The
various troubles encountered in the engine due to faults in the ignition system
are mentioned below. Of course, it must be kept in mind that the troubles
mentioned are not caused only because of the defects in the ignition systems
that have been mentioned here. Defects in other engine components may also be
the source of the troubles.
Engine missing
There is only one cylinder that is missing, the spark plug is
defective which may be taken out and serviced or replaced as required.
A defective distributor cap or the high-tension lead may be
another reason for this trouble. Replacement of the defective part is the only
solution available.
If many cylinders are missing irregularly, the
ignition timing may be wrongly set, which should be tested and reset.
A defective condenser or coil may be tested separately. If the defect is established, the component should be replaced by a new one of the same
specifications.
The contact breaker points may be worn out or out of
adjustment. They may be cleaned and inspected. Consequently, they are properly
set or replaced if found beyond adjustment.
The spark plugs may be fouled or otherwise defective which
may be cleaned and their gap properly set or even replaced if necessary.
Starting trouble
If the engine does not start at all proceed as follows to locate
the source of trouble.
The battery may be discharged or the battery connections may
be loose or the battery leads may be broken or disconnected. A quick check is
to switch on the headlamps. If this light with adequate brilliance, it is sure
there is no trouble on account of the battery.
Check whether all the external connections are tightly
secured.
Engine making noise
when accelerating
The possible reasons in this case also may be the use of a plug
hotter than that specified and too much retarded ignition timing.
Engine overheating
Too much retarded ignition time may be the cause of this
trouble, which should be checked and reset correctly.
Engine backfiring
The spark plugs used may not be in the correct heat range. The
only remedy is to replace the same with new plugs of suitable range.
The ignition timing may be too much retarded, which should be
checked and reset.
