CAPONORD 1200
The two throttle cables (opening and closing) actuate on a scroll mounted on a shaft which is sent back
to its home position by a return spring. On the shaft covers there are 2 double track potentiometers (4
control tracks) by means of which the torque demand is read (and checked). The 4 potentiometers are
tinned and magnetically controlled (contactless); they cannot be overhauled nor replaced
Level in electrical circuit diagram:Throttle grip position sensor.
Location:
•
on the vehicle: left side, under the filter box
•
connector: on the sensor
Electrical characteristics:
•
Not detected by a multimeter as they are contactless: read the voltage of the 4 tracks by the
diagnosis instrument.
