Safety precautions when working with an electronic ignition system (Mondeo 1)

In electronic ignition systems, the ignition voltage is up to 37 kV (kilovolts). In unfavorable conditions, such as high humidity in the engine compartment, peak voltages can break through the insulation, resulting in injury (electric shock) when touching the parts. To prevent injury to personnel and/or damage to the electronic ignition system, the following provisions must be strictly observed when working on the electronic ignition system:

Do not touch or disconnect spark plug wires with your hands while the engine is running or the starter is engaged.

The ignition system wires can only be disconnected when the ignition is off.

When the ignition is switched on, all spark plug connectors must be connected. If an ignition spark test is required in an emergency, such a test can only be performed using a spark plug in one cylinder. In this case, it is necessary to ensure good contact between the spark plug and the ground. The spark plug tip must not be held on the ground with a bare hand; well-insulated pliers must be used for this purpose.

Connecting and disconnecting the wires of measuring instruments (tachometer/ignition tester) is only possible with the ignition switched off.

In case of heating to a temperature above +80°C (e.g. varnishing, steam jets), the engine must not be started immediately after the heating stage.

You can wash the engine only after turning off the ignition.

When performing welding work, completely disconnect the battery.

Persons with pacemakers should not perform any work on the electronic ignition system.
