PREPARATION FOR THE TEST ON DIESEL ENGINES

Connections to the vehicle

•
Connect the plug (35) of the revolution cable (38) to the socket (16) of the
timing light;
Piezoelectric transducer (18).
•
Connect the red clamp (15) of the supply cable and the red clamp (13) of the
volt cable to the battery positive pole (39).
•
Connect the black clamp (14) of the supply cable to the battery
negative pole (40).
•
Connect the sensor cable (37) to the socket (17) of the timing light and,
afterwards, to the socket in the motor compartment.
ATTENTION:
The timing light functions only with a 12 Volt voltage which, under ordinary
conditions, is supplied by the car to be tested.
In case of operation on vehicles having a different voltage, supply the instrument
through an external battery (so as to have a constant 12 Volt voltage) and remember to
connect the battery negative pole to the car chassis.
ATTENTION:
A possible polarity inversion in the connection between clamps and battery
does not allow the instrument functioning but does not damage it.
