Connection
to dual ignition
system.
12.1.2.1) Tachometer 966 072 rflith resitor integrated
in coil kit:
The
generator
integated in the
DUCATI dual ignition has a
spe-
cial
grey
cable
for tachooeter
con-
nection.
The tachometet 966 O72
has to be fitted between the
giey
cable and mass
(brcwn
cable).
On the coil kit 996 845 a I kO
resistor is connected in series in
front of the
grey
cable
(iU.
30/1
).
12.1.2.2) Tachometer 966
072
with
externally fitted r€sitor:
In
case of a short-circuit in $e
cable
leading
to the tachometer this
resistor is
foreseen to avoid igni-
tion troubles. If
this
resistor
is de-
fective, itmust be removed. In
rhis
case contact
your
dealer.
Then this resistor in fiont
of the
grey
cable must
be
replaced
by a 1
kQ resistor
866
466 and
shrink tube
860 621 and be installed in the
grey
cable in
series-connection
(see
ill.
302).

12.1.2.3) Tachometer
966 074 with intecrated resitor:
If the lew tachoneter
966 074 is
used, no such resistorhas to be in-
stalled
(alrcady
integated in
this
tachometer). Refer ill. 30/3.
