WARNING

ALL CONTINUITY TESTS MUST BE CARRIED OUT WITH THE CORRESPONDING CONNECTORS DISCONNECTED.

TAIL LIGHTS AND LICENSE PLATE LIGHT LINE

1) Check that bulbs operate properly.

2) Check fuses No. 1 and 7.

3) Check key switch contacts.

4) Check if there is voltage between the Yellow-Black cable of fuse No. 7 and the ground. If not, check cable harnesses.

5) Check that the cable harnesses of the bulbs and their ground connection are not interrupted.

HIGH BEAM/LOW BEAM LIGHTS LINE

1) Check that bulbs operate properly.

2) Check fuses No. 1, 3 and 6.

3) Check key switch contacts.

4) Check if there is voltage between the Grey cable of the headlight relay and the ground connection.

If there is not, check the cable harnesses.

5) With the key switch set to "ON" and the engine running, check if there is voltage between the Yellow- Red cable of the headlight relay and the ground connection. If there is not, check the cable harnesses.

6) Check that the White-Black cable connecting the headlight relay switch and the control unit (pin 19) is not interrupted.

7) Check the headlight remote control switch.

8) Check that the Grey-Red cable of the light switch and the headlight relay switch is not interrupted.

9) Check the light switch contacts.

10) Check that the cable harnesses of the bulbs and their ground connection are not interrupted.

Fuses

The electrical system is equipped with:

1. six protection fuses "A" located in the glove compartment to the left

2. one fuse "B" located under the helmet compartment on the left fairing.

The chart shows the position and specifications of the fuses in the vehicle.

CAUTION

BEFORE REPLACING A BLOWN FUSE, FIND AND SOLVE THE FAILURE THAT CAUSED IT TO BLOW. NEVER TRY TO REPLACE THE FUSE WITH ANY OTHER MATERIAL (E.G., A PIECE OF ELECTRIC WIRE).

CAUTION

MODIFICATIONS OR REPAIRS TO THE ELECTRICAL SYSTEM, PERFORMED INCORRECTLY OR WITHOUT STRICT ATTENTION TO THE TECHNICAL SPECIFICATIONS OF THE SYSTEM CAN CAUSE MALFUNCTIONING AND RISK OF FIRE.

Sealed battery

If the vehicle is provided with a sealed battery, the only maintenance required is the check of its charge and recharging, if necessary.

These operations should be carried out before delivering the vehicle, and on a six-month basis while the vehicle is stored in open circuit.

Besides upon pre-delivery it is therefore necessary to check the battery charge and recharge it, if required, before storing the vehicle and afterwards every six months.

INSTRUCTIONS FOR THE BATTERY REFRESH AFTER OPEN-CIRCUIT STORAGE

1) Voltage check

Before installing the battery on the vehicle, check the open circuit voltage with a standard tester.

• If voltage exceeds 12.60 V, the battery can be installed without any renewal recharge.
• If voltage is below 12.60 V, a renewal recharge is required as explained in 2).

2) Constant voltage battery charge mode

• Constant voltage charge equal to 14.40 to 14.70V
• Initial charge voltage equal to 0.3 to 0.5 for Nominal capacity
• Charge time:
  10 to 12 h recommended
  Minimum 6 h
  Maximum 24 h

3) Constant current battery charge mode

• Charge current equal to 1/10 of the battery rated capacity
• Charge time: Maximum 5 h
