On a short ride the other day the bike just died on the road. Pulled over and when ignition turned on I get a rapid clicking from the main relay.
I found this video describing it exactly but no clues as to root cause or fix:

Battery is 100% charged and is holding charge. All lights work fine. Starter motor turns over fine but bike will not start. No fuel pump or exup sounds either. If I disconnect the relay the exup does cycle.

I replaced the main relay with a new one but sadly that did not fix anything. Same rapid clicking.

Any ideas are most welcome!
Thanks

I would venture a guess that it's a bad earth or a bad connection on the starter switch, the relay base or a joint in the loom. Either way, the relay is not getting a constant trigger signal but rather a pulsed one.

Problem solved! It was the connection to the fuel pump. Once I cleaned up the terminals inside the snap connector all was good again.

Thank you for responding with your findings and your solution to the problem. It will hopefully help someone else in the future

Thanks mate, literally have the same problem.
