Test Condition
All Tests are Performed on the Vehicle at
Cranking Speed
Vigorous manual cranking against compression
causes the flywheel to snap over, raising the out-
put higher than by cranking without compression,
therefore, do not remove spark plug.
Test Values Listed are Taken Against
Compression
Always crank vigorously as in actual starting.
Always proceed in the following order:
1. Connect tester P and N clip leads as illustrated
for each specific test.
2. Follow test procedure sequence.
3. After every test that lights the indicator lamp,
reset the indicator circuit by depressing the re-
set button.
Analysis of Test Results
Indicator Lamp Lights at Specific Setting
Output is as specified. Test results should repeat
3 times. If readings do not repeat, output is erratic
and cause should be investigated (loose connec-
tions or components etc.).
Indicator Lamp Lights at Lower Setting
This indicates that the output is less than that de-
signed to operate in a satisfactory manner. How-
ever, before coming to the conclusion of a faulty
condition, be certain that correct engine cranking
conditions were met before condemning the test-
ed part.
Indicator Lamp Does Not Light
One component is defective. Proceed as instruct-
ed to find defective component.
Intermittent Ignition Problems
In dealing with intermittent problems there is no
easy diagnosis. For example, problems that occur
only at normal engine operating temperature have
to be tested under similar conditions.
In most cases of temperature and/or vibration fail-
ure, only parts replacement can solve the problem
as most of these failures return to normal when
engine is not running.
Multiple Problems
There is always the possibility of more than one
faulty part. If after a component has been re-
placed, the problem still persists, carefully repeat
the complete test procedure to find the other
faulty part.
