748 Ignition Relay

Discussion in 'Technical Help' started by Blah blah, Jun 27, 2026 at 11:35 AM.

  1. Is there something special about the Ducati one?

    Prepping for the MoT and the indicators are a bit intermittent with a loud buzzing from one of the relays.

    I trace it to the ignition relay, looks like a normal 5 pin so it's replaced. Then nothing at all. Put the old one back in and it's working.

    I check pins 30 and 87a, no connection on the old one but connected on the new one.

    87 and 87a connected on the old one but not the new one.

    The internet says that the new one is as it should be, but it doesn't work in the bike so I am confused

    Any help would be great, thanks

    Editted to add, that I know the indicators have a separate relay, but it was the ignition relay making the noise and the wiring diagram doesn't show 87a but there are 5 wires...
