20 Most Recent 2006 Triumph Daytona 955i Questions & Answers

I would be careful with wiring on modern bikes. If you have ANY doubt pay a professional to do it for you. There are sensors on modern bikes that can be affected if the voltage is wrong. Causing possibly expensive issues. Go back and check you have the correct R/R for your bike. Wiring can be different between years and models especially with aftermarket parts.

im having the same problem need help also

When there is no charging system operational, the bike will run wih battery in total loss mode. When it gets to a certain point of discharge, the first indication is indeed as you saw, the intruments go blank. There is little power left at this point and need to get home asap! 

Either the R/R (rectifier/regulator) and/or the stator is bad - both are unfortunately quite common failures on these bikes. 

You can find a diagnosis guide that I personally authored at this site: 
http://www.triumphrat.net/speed-triple-forum/104504-charging-system-diagnostics-rectifier-regulator-upgrade.html

Follow those guidelines and you will be able to determine which or both is failed.
Also is a recommendation for a retrofit/upgrade to a better component if you do need to replace the R/R. 

Hi, I assume it's the main fuse to or from the battery? Check for a loose connection at the fuse holder. At each point of the wires opposite to the fuse. Also if it is a blade type fuse holder, it's possible that the fuse is loose.(not a good tight fit) An in line fuse

check resistance / continuity of power wire from battery to coils / trigger

milky? could be condensation

What you are describing is absolutely normal. I wouldn't worry about it at all. you may find in cooler days the temp might come down a few degrees with the fan on, but on average to hot days it will stay high in traffic. Travelling on the open road you should find the temp ranges between 80 and 90 which will show that you thermostat is working ok ( opens at 82 degrees c )

dead battery or relay stuck.. i am having the same issue with my 2003 triumph speed triple.. turns over well but no spark no fuel in injectors.. ecu isnt telling it to start. dead battery? or relay?

the alternator is probly faulty-have it tested--inspect wire harness and connections for flaws--buy a clymer or haynes book repair procedures

this could also be an air bubble in the coolant system, change the coolant and check if there is a bleed nipple in a high point of the system like the thermostat housing. The thermostat or sensor dont usually cause an intermittant problem, Rpm change can indicate an air leak on the intake or lean mixture

The daytona 955 with the round tube frame was made of aluminum.. hope this helps him to get your bike fixed. Brian

Strip it down and trace the wiring for any damage or disconected plugs/terminals.

17MM

Is the ecu light on on the dashboard?

ok, first off is that when you "jump a bike" dont jump by car with engine running this can fry major componets second you can try the reboot but I do think you damaged one of the parts

Hi and welcome to FixYa,

To my understanding, the cooling fan is activated by the ECM. This is done by switching the yellow/black wire to ground. The activation is triggered by the coolant temperature sensor that feeds signals to the ECM. Ideas to consider:

• verify integrity of connections of coolant temperature sensor (purple/black & purple/green wires) to the ECM;
• check, clean or replace the coolant temperature sensor itself;
• bypass ECM and install a manual override switch plus dual reverse protection diode on the 2 yellow/black wires from the cooling fan wire connector.

Good luck and thank you for asking FixYa.

can you get to the rectifier? it cinsists of 4 diodes, i would expect to find one shorted both ways and eating lots of amps, the other one would still give some charge to the battery.

Yes, dry needle bearings can make that sort of sound. I suggest a complete teardown and inspection of all the bearings in the rear suspension. Replace any that are rusted or otherwise worn excessively, then re-pack each with the recommended grease upon reassembly.
To prevent premature failure in the future, avoid directing high-pressure water spray at these areas when cleaning your bike.

Can you hear the fuel pump 'prime' when you first turn on ignition? You should hear the pump run (whine) for 3 secs or so after key first on.

The '98 has a notorious problem associated with the 'ground block' which is a common node point for all the return wires for the battery -ve.
There is a replacement/upgrade for this part which includes a new block and additional wire back to the battery -ve terminal

The part number you need is Triumph part number T2505055 and is under $10. Good idea to replace this whether the primary cause of your problem or not (good likelihood it is however)
