When the plugs have been carefully cleaned,
examine the central insulators for cracking and
the centre electrode for excessive wear. In
such cases the plugs have completed their
useful life and new ones should be fitted.
Finally,
before re-fitting the sparking plugs the
electrodes should be adjusted to the correct
gap setting of ,020 in, (.5mm.). Before refitting
sparking plugs
the threads should be cleaned
by means of a wire brush an a minute amount
of graphite grease smeared onto the threads.
This will prevent any possibilitY of threads
seizure occurring.
If the ignition timing and carburation settings
are correct and the plugs have been correctly
fitted,
but over-heating still occu rs then it is
possible
that carburation is being adversely
affected by an eir leak between the
carburetter, manifold and the cylinder heec!.
This possibility
must be checked thoroughly
before taking
any further action. When it is
certain that none of the above mentioned
faults are the cause of over-heating then the
plug type and grade should be considered.
Normally the type of plugs quoted in "General
Data" are satisfactory for general use of the
machine but in special isolated cases,
conditions may demand a plug of a different
heat range. Advice is readily available to solve
these problems from the plug manufacturer
who should be consulted.
Note- if the air filter has been removed it will
affect
the carburation of the machine and
hence may adversely affect the grade of
sparking plugs fitted.
SECTION H5
CHARGING SYSTEM
DESCRIPTION
The charging current is supplied by the two
lead alternator, but due to the characteristics
of alternating current the battery cannot be
charged direct from the alternator. To convert
the alternating current to direct current a full
wave bridge silicon type rectifier is connected
into the circuit. The alternator gives full output,
all the alternator coils being permanently
connected across the rectifier.
Excessive
charge is absorbed by the Zener
Diode which is connected across the battery.
ALTERNATOR
Always ensure that the ignition switch is in the
"OFF" position whilst the machine is not in
use, to prevent overheating of the ignition
coils, and discharging
the battery.
To locate a fault in the charging circuit, first
test the alternator as described in H5 Part B. If
the alternator is satisfactory, the fault must lie
in the charging circuit, hence the rectifier must
be checked as given in Section H5 Part C
(page H
10) and then the wiring and connec-
tions as shown in Section H5 Part 0 (page
H 121.
