Ducati Diavel Service Manual: The hands free relay
Introduction
This relay provides key on +15 power to all the devices on the motorcycle. Functionally, it replaces the conventional ignition switch.
Wiring diagram
The hands free relay receives +12 volt power directly from the battery via the main 30 a fuse. Hands free - 3: pin 3 on hands free system connection. "U": current consumers requiring +12 volt in key on state (key on +15). Pin 30 red/white wire (r/w), pin 86 black wire (bk), pin 87 red wire (r), pin 85 red/yellow wire (r/y)
Error codes
The hands free system generates no fault code in the event of a hands free relay fault.
Electrical characteristics and checking component
The relay contact must close (continuity between pin 87 and pin 30) when the internal electric winding is powered with 12 volts (pin 86 and pin 85).
