damage, it may be an option to power the sidelight and/or tail light
according to the customer preference.
The Indicator Diode Test
Some machines require an in-line diode to be installed into the wiring
of the indicator circuit. To determine if this is required, carry out the
following test after installing the alarm:
With the ignition turned OFF, position the indicator switch of the
machine so it would be set to ash the indicators either right or left,
it doesn’t matter which way.
Position the light switch of the machine (if tted) so the lights would
be on if the machine was running.
Arm or disarm the alarm whilst looking at the dash lights and
instruments to see if anything other than the indicator repeater
lights works. If this happens with the indicator set to left or right; a
diode is required.
Arm or disarm the alarm and check to see if the headlight or side
light illuminates.
Test the starter button to see if the machine cranks (always check
the machine is in neutral and any interlock systems on the machine
are set to the run position, e.g. kill switch, clutch, side stand, etc.).
If during these tests any extra lights or instruments operate, the
alarm fuse blows or the machine cranks over, a diode will have to be
inserted in line with the input or output of the indicator relay.
Dioding the Indicator Relay
The diode can be tted in either the feed to the relay from the fuse
box or the output from the relay to the indicator switch, it doesn’t
matter which as long as it is connected the correct way round.
The input wire will be an ignition switched positive from the fuse box
to the indicator relay. If this wire is cut the band on the diode should
face towards the relay
The output wire is the feed to the indicator switch which provides the
pulsed output to ash whichever side indicators are selected via the
