Warning: The high voltage generated by a non-contact ignition system is extremely dangerous and can even be fatal under some circumstances. Do not touch high voltage wires, distributor or ignition coil while the engine is running. Use quality tools with well-insulated handles when detecting faults in the high-voltage circuit.
1. Extra precautions must be taken when working on the electrical system to avoid damaging semiconductor devices (diodes and transistors), and avoid the risk of electrical 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 with the battery disconnected, discharge may occur if the component is grounded through a metal object. This may cause electric shock or electric burn.
3. Do not reverse the battery connections. Components such as a generator or others having a semiconductor circuit part may be damaged.
4. If the engine is started using heavy gauge wires from an auxiliary battery, connect the battery positive to positive and negative to negative. This also applies when connecting the charger
5. Never disconnect the battery terminals or alternator multi-pin plug while the engine is running.
6. Before carrying out electric welding on a car, it is necessary to disconnect the battery and generator wiring.
7. Never use an ohmmeter with a handheld generator to test a circuit.
8. Engine control units are very sensitive components and some precautions must be taken not to damage them.
9. Units installed under the hood may be exposed to high temperature 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. Before disconnecting electrical wiring, or before removing components, always make sure that the ignition is turned off.
11. Do not try to troubleshoot with a test lamp or multimeter, as you may damage the unit.
12. After working on ignition/engine management system components, before reconnecting the battery or turning on the ignition, check that all wiring is properly connected.
13. You cannot test the ignition system using a generator with "hall effect" in the distributor. When connected to a distributor or generator with "hall effect", test equipment that uses its own power source (e.g. ohmmeter), will be damaged.
