I recently purchased a 2000 KTM 640 Adventure and have put lots of time and money into it just trying to get it road worthy. One thing I am trying to find out is whether the Temp idiot light is working or not. I don't want to rebuild the engine again. Is the light supposed to come on when the ignition is switched on and go out when the engine is started? Mine doesn't come on and hasn't when I have test ridden it for the first couple of miles. Which is good, I guess. Is there a way I can test the light and/or sender to make sure it is working properly? Thanks!
