Generator coil test (HI and LO)
This test is performed on the vehicle at cranking speed .
The two generator coils are called high and low speed
generator coils. The checker indicates the output of
these coils by switching HI and LO positions as follows .
HI: Output of high speed generator coil
LO: Output of high and low speed generator coil
Analysis of this test is diagnosed by its level.
Control unit test
The COl checker inputs alternative current into the con -
trol unit instead of the generator coil.
The output of the control unit will be indicated on the
LED level indicator. Analysis of this test is diagnosed by
its level.
Control unit diode test (for 4-5P ignition
type, 277, 377, 503 engine type)
The control unit includes the diode which controls the
output of the generator co il according to the engine
speed. This checker can diagnose this diode. The result
will be indicated on the LED level indicator.
Spark test
Using an ignition coil equipped on the vehicle, this tester
can cause the spark across the high-tension wire and
engine body
O NOTE: This checker cannot check the following
Items.
- Lighting coil output
- Control unit diode of 4-4P ignition type (354,
454, 464 engine type) .
O NOTE: For lighting coil test, refer to the Bombar-
dier Ignition tester procedure.
BEFORE TESTING
To prevent engine from starting and erroneous indica -
tion on the LED level indicator, remove the spark plug(s) .
_ CAUTION: To prevent dust or foreigh matter from
. " being introduced inside the cylinder(s) when crank-
ing the engine install a clean rag over the cylinder head.
Connect the power cord to the power source (115 volts
AC/60Hz).
_ CAUTION: To prevent any damage to the checker,
. . do not try other power source than the above men-
tioned one and ensure that the checker is installed on a
plane surface, away from vehicle vibrations.
