Triumph Trident T160 - Checking the High Tension Circuit; Control Breaker Assembly Type 7 CA

ELECTRICAL SYSTEM
H
Particular attention is called to the periodic
lubrication procedure
for the contact breaker
which is given in Section A 11. When lubri-
cating the parts ensure
that no oil or grease
gets
onto the contacts.
If it is felt the contacts require surface grinding
then the complete contact breaker unit should
be removed
as described in Section B24 and
the moving contacts removed by unscrewing
the nut which secures the low tension lead,
removing
the lead and nylon bush. The spring
and
contact point can be removed from ~he
pivot spondle. Repeat this procedure for the
other contact points.
Grinding is best
achieved by using a fine
carborundum stone
or very fine emery cloth,
afterwards wiping away any trace of dirt or
metal dust with a clean petrol (gasoline)
moistened cloth. The
contact faces should be
slightly domed to ensure point contact. There
is no need
to remove the pitting from the fixed
contact.
When reassembling, the nylon bush is fitted
through the low tension connection tab, and
through the spring location eye.
Apply a smear
of grease to the C.B. cam and moving contact
pivot post. Every 3,000 miles and/or contact
replacement, apply two drops of clean engine
oil
to the rear of the three lubricating felt
wicks.
H3 PART E. CHECKING THE HIGH
TENSION CIRCUIT
If ignition failure or mis-firing occurs, and the
fault
is not in the low tension circuit, then
check the ignition coils as
described in Part C.
If the coils prove satisfactory, ensure that the
high tension cables are not the cause of the
fault.
If a good spark is available at the high tension
cable, then the sparking plug suppressor cap
or the sparking plug itself may be the cause of
the fault. Clean the sparking plug and adjust
the electrodes to the required setting as
described- in Section H4 and then re-test the
engine for running performance. If the fault
recurs then it is likely the suppressor caps are
faulty and these should be
renewed.
