F650GS 2004. Had the bike 4 days and the indicators are acting strangely. Yesterday, they didn't work at all at the beginning of the journey. After a few miles, I tried them, and they were working, but at half speed, a very slow flash. By the end of the journey they were working normally. This morning, coming home from work, they didn't work at all. But when I got home, switched off the engine, and then tried them with ignition on but engine not running, they worked again - slowly, and gradually getting faster until after 30 sec or so they were normal.

I have never known indicators work in this way before, and I am stumped. Could it possibly be something to do with the immobiliser? The immobiliser doesn't use the indicators when arming or disarming, but the hazard switch was removed to give a location for the LED tell-tale. Possibly it is cut into the indicator circuitry somewhere? If not the immobiliser, what? Duff relay?

In my experience, indicators either work (normal) or don't work (bad relay, loose connection), or flash like mad (blown bulb). I've never known them go slower than normal unless the relay is the wrong rating for the bulb wattage, but then they would be slow the whole time.

Any electrical wizards out there want to have a guess at what might be wrong? I won't have much free time for the next 2 weeks, but after that I will grab the circuit diagram and have a proper look. (And probably rip out the immobiliser.) Any clues would be very welcome, as I am mystified at the moment.
