WHEN WORKING ON A VEHICLE EQUIPPED WITH A MOTRONIC INJECTION/IGNITION
SYSTEM THE FOLLOWING PRECAUTIONS MUST BE OBSERVED:
- do not start up the engine with the electrical connection terminals not properly connected or
slack at the battery poles;
- never use a rap'id battery charger to start the engine;
- never disconnect the battery with the engine running;
- to rapidly charge the battery it must be disconnected first from the vehicle's electrical system;
- if the vehicle is going in a drying oven after painting where the temperatures are in excess of
80 °C, it is necessary to remove the injection/ignition electronic control unit;
- never attach or disconnect the electronic control unit multiple connector with the ignition
switch in the ON position;
- always disconnect the negative battery lead before carrying out electrical welding on the vehi-
cle.
Remember that this system has a memory which is always supplied (stand-by memory)
wherethe self-adjustment values are memorized. The operation of disconnecting the battery re-
sults in this information being lost but it can be acquired again after a certain mileage; this oper-
ation should therefore be restricted.

Position the clip in such a way that the head

speed.
