TROUBLESHOOTING

Ignition Problems
When dealing with ignition problems, the follow-
ing items should be checked in this order. After
one item has been checked and it is found not to
be the problem, continue with the next item:
130
1. fuse
2. spark plug (spark occurence)
3. battery
4. ignition switch
5. engine stop switch
6. trigger coil
7. ignition coil
8. ignition module
9. shift gear control module.
Intermittent Ignition Problems
In dealing with intermittent problems there is no
easy diagnosis. For example, problems that occur
only at cold engine temperature have to be tested
under similar conditions.
In most cases of temperature and/or vibration fail-
ure, only parts replacement might 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.

REPAIR PROCEDURES

Safety Precautions
WARNING
To prevent powerful electric shocks while
cranking engine, neither touch any electronic
ignition components (ignition coil, wire har-
ness, etc.) nor tester lead clips. Also make
sure that tester leads do not touch any metal-
lic object.
For best electrical measurement results, use the
multimeter Fluke 111 (P/N 529 035 868).
