Ducati 821 2013 Hyperstrada

Do you have the owners manual? It has a wiring diagram in it. You can get a copy from the Ducati website.

Presumably, your front indicators are still working? If so, you'll need to backtrack on the wiring until you reach the flasher unit, which is bound to be a pain. Good luck!

Hi,
Someone has suggested it's the bbs unit, apparently this feeds the rear indicators!....

I'm looking at the drawing now and it's a little disturbing. I'm used to 'old school' bike electrics and from what i can see, the input/output goes to control modules and not a separate flasher relay. The manual describes BBS as' Vehicle Control Unit'...YIKES! Does yours have OEM turn signals? I've never troubleshot a CanBus system but have worked around industrial controls for over 30 years. It appears that the control system is not necessarily 12volts DC. Be cautious in your efforts and don't introduce voltages that the modules will not tolerate. They may have in-circuit fusing that will fail when you introduce 12 volts into the 5 volt system.

This is from the factory owners manual for a 2013.
