- do not hold the key in the ignition switch in the "Ignition on" position for more than 10 seconds if the engine does not start;
- connect the tachometer in accordance with its operating instructions. Some tachometers may not be compatible with this ignition system;
- do not connect the ignition coil terminals to "ground";
- do not disconnect the battery terminals while the engine is running.
In an electronic ignition system, the ignition voltage is more than 30 kV. Under unfavorable circumstances (high humidity in the engine compartment) voltage peaks can break down the insulation and cause shock when touched.
To avoid injury or damage to the ignition system, keep the following in mind when working on the system:
- do not touch or disconnect the ignition wire with your hand while the engine is running or while the engine is cranking with the starter;
- disconnect the ignition system wires, connect and disconnect any measuring instruments only when the ignition is off;
- when heated above 80°C (for example, when painting a car), do not start the engine immediately after warming up;
- do not wash the engine while it is running;
- when carrying out electric welding work, disconnect the battery;
- persons with a pacemaker are prohibited from performing repair work on the ignition system.
