Electrical system

1. PRECAUTIONS

There are a number of important precautions to be taken before beginning to inspect or
repair the electrical system.
• Special attention must be paid to the polarity of the battery.
• Always check the condition of the battery on beginning any repair.
• Charge the battery away from the machine to avoid possible spilling of acid or faults in the
charger clips contacts that could damage an electronic component.
• Do not handle the battery or other connections with the ignition on or the engine running,
as this could damage electronic components.
• Do not fit bulbs in the lights or instruments that are different to those specified.
• Do not carry out welding with an electric welder or any operations that produce sparks
without disconnecting the coil/CDI, as this could damage this equipment.
• Before taking electrical resistance measurements, make sure that the part is not hot.
• All the connections must be clean and well-tightened.

2. GENERAL WIRING

Checks to be carried out on the wiring:
• Check visually that the wiring has not deteriorated or that the connectors and terminals
are not loose or dirty.
Any elements found to be in a poor condition must be renewed.
• If not defects are detected visually, cables of the same colour and diameter should be
checked for a circuit using a meter.
To carry out this check, the wiring needs to be disconnected.
• Cables of the same colour and diameter should have a circuit between them.
