Touch all electrical wires and instrument connections and connect and disconnect them only with the ignition off.
If the engine should only be rotated by the starter, but not started, then the ignition must be turned off (neutralize).
When washing the engine, the engine must not be running and the ignition must be switched off.
To start the engine with a discharged battery using a starting device, it should not be connected for more than one minute and its voltage should not exceed 16.5V.
If a defect is found or suspected in the afterburning system for towing a car, the ignition must also be turned off (neutralized).
Do not connect a capacitor to terminal 1/- of the ignition coil.
Rotor (slider) the ignition distributor should not be replaced with any, but only with a resistance of 1 kOhm and the designation «R1».
For thick high-voltage wires, use only wires with a resistance of 1 kΩ and a plug of a candle with a resistance of 5 kΩ.
Shutdown (neutralization) ignition
For some work on the engine, the engine must be cranked by the starter but not started. In order not to damage the ignition and injection control unit, and the final stage of the ignition transformer. the 3-pin plug of the Hall sender on the ignition distributor or, in the case of KE-Motronic, the plug on the power output stage of the ignition coil must be pulled off.
