WARNINGS

• Do not attempt to run the engine when the battery earth wire is disconnected. You could severely damage the wiring.
• Never pull or tug at wires or wiring. You could extract the wires from the connectors or terminals.
• Disconnect all the ECU's and other electronic devices before performing arc welding operations on the body.
• Before replacing a fuse always check whether the circuit it protects is faulty.
• When you replace a fuse, always check the amperage is the same. Never use higher or lower amperage fuses.

PRECAUTIONS

When operating on electric components always attain to the following precautions.

• Remove rings, wrist watches or other metal objects.
• Before intervening on the electric system (connectors, electric devices, wiring, etc.) DISCONNECT THE BATTERY.
• Beware of electric arcs. Although the battery voltage is 12V, the battery can output high currents in the event of a short circuit. This can cause arcs or sparks which can be dangerous to the operator or could be the cause of fire.
• Beware of high voltage. The electronic ignition system can generate voltages of 20,000V or more. This can be extremely dangerous. Work with extreme caution on or near components.
