Safety in the repair of electronic ignition system
In electronic ignition systems secondary voltage up to 30 kV. Under unfavorable circumstances, such as at high humidity in the engine compartment, the voltage peaks can penetrate the insulation. If in this case come into contact with parts of the ignition system, it may cause electrical shock. To avoid injury to persons carrying out these works, and / or damage to the electronic ignition system, with maintenance work in cars with such a system should pay attention to the rules set out below. When the engine is running or when you start it, do not touch hands high voltage wires and not contracted his hands. Only when the ignition is off, disconnect the wires from the terminals of the ignition system, particularly the multi-plug engine control device. Every electrical circuit high voltage must be loaded with a resistor having a resistance of not less than 2 k, t. E. When the ignition must be mounted contact tips of spark plugs. Only when the ignition is off, connect and disconnect the wire plug gauges (tachometer / device for checking the ignition system). On the terminals 1 (-) and 15 (+) ignition coil can not connect a control bulb. If the maintenance vehicle require testing flammable sparks, then it should be done only with the use of spark plugs directly into the cylinder. At the same time provide good contact with the body of the spark plug of the car. Contact tip spark plugs or high voltage wire not hold his hand, and a well-insulated pliers in relation to the car body (such as the engine block). Before determining the speed of a starter check the compression pressure, turn the ignition off and remove the plug (A) on the HFM-regulating device or position sensor of the crankshaft (L5) on the PMS-regulating device. Fasteners primary circuit voltage is carried out up to 400 volts! Therefore it is always necessary to connect the clamps / packet core to the body of the car. When electric and spot welding, disconnect the battery terminals on-board electrical network. Wash engine only if the ignition is off. Persons with a pacemaker should not be working with an electronic ignition system.
