Ok brains trust...im stumped.
Problem is a few weeks old. Ill describe it and list what Ive done.
PROBLEM:
* While riding, the bike will (seemingly randomly) start rapidly flashing the headlight and instrument lights
* All other functions of the bike are fine. There is no power loss - nothing at all except for flashing headlight/instrument lights
* Sometimes while this rapid flashing is happening, the indicators will also both flash
* It mostly only happens when the bike is warmed up and most often happens above 100kmh
IVE TRIED:
* replaced handlebar switches with spares
* cleaned and reseated all obvious electric connectors (ECU, tank, Ignition computer, all handlebar switch connectors, grounds, alternator, starter, battery - all good)
* replaced fuses
* checked my headlight relay wiring for issues and switched all lighting relays.
* starter motor was rebuilt with new bushes about 20,000kms ago (18 months)
* battery is fine
I havnt pulled the instruments as I also need to remove the nose fairing and im lazy, but im about to do it now.
I also havnt changed bulbs as Im cheap.
While sitting here typing this - the tank, seat ecu are all removed - but the ignition key is turned on...the bike just sitting there with the key on...and BOTH indicators just started flashing like hazard lights.....? WTF?
