10. Press 8 to choose Save + Quit (even if item
no. 8 is not visible on the display, it is active
when you select it).
11. Press
Enter to confirm yes you want to save
modifications
to the MPEM.
12. You must see
Operation successful . This
confirms that the new timing has been stored
in the MPEM.
13. Unplug communication cable from safety lan-
yard switch on craft.
14. .Press
Off to close the programmer.
At this point, you can install the watercraft safety
lanyard and start the engine to check the effect of
the correction on the ignition timing. If further ad-
justment is required, repeat the procedure.
NOTE : The MPEM module features a per-
manent (non-volatile) memory and keeps
the ignition timing programmed even when the
watercraft battery is disconnected.
BOMBARDIER IGNITION TESTER
Use of Bombardier Ignition tester
This tester (P / N 295 000 008) can verify generat-
ing coil and ignition coil / CDI module of the igni-
tion system.
Always make sure that tester batteries are in
good condition.
Test Condition
All tests are performed on watercraft at cranking
speed with spark plugs installed.
Always proceed in the following order :
1. Connect tester P and N clip leads as indicated
for each specific test.
2. Follow test procedure sequence.
3. Install cap over safety lanyard switch and crank
engine until light turns on, or otherwise, for a
maximum of 5 seconds.
4. After every test that lights the indicator lamp,
RESET the indicator circuit by depressing the
reset 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
failure, only parts replacement can solve the prob-
lem 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.
