I am reading your comments on the drive speed sensor with interest. I have a faulty speedo problem on my Dec 02 LT. I have examined the cable on the swinging arm as suggested on this site, and it was starting to wear. However, this is not where my fault is being caused because after ensuring that this point was OK, I still get the speedo working for a week and then not working for a week or so.
One thing that could help me to diagnose this it to monitor whether I am receiving a signal from the sensor, does anyone know what to look for? Is is simple Open / Close circuit? If so, what kind of speed is it opening and closing at, can I use a meter or would I need a scope? Or is there a voltage I should attempt to read, again can I look at it with a meter, DC or AC? Any ideas?
The reason for asking is that when it fails, it takes a few weeks to come back so it is really difficult to diagnose until I know what to expect to see coming up the wires. Of course when it is working, it is impossible to diagnose.
Finally, any practical suggestions as to how to diagnose when the bike is stationary?
Thanks in advance for your time,
