To prevent serious damage to the electrical and electronic components, never try and start the engine with the battery earth lead slack.Never pull the leads or wiring using force because this would result in the cables being disconnected from the connectors or terminals.Disconnect all the control units and electronic devices when carrying out arc welding operations on the bodyshell.Before replacing a fuse, check that the circuirt protected is not faulty.When replacing fuses, make sure that the new fuse is the correct amperage. Do not use fuses that have a higher or lower amperage than required.
PRECAUTIONS
When working on electrical components always follow the precautions described below very carefully:- Remove rings, wrist watches and other metal objects.- Before working on the electrical system (connectors, electrical components, wiring, etc.) turn the ignition key OFF and DISCONNECT THE BATTERY.- Take care over electrical arcs. Even if the voltage is 12V, the battery can produce high currents if there is a short circuit, creating arcs or sparks that can be dangerous to the mechanic or create a fire hazard;- Take care over high tension. The electronic ignition system produces voltages of 20,000V and more which could be very dangerous. Take great care when working on or near these components.- Avoid fire risks. Do not smoke when working close to the battery or components which get hot during usage (e.g. halogen bulbs) or in the area of the engine compartment when the engine is still hot.
