is to drain off excess power generated when only the side lights
are in use and to convert it to heat which is dissipated by the
air stream. When the main headlamp is in use, the resistor is
switched out of the circuit so that full current is available to
meet the increased electrical demand.

If the pilot light burns out with recurring frequency but the
headlamp is unaffected, the resistor should be suspected.
Because it is a sealed unit a new replacement should be fitted.
For those with the necessary equipment the resistor can be
tested. Connect a multimeter, set to the most sensitive
resistance function, between the brown wire terminal and earth.
The correct resistance for the unit fitted to CG125-C and E
models is 2 ohms; a similar reading can be expected from the
unit fitted to earlier models. If the reading obtained is
significantly different, the resistor must be considered faulty and
renewed.

18 Wiring: layout and examination
1
The cables of the wiring harness are colour-coded and will
correspond with the accompanying wiring diagrams.
2
Visual inspection will show whether any breaks or frayed
outer coverings are giving rise to short circuits which will cause
the main fuse to blow. Another source of trouble is the snap
connectors and spade terminals, which may make a poor con-
nection if they are not pushed home fully.
3
Intermittent short circuits can sometimes be traced to a
chafed wire passing through, or close to, a metal component,
such as a frame member. Avoid tight bends in the cables or
situations where the cables can be trapped or stretched,
especially in the vicinity of the handlebars or steering head.
