The 2 wires for the side stand switch. Do I join them together or earth one of them. If so which one.
Brad.

its a switch, open or closed. you don't earth one of them *
I think you have to link the two wires to override the switch, (makes sense when it should be fail safe)

edit *, unless one of the wires normally goes to earth (chassis), and then you can locally earth the other at the control unit.

Don't know the zx10 electrics but if there's 2 wires I'd guess the switch makes/breaks the circuit between them rather than going to earth. In which case I'd say connect them together*
Have you got a wiring diagram? Should be possible to tell from that.

* Or leave them apart depending on which way the switch worked.

Thanks for the info.
My guess was to link both wires but just wanted to check.
The wiring diagram shows both wires connected at the switch but not too sure how the switch works from the diagram.

It could be the switch breaks when the stand is up (pretty unlikely) so I'd leave the connection so you can get at it if that does turn out to be the case.

Be warned - this is often NOT as simple as meets the eye...

The majority of post-2000 sportsbikes use this binary switch position, often alongside the clutch switch and gear position sensor, to determine fundamental running conditions of the machine such as RPM limits and fueling duty cycles. For example...

If sidestand is <down> and clutch <pulled in> and gear position is <N> the bike will run and rev (but possibly with a slightly lower rev limit to prevent no-load over-rev).
If sidestand is <down> and clutch <pulled in> and gear position is <1> engine will cut out (to prevent you riding away with the sidestand down).
If sidestand is <up> and clutch <pulled in> and gear position <1> engine power may be limited (to protect the rider and/or engine).

Simply cutting/bridging might appear to have the desired affect as the engine may still start, but will lead you on a wild goose chase when you realise it's lacking 50% power, or only revving to 75% etc. Loads of stories of this in the 2-wheeled fraternity.

Hope this helps!

Thanks for the info Rob.

It can only be one of 3 configurations.
But your info will help if there are any issues.

This is the ZX10R switch diagram.
