Title: Dead 640
Post by: JMG on January 25, 2015, 06:55:26 am
My 640 died completely yesterday, it started normal, I rode 10 km everything perfectly fine and then suddenly nothing.  Nothing electrical works, not even neutral light.  No ignition, no indicators no lights ect..... Terminals are fine and so is the one fuse sitting right by the batery. I'm yet to check the battery itself but seeing as I've had no hassles up to now I don't see that a battery would just suddenly die.

You either have a dead short somewhere or a break in the wiring loom  - now the trick is to find it

Start at the ignition switch and work backwards from there back to battery - the wiring around the steering neck is usually the problem on bikes because of the movement of handlebars and chafe of the loom against the frame

Often the problem is at the actual key-hole.  If the open it up from the bottom and clean it out, you'll have sorted the problem.  (It happened to me)

Had it on a old Honda. Spayed quite a lot of q20 into the key hole

Silly little wire at the back of the battery shaved against chassis
