my dash wont go on after i turn on the ignition, nor will the lights or horn. However the bike will turn over but not start. Checked all fuses which are not blown but i have no power at the fuse box for the dash, horn or lights? Checked all connections. The only light on the dash is the immoboliser light yet when the ignition is turn on this lights goes out which means the immoboliser is ok. The battery has a full charge in her. Help me please!!!
Fuses? Mine were playing up the other day. Some things working, others not. Just took em out, put em back in and all was well again
These systems are CAN and if one part fails such as your dash then the whole system shuts down. Hence no start!!
Check the main power fuses and when you pull them out you need to check that you have 12V at one of the terminals at least.
Did it die on a ride out or has it been flickering over the last week or so? The more info the better mate.

all the above have been done, fuses etc. My bike has been stripped down as all the street fairing and lights have been taken off for track stuff- The tank has been replace But used the old fuel pump in it. Surely you can remove lights without having a dead dash from it. Ive looked every were on the bike for a problem and i can't see anythink, plus why would i have no power at the fuse ways for some electrics but not the others?

strange one. I did something similar with my zx7r when turning it into a track bike.
I removed the sidestand and all the clutch switches etc but when I thought i'd bypassed the switch i'd actually ground them out and the thing wouldn't start as the fuel pump and starter circuit were dead.
It took me forever to find the bloody fault. Could you have done something similar?

All the sensors are linked as part of the "can" system , so air temperature, water temperature, ecu and ignition etc.
I am not sure that the brake switches are part of the can circuit but would assume the sidestand and clutch cut out are.
None of the above would explain a dead dash, that can only come from a complete power failure or the dash connector not being plugged in.
If you are blowing fuses , any fuses then you have a positive feed being shorted to ground.
Somewhere you have a postive feed cable shorting onto the frame or the loom has been pierced with a screw or even a wire has been cut in error.
Alternatively as the lights come on with the ignition on the later model there could be a sensor thats is not seeing the light's and therefore not allowing a complete power up.

Thats the problem i havent got blown fuses at all just deadd fuse ways for the lights and dash. I will look again all over for cut cables but i am sure i havent.

I had a dead dash the other day, also checked all the wiring,fuses ext all was fine.
Phoned a friend and he said I should check my battery connections, so I removed the battery and cleaned the terminals and the electrical connections to the battery.
That was all that was wrong.
Fired the bike up and rode the piss out of it..

Just check it,I might be wrong.

I will do mate. The connections are ok so I will change the battery but if the battery has enough grunt in it to spin the engine with ease then it should easily power a dash shouldn't it?
On CAN systems the ECU controls the power feeds to the various circuits, as part of the initialisation process it sends out a signal and expects a response, no response = shut down of that circuit.
This has to be your issue, my advice would be to start adding the removed items until your dash powers up. Make sure that the power is off before adding the components otherwise you could spike the ECU.

I will try this. Bearing in mind I have only removed lights nothing else if this is the case then how would you bypass it? I wonder if anyone else as had this problem, all im doing is sticking on a track fairing.
I don't have a wiring diagram for the new shapes, if anyone has access to one then post it up so I can take a butchers.
You say you have removed all the fairings, what have you done with the immobiliser ECU then as I thought that was bolted to one of the fairings?

According to the manual the dash is controlled by the ECU and will only fail if the CAN line is severed at some point. The immobiliser is not part of the CAN so it can't be the issue here, it would cause a non start but would not stop the dash from powering up.
The dash has within a code that responds to the ECU and allows the engine to start, if the dash has failed then the ECU would not allow the engine to start.
I think that you have a power feed issue at the 5A fuse that supplies the lights relay, horn, parking lights, indicators and dashboard. If this power feed is all intact then I can only assume that the dash has failed.
Sorry I'm not more help but it's hard to diagnose without getting my hands actually on the bike.

No thats great mate, I need to search round the bike again for possible cuts. Thanks for your help!
Shame I moved away all those years ago, I used to live just outside St.Helens. (Not a woollyback) LOL
