Electrical system
Pick-Up.
- Disconnect the control unit connector and con-
nect the positive wire to connector No. 2 and the
negative wire to connector No. 8 (see figure).
- The multimeter end of a scale should be 200V.
Use the start-up system to run the engine and
measure the voltage produced by the Pick-Up.
- Replace the Pick-Up if non-conforming values
are measured.
N.B.
THE MULTIMETER MUST BE SELECTED TO DETECT
CONTINUOUS VOLTAGE.
Specific tooling
020409Y Multimeter adaptor - Peak voltage de-
tection
Electric characteristic
Voltage value
> 5 Volt
- HV coil
With the control unit and HV coil connected, meas-
ure the voltage of the coil primary during the start-
up test with the voltage peak adaptor and con-
necting the positive terminal to the ground one and
the negative to the coil positive connector.
If non-conforming values are measured, replace
the control unit.
N.B.
THE PLASTIC CAP OF THE POSITIVE TERMINAL ON THE
