Checking protection and safety device components
Checking the key switch
Disconnect the ignition switch (A) from the wiring loom by opening its connector (Sect. P 1, Routing of wiring on frame) and use a multimeter (Sect. P 9, Diagnostic instruments) to check its internal connections as follows:
-
turn the key to OFF and connect a multimeter to contacts (1) and (4) to check electrical continuity (Sect. P 9, Diagnostic instruments concerning operation of the multimeter). The resistance reading should be near zero and, if present, the audible continuity signal should be emitted;
-
turn the key to ON and connect the multimeter to contacts (3) and (6) and then to (2) and (5) to check for electrical continuity. The resistance reading should be near zero and, if present, the audible continuity signal should be emitted;
-
turn the key to PARK and connect the multimeter to contacts (1) and (4) and then to (3) and (5) to check for electrical continuity. The resistance reading should be near zero and, if present, the audible continuity signal should be emitted;
-
turn the key to LOCK and connect the multimeter to contacts (1) and (4) to check for electrical continuity. The resistance reading should be near zero and, if present, the audible continuity signal should be emitted.
 Notes
The same checks can also be performed using the “DDS” tester (Sect. D 5, DDS tester).
Checking the sidestand switch
Remove the switch from the sidestand and disconnect the main wiring loom connector from the switch (see “Routing of wiring on frame”, Sect. P 1).
Use an analogue or digital multimeter (Sect. P 9, Diagnostic instruments) to check operation of the switch (see table).
 Notes
The same checks can also be performed using the “DDS” tester (Sect. D 5, DDS tester).

Checking the fuses
The main fusebox (1) is located on the right-hand side of the motorcycle and is accessed by removing the right-hand side fairing (Sect. E 2, Removal of the side fairings).
The fuses are accessed by removing the cover (2), which shows the ampere ratings and fuse positions.
For ampere ratings, refer to the “Wiring diagram”, Sect. P 1.
 Important
Before replacing a damaged fuse with a new one of the same rating, identify the cause of the problem.
 
A blown fuse can be identified by the breakage of inner filament (A).
 Important
Switch the ignition key to OFF before replacing a fuse to avoid possible short circuits.
 Warning
Never use a fuse with a rating other than the specified value.
Failure to observe this rule may damage the electric system or even cause fire.
 
As well as the fuses in the fuse box, the motorcycle has a 30 A fuse (2) located alongside the ECU to protect the electronic regulator (Sect. P 2, Regulator/rectifier).
