Got a problem with my GSXR 1000 k6. Hoping someone can help me solve it or at least point me in the right direction.
Bit of history on what has happened:
Had a problem with my instruments resetting occasionally for past 3 months or so (clock would reset, trip meter would round up to the nearest mile etc). It usually happened when starting the bike up. I use it every day for commuting so it is not standing unused for long periods.
Not sure if relevant but about 2 months ago my battery went completely dead (it was old) and the bike would not start obviously. Got a new battery and everything was fine. Then one day I left the parking lights on all day and drained the battery. Got my breakdown cover so AA came over and boosted the battery so I got the bike to start. Everything was fine since except the continued random clock resets.
Last week it started resetting more often and sometimes it did it when I switched on the high beam lights. Had a look at the left handlebar switches and the yellow wire to the high beam switch had a bit of insulation wrapped as if it would melt a bit (just about 1cm or so from the solder, the rest looks fine). Took the switch apart and it did show slight burning on that contact and it was really mucky. Cleaned it all off, insulated the melted cable bit with electrical tape and it all seems fine for 1 day.
Going to work a day after, I turned on my indicator and the whole instrument panel went dead (no speedo, gear indicator, rpm) and the headlight was not working. It all came back to life on its own about 10s later. Since then it happened few more times and usually it either came back to life on its own or I had to press indicators or hazards or highbeam few times.
Well… eventually it went dead and stayed that way :sad So this is what I need help with.
I will try to describe what is happening as best as I can:
What did I check so far:
Any help would be appreciated on what can be the fault or what to check next. Since it is just before christmas I would like to avoid getting the bike to a garage and spending a lot of money getting it fixed. Would prefer to at least try and diagnose it at home and use garage as a last resort.

I will try to describe what is happening as best as I can:
- Bike starts and runs fine
- Instrument panel - no backlight and nothing on the display except the neutral light
- Switching the ignition on, the rpm needle does not go up, but when switching ignition off it then goes all the way up and back down
- When ignition is on and I press the engine start button and hold it (no clutch so the bike would not start) it initialises correctly - rpm needle goes up and back down, backlight is on, display is working etc. and also the position (side) lights come on, It just looks as it should. When i let the button go it obviously dies. Also I noticed that the lights are still not working and neither do indicators. Pressing hazard on the position lights flash instead of indicators.
- All indicators are on but very dim
- Turning on indicators - correct one on the front is flashing but still very dim, the back one is at normal brightness and flashing
- Position (side) lights are on but dim
- Pressing the pass (high beam) the position lights go off completely
- Brake light works perfectly fine (front and back breaks)
- No low beam
What did I check so far:
- As mentioned at the beginning - left handlebar switches where yellow cable going to high beam switch looked like it overheated or shorted
- Checked the fuses and the main 30A fuse - all ok.
- Took the airbox off to get to the wiring harness and check quite a few connectors etc. all seem fine. Cleaned few connectors at the front, that go to the instrument panel and left switches, with a contact cleaner. Checked the regulator/rectifier connectors and all appear to be fine.
- Voltage on the battery is 12.83V. When ignition is on it drops to around 12.4V. Switching indicators on or high beam or start switch it drops a bit further but the lowest I have seen was around 12.1V.
- While looking at the wires I noticed that one brown wire (possibly with more markings) near the ecu plug (under the seat) was cut and insulated. No other cable looks to be touched. I reconnected it but did not change anything.
- Noticed that my regulator/rectifier is located under the seat just above the rear shock. Might be wrong here but shouldn’t it be at the front/left under the tank or radiator somewhere? Might have been relocated by previous owner but looks to be done professionally as it is all neat and tidy.
