Introduction to the electrical system of the Diavel
The figure shows the locations of the low beam bulbs (LO), high beam bulbs (HI) and the parking light LED light unit (1).
Rear view of the headlight showing the high and low beam light connections and the connection for the LED power module
at the centre, with the connector cable.
To access the tail light - turn indicators unit, remove the seat as described in Sect. 5 - 3,
tool tray cover as described in Sect. 7-17, "Removal of the tool tray".
The BBS and the Dash Board unit provide electric power to the lighting and signal devices, which therefore have no
conventional power supply passing via a fuse and no electric switchgear set on the handlebar. Commands for the lights
and signals are in fact sent to the control units, which then activate the relative lighting devices. The following table
indicates the types of devices used, the type of power supply and whether or not the devices are testable.
