This system functions in a similar manner to the transistorised system described in Part B of this Chapter. In addition, it incorporates an electronic control unit which adjusts the ignition timing electronically according to engine speed, load and temperature. The distributor is not fitted with centrifugal and vacuum advance mechanisms.

Precautions
The precautions listed in Parts A and B of this Chapter apply also to the FEI system.

Note also the following: a) A digital multi-meter should be used for testing, otherwise readings may be inaccurate
b) When using a multi-meter, do not switch between ranges during testing as this may damage components
c) Do not under any circumstances use a test lamp, as this will damage the electronic components of the system
