Hi all

Hope you can help a dane here.
After 2 hours of ride yesterday and unfortunately 30 minutes of queue at the highway, which caused the fan to cool the engine, the temperature suddenly fell down to just one 'mark' at the display. Today there was no temperature shown at all in the display??
What has gone wrong? Some electrical issue or mecanical? Is it a known problem for some of the more experienced?

I will of course visit the local triumphdealer as soon as possible, but just want to know if I can take the bike the same way back tomorrow without overheating or damaging the bike?

Hope some of you know more ..?

Kondi, Ensure that the system has coolant (engine cold), check the fuses and ride home when there is the least chance of a traffic tie up. Other alternative is to tow it back as there is a possibility that the fan won't run when needed if the temperature sensor isn't working.

Good luck,
Brad

Thanks Brad

I'll check the fuses - thought of that aswell tonight. Otherwise I'll cross my fingers and drive all the way home tomorrow without any heating problems.
Lovely bike anyways!

Ok, just to let you know, the bike went all back to normal yesterday when I went back home on the highway. Ended up in the queue again, and no doubt the engine got hotter. But suddenly the temp bars on the display raised from 1 to 5 again. The fan started and I could continue on a "normal" bike the last 150 km.

Let's hope it was just an overheating confusion ...

ppffeww.

Kondi, Nice to read that. You might want to check the coolant temperature sensor operation should the trouble arise again. A better step may be to replace it ... alot cheaper than if the engine overheats for lack of the fan running.

Brad, are you sure the coolant temp sensor is part of the fan circuit? I don't know the 675s at all, but on the old 885s the coolant temp sensor is connected to the coolant temp gauge and the thermostat is what controls the fan. On those motors, you could replace the coolant temp sensor with a bolt and it wouldn't affect the fan's operation. Which is good, because they failed pretty often.

Kit, I don't know anything about the D675. Some FI ECUs use the temp sensor input to run the temp gauge and a radiator fan. The D955 seems to.

When Kondi has the dealer check out the problem it hopefully won't test okay.

Anybody know for sure? How about for Gen 2 955s? I can see from the diagram that my Sprint's temp sensor feeds into the ECU, so I'm tempted to assume it controls the fan, but I made the same assumption about the 885 and I was wrong there...
