GENERAL

Before starting to work, make sure that the ignition key is in the "parking" position and the battery cable is disconnected and, in any case:

  • avoid connecting the control unit output directly to the load;
  • absolutely avoid working directly on devices with cables connected to "positiv" or earth without firstly disconnecting the control units;
  • avoid short circuiting the sensors of the system unless otherwise specified;
  • before doing any electric welding disconnect the control units to avoid damage to the electrical components due to induced current.

WARNINGS: Work on systems foreseeing the possible consequences and avoid working on them when you are not perfectly aware of the characteristics of the components concerned. After changing a component of the electric system, you are recommended to replenish your stock with original Alfa Romeo spares. The use of other brands, with even only slightly different characteristics, may adversely affect reliability and safety in service.
