Safety precautions when working with ignition system components (Opel Frontera A)

            0

To avoid breakdown or damage to the ignition system, the following safety precautions must be observed during all work on the ignition system:

1. Do not disconnect the ignition cables while the engine is running or when the starter crankshaft is turning; do not touch or disconnect them with your hands. The tension is very high.

2. Disconnect the ignition system wires only when the engine is not running. The same applies to connecting test and measuring instruments. The ignition must also be turned off.

3. If the middle cable is removed from the distributor, it should be immediately connected to ground using an auxiliary cable. If this is not done, the engine must not be turned over by the starter under any circumstances (which is sometimes required for some checks).

4. You should avoid using a quick charger to help you jump start your car, as not every device is suitable for this purpose. If used, it can be connected for no longer than one minute with a maximum voltage of 16.5V.

5. When performing electric welding work, disconnect the battery (which needs to be done anyway because of the generator).

6. If the vehicle is towed due to damage to the ignition system, the control unit must be disconnected.

7. Only spark plug cables, rotor and caps specified for this model may be used.

8. Persons with a pacemaker are not allowed to work with the ignition system. People with heart disease should also be warned against working in the engine compartment.

9. Before disconnecting the battery, you must find out the code for the radio receiver that has anti-theft protection.

10. Before disconnecting the plug connection of the electronic control unit, it is necessary to switch off the ignition and wait at least 20 seconds. Otherwise, the unit may be damaged.
