Repairing the Headlamp
The headlamps should be inspected and repa ired in the case of
<my rep<!irs involving the di s mantling of the motorcycl e.
To correctly perform lhe wiring in the headlamp, take note of
the wire colouring according to the diargam attached to the head-
lamp body.
When inspe c ting the h ead lamp , mak e sure that the terminals arc
reliably connected to the sw itch panel as the loose termimlls will
crea te a high transient resistance and the pilot lamp will glow
weakly with the current-and-voltag e regulator operating c orrectl y.
The
optical element s hould be disassembled only during repla-
ceme nt of the diffuser, taking care to avoid touching th e mirror sur-
face of the reflector.
In
exceptiona l cases the reflector should be washed in a c lean
w arm water by rnaking circular movements with a cotton wool pad
(avo iding pressing the pad to the reflecto·r surface) and periodically
c hanging dirt y water and ·pad. After washing, the refle ctor ha s to be
dried.
