Safety measures when working with electronic ignition systems

The voltage generated in electronic ignition systems reaches 30 kV. Under adverse conditions, such as high humidity in the engine compartment, this voltage can break through the insulation, and if you accidentally touch live parts of the system, you can get an electric shock.

To avoid personal injury and damage to electronic components, when working on a vehicle with an electronic ignition system, keep the following in mind.

Do not touch or disconnect the wires of the ignition system while the engine is running and starting.

Disconnect and connect wires of the ignition system, as well as wires of measuring instruments, only with the ignition off.

Do not connect to terminal "1" ("-") interference suppression capacitor or test lamp.

Before starting the engine with the starter (e.g. when checking compression), turn off the ignition by disconnecting the high-voltage wire (terminal "4") from the ignition distributor and connecting it with an auxiliary wire to "weight". The auxiliary wire must have the same cross section as the disconnected wire.

Do not start the engine from a fast battery charger for more than 1 minute at a voltage of more than 16.5 V.

Do not install an ignition coil of a different design on the engine (never install a coil designed for a conventional ignition system!).

Do not start the engine when the vehicle temperature is 80°C (e.g. stoving after painting, steam blasting, etc.).

Disconnect the wires from the battery before carrying out electric welding.

Wash the engine only with the ignition off.

It is forbidden to carry out work with the electronic ignition system to persons using a pacemaker.
