When servicing electrical components, special precautions must be taken to avoid the risk of failure of semiconductor elements and to prevent electrical injuries. Remember that the generator and starter are directly connected to the battery and can cause a fire if overloaded or short-circuited. Try to keep hair and loose clothing away from the generator drive belt.
When servicing electrical equipment, be sure to remove wristwatches, rings, and other metal jewelry. Even with the battery disconnected, the discharge of capacitors when their terminals are accidentally grounded can result in electric shock or severe burns.
Do not reverse the polarity when connecting the battery. Components such as the generator or electronic control units contain semiconductor elements that can be damaged if the wires are connected incorrectly.
When starting the engine from an external power source, or connecting a charger, also observe the polarity of the wire connections.
Never disconnect electrical wiring from the battery, alternator or diagnostic equipment while the engine is running.
Do not allow the engine to turn over the disconnected generator.
Never test the generator output voltage by grounding its terminals.

Do not use ohmmeters equipped with a hand dynamo to check for continuity in a circuit.
When performing any electrical maintenance work, make sure the negative cable is disconnected from the battery.
Before using arc welding, always disconnect the battery, alternator and components such as the fuel/ignition ECM to avoid the risk of damage.
