The starter has a freewheel clutch with preliminary engagement with the traction relay. When the engine is started, the traction relay moves the pinion, bringing it into engagement with the flywheel ring gear before the starter is activated. After the engine is started, the freewheel clutch prevents the transmission of rotation from the engine to the starter.
More detailed information on the various systems can be found in the relevant Chapters of this Section. Although repair operations are given in some cases, the usual action is to replace the faulty component.
When working on an electrical system, extra care must be taken to avoid damaging semiconductor devices (diodes and transistors) and avoid electric shock.
Always remove rings, watches, etc. before working on an electrical system. Even with the battery disconnected, capacitive discharge may occur if the component's power terminal is accidentally shorted with a metal object. This may cause an electric shock or severe burn.
Do not mix up the battery terminals. Components such as the alternator, electronic control devices or any other semiconductor circuit may be irreparably damaged.
When starting the engine using large-section cables and a starting device or a separate battery, you need to connect the plus to the plus and the minus to the minus. This also applies when connecting the battery to the charger.
Never disconnect battery, alternator, any electrical wiring or instrumentation while the engine is running.

Do not allow the engine to rotate while the generator is disconnected from the electrical system.
Never test the generator's functionality by shorting its output terminals to ground.
When working on the electrical system, make sure the negative battery cable is disconnected.
Before using arc welding on a vehicle, disconnect the battery, alternator, and components such as the electronic ignition control device and fuel injection system to protect them from damage.
