Warning: The high voltage generated by the contactless ignition system is extremely dangerous and can even be fatal under some circumstances. Do not touch the high voltage wires, distributor or ignition coil while the engine is running. When detecting damage to the high voltage circuit, use quality tools with well-insulated handles.
1. Extra precautions must be taken when working on the electrical system to avoid damage to semiconductor devices (diodes and transistors), and avoid the risk of electric shock. When working with the system, take into account the following points.
2. Always remove rings, watches, etc. before working on the electrical system. Even if the battery is disconnected, a discharge may occur if the component is grounded through a metal object. This may cause an electric shock or electrical burn.
3. Do not mix up the battery connections. Components such as the generator or other semiconductor circuit parts may be damaged.
4. If the engine is started using large-gauge cables from an additional battery, connect the battery poles positive to positive and negative to negative. This also applies when connecting the charger
5. Never disconnect the battery terminals or the generator multi-terminal plug while the engine is running.
6. Before performing electric welding on a vehicle, it is necessary to disconnect the electrical wiring of the battery and generator.
7. Never use an ohmmeter with a hand generator to test a circuit.
8. Engine control units are very sensitive components and some precautions must be taken to avoid damaging them.
9. Units installed under the hood may be exposed to high temperatures or humidity. When welding or washing, be careful not to damage the unit. If this cannot be avoided, remove the unit from the vehicle and protect the wiring connector with a plastic bag.

10. Always make sure the ignition is off before disconnecting electrical wiring or removing components.
11. Do not attempt to troubleshoot using a test lamp or multimeter, as this may damage the unit.
12. After working on ignition/engine management system components, check that all wiring is properly connected before reconnecting the battery or turning the ignition on.
13. It is not possible to test the ignition system using a Hall effect generator in the distributor. When connected to a distributor or Hall effect generator, the test equipment, which uses its own power source, (for example an ohmmeter), will be damaged.
