THROTTLE REGULATED IGNITION
CONTROL SYSTEM (TRICS)
In 'TRICS', Ignition timing varies as per throttle opening.
Below half throttle, ignition timing changes from 16
0
to 30
0
in proportion to engine rpm. Refer graph1.

IGNITION TIMING AFTER HALF THROTTLE
Details of modifications in various parts are as under.
A) Throttle sensor : Throttle sensor is provided in
Handle bar. A signal is passed to C.D.I.Unit with the
help of this sensor as per position of throttle.
B) Gas control link : Gas control link is modified .
GENERAL PRECAUTIONS :
There are some important precautions to be taken
while servicing electrical system. Please follow them.
l
Do not reverse the battery lead connections. This will
burn out the diodes in the electrical parts.
l
Always check battery condition before condemning
other parts of an electrical system. A fully charged
battery is a must for conducting accurate electrical
system tests.
l
The electrical parts should never be struck sharply,
as with a hammer, or allowed to fall on a hard surface.
Such a shock to the parts can damage them.
l
To prevent damage to electrical parts, do not dis-
connect the battery leads or any other electrical
connections when the ignition switch is on, or the
engine is running.
l
Do not use a meter illumination bulb rated for other
than the voltage or wattage specified in the wiring
diagram, as the meter or gauge panel could be
warped by excessive heat radiated from the bulb.
l
Take care not to short the leads that are directly
connected to the battery positive (+) terminal to the
chassis ground.
l
Never replace a defective part without determining
what CAUSED the failure. If the failure was caused
by some other item or items, they too must be
repaired or replaced, or the new replacement will
soon fail again .
l
Make sure all connectors in the circuit are clean and
tight, and examine wires for signs of burning, fraying,
etc. Poor wires and bad connections will affect
electrical system operation.
l
Measure coil and winding resistance when the part is
at room temperature.
