ZENER DIODE LOCATION
H
The Zener Diode ("A" Fig. H 13) is mounted on
a bracket below
the headlamp, and the
aluminium heat-sink ("B" Fig. H 13) is finned
to assist cooling. The order of assembly is
shown in Fig.H 13.

To remove diode only, disconnect the
brown/blue double "Lucar" connector from
the diode. Remove
the black plastic plug from
the front of
the heat sink (See Fig. H131 and
unscrew
the "nyloc" nut which secures the
Diode.
When refitting, the Diode nut must be
tightened with
extreme care. (Maximum
tightening torque
22/28 Ib./in.)
Tak off
the finned heat sink, remove the
front bolt from
the retaining bracket. A

SECTION H8
ELECTRIC HORNS
DESCRIPTION
The horn is of a high frequency single note
type and is operated by a direct current
from the battery. The
method of operation
is that of a magnetically operated armature,
which impacts on
the cone face, and causes
the tone disc of the horn to vibrate. The
magnetic circuit is
made self interrupting by
contacts which
can be adjusted externally.
If the horn fails to work, check the
mounting bolts etc., and horn .connection
wiring. Check
the battery for state of
charge. A low
supply voltage at the horn
will adversely affect horn performance.
If the horn still fails to operate, make the
following checks:-
(11 Eliminate the horn push circuit by
earthing WI-terminal with a temporary
wire. If the horns then operate, check the
horn push
and associated wiring.
(2) Having carried out test one and the horn
still fails
to operate, apply a direct feed to
the hom with a temporary link.
If the above checks are made and the fault
persists,
then adjust the horn as follows:-
