I wonder if anybody can throw a bit of light my way.
A few months ago I posted that my indicators & hazard lights had suddenly stopped working. At the time of this discovery I also noticed that when either indicator button was pressed the digital clock faded into nothing. I later found the hazard switch had a dodgy solder in one of the wires under the handlebar pad. Once this was re-soldered both my indicators & hazard were functional again (and the clock remained visible)
Fast forward to yesterday, and coming back from work once again the same thing started happening (no indicators/hazards & clock fading). My first obvious port of call was checking the integrity of the hazard switch again. It seems fine. But now I notice that there are some strange noises coming from the relay box under the tank. The sound is almost like a fast high pitched whirring. Hard to describe.
There is a slight difference in sound between the indicators and the hazards and they appear (though I could be wrong) to be coming from different relays.
Are there different relays for the indicators and hazards?
Does anyone have a diagram of what the relays are?
Am I even looking in the right place?
My bike is a 1990 16v.
