Electric fan starter
The ignition system is integrated with the injection and is of the inductive high efficiency type.
The control unit manages two important parameters:
- Ignition advance
This is optimised according to the engine rpm, to the engine load, temperature and ambient pressure
With idle engine, it is optimised to obtain the stabilisation of the speed at 1450 ± 50 R/1'.
- Magnetisation time
The coil magnetisation time is controlled by the control unit. The ignition power is increased during the
engine start-up.
The injection system recognises the 4-stroke cycle and therefore, ignition is only controlled during
compression.

Digital multimeter
Check that the injection load 10A fuse No. 3 is in
good conditions.
Check that the 7.5A fuse No. 2 for the live control
unit is in good conditions.
Check there is voltage between pins 22 and 26 of
the interface wiring for around two seconds when
switching to «
ON
».
