^^Sounds like you have answered your own question.^^
The ECU disconnect symbol is usually a sign that the ecu is sending signals but they are not reaching their intended destination.It usually means there is a loose or corroded connection somewhere.Have a look at the multipin connector plugs under the tank.Its not unusual for a pin to get pulled out.
 
Hi i have looked at the plugs i can get to cleaned them but still no joy..
on the left side there is 2 plugs which joins to a big clump of cables that go down side of the frame do you no what these cables are some times when i wiggle these with ignition on the fuel pump primes like the ignition is turned of and on could this be the problem

ps can you buy new cable plugs and replace them to try sort the problem
cheers
 
At a guess I would say yes. If you can move the cables around, then they will be doing the same when riding. You need to trace them to their joints.

I've been looking for specific connectors for three years with no joy,,,,,,,,,,,if you find any or find a source Id'e be indebted to you for any info.
 
First thing I would do is check where the alarm wires are spliced in.Alarms have no place on a T.They drain the battery and can fook up the factory built in imobiliser.
When the engine dies,does the lights,etc still work?
Any warning lights displayed?
How old is the battery?
What is the voltage at the terminals?
Double check those multipin connectors,...the pins only need to be pushed out a tiny amount to not make contact.
Also have a look at the tip over switch,...may have come loose.
Check the operation of the sidestand switch,...mine died with a broken switch.

It does sound like a loose connection somewhere, but if your not confident enough to have a go, have someone look at it for you, but as you say
you could well end up paying through the nose.
 
Hi. I have noticed when the ECU is been displayed and it won't start when I tap the horn the error goes away then and it will start fine.
 
bigbo, kind of suggests an electrical problem if this should occur. Does sound strange tho'
Mind you, Italians can be that way too.
 
There's an error showing in dash board errors in the number 3 under memo anyone now what this is. DSC_0027.jpg
 
Afraid ma eyesight ain't up to that one mucker.
 
I no sorry rubbish pic. On dash board errors it as 1234 then active and memo it as a X in the memo of number 3
 
If you have dash errors,...disconnect the clocks and check/clean the electrical connections.Do the same with the ecu connectors.Use electrical contact cleaner,...not WD40.
There is a dash error table somewhere,but I'm fooked if I can find it.

The horn or the button?
Either way,the fault could be there somewhere.

Do you mean ECU?If so,yes.....that is if you can find a good one.
 
Yeah sorry ECU I have found one near buy for 50 quid so thought I would try it if it's Easley swooped but it's of a 06 mines a 08 will it be ok. ??
No I haven't stripped the lh switch but I tuck it for a run yesterday was going about 80 when it just died and ECU came up whilst rolling I git it into neutral pressed the horn and it just reset so started bike back up and carried on. It's weird.
Thanks for your help I no I'm a pain.
