1. Fuse
Blown
Check cause, repair and replace fuse
2. Fuse
Not Blown
Is there power to the fuse?
Q. Is there
power to the
fuse?
A. Yes
Check Earths to the alarm
Check connection block of alarm and pins within
Check for intermittent breaks in both the 12 volt pos and neg supplies by
moving the wiring harness, fuse box, etc
Repair/replace above faults as required
Check the machine earths and earth links/connections
Loss of power
(Not S4 Yellow)
Q. Is there
power to the
fuse?
A. No.
Is the battery charged and connected? Check BOTH pos and neg
Is the main fuse of the machine blown? Cure fault and replace
Is there a break in the harness? Move loom or check down loom with a
multimeter.
Q. Is this in
damp/wet
conditions
A. Yes
Check all connectors within the machine, particularly the ignition barrel,
rectifier/regulator and starter solenoid connectors. A careful water test
may assist. Clean/repair/re-wire/re-route as required
Check the OE and alarm harness for water ingress and voltage tracking.
Test ignition switched wire of the alarm for voltage whilst water testing
Ignition trigger
Q. Is this in
damp/wet
conditions
A. No
Check the OE harness particularly around the headstock area for internal
damage/shorting. Repair as required.
Check the harness in the area of the alarm connections for poorly
insulated joints. Repair as required.
Check any area of the machine where loom damage could take place.
Repair as required.
Movement trigger
(Not S4 Yellow)
Q. Is the
machine actually
being moved?
A. No
Adjust movement sensor within the engineer software switches to a higher
setting (engineer switch 4, default setting is 3)
Nudge trigger
Q. Is the
machine actually
being nudged?
A. No
Adjust nudge sensor within the engineer software switches to a lower
sensitivity to impacts (engineer switch 5, default setting is 8).
The lower the number of flashes, the lower the sensitivity.
Adjust via the engineers switches, the number of impacts within any two
minute period to a greater number (engineer switch 8, default setting is 2,
i.e. 1 warn away and trigger on second nudge).
Please note: Sometimes it is advisable to adjust BOTH the above
software switches at the same time.
Trigger line 1
Q. Is the switch
correctly
adjusted?
Adjust switch as required and re-test.
Check the connections to the switch.
Test the alarm plugs are correctly fitted and the pins are correctly located.
Q. Has the
switch come
detached?
Refit correctly and securely.
Q. Is the panel
being protected
from removal
fully secured or
loose
Fit the panel with the correct fixings or adjust the switch position to take
account of the problem.
Q. Is trigger line
2 connected?
A. No
Try a water test to see if the alarm triggers on trigger line 2. If it does
either connect trigger line 2 to a good earth or insulate the end correctly.
Test the harness to ensure the wire has not been trapped or the insulation
damaged and repair as required.
Trigger line 2
(Not S4 Yellow)
Q. Is trigger line
2 connected?
A. Yes
Check the circuit the trigger line is connected to for any faults or damage to
the switch arrangement/harness and repair as required.
Temporarily disconnect the second trigger line from the circuit to see if the
problem is eliminated. If it is, locate the problem and re-fix the trigger line.
