester lead to the
brown/white wire and the black tester lead to the
black/green wire. With the engine running at idle
speed, the meter should read approximately 1.5
DC volts.
NOTE: If the meter does not read as specified,
replace the sensor.
