I've just set about trying to disable the side-stand switch on young Cassie's bike thinking it would be a really easy job as (I presumed - and thereby hangs my downfall) that there would only be two wires which would have to be cut and spliced. Imagine my shock/horror/dismay (delete where applicable) when I cut back the insulating tape to find four, yes FOUR wires all visibly going to the side-stand switch. The wire colours are;
Red
Yellow with red stripe
Black with white strip
Green
Does anyone out there have any ideas which should be spliced to which?
Cheers
what bike is it?? the best thing to do is remove the side stand switch and put a meter across all the contacts. you will probably find that there is a switch to tell the bike the stand is fully up and fully down. Have a look on the webfor the wiring diagram for the bike. A word of warning about removing the side stand switch. remove it and there is the potential move off with the stand down. the worse case is that if the bike is in gear and the bike on the stand when you start it, bike ends up on the floor.
Cheers for that peeps,the problem i'm having is the side stand switch kicking in at inappropiate times(quite a common problem with chinese bikes)which is at best a pain in the a**e and at worse quite dangerous.best solution seems to be disconnection.
Yep, I'd def get the old multimeter out, and do a continuity test acrosss two wires at a time with the side stand up, then with the side stand down, and of course as I have a "spreadsheet mentality", write down the results, so you''re not re-testing.
PaganPrince is prob right with the One pair for up, one pair for down. A continuity test will tell you...
I would be tempted to find out why the switch is malfunctioning. Is it a mechanical problem? Would a stronger spring keep the stand in place and prevent the switch cutting in?
I have just been through a similar thing on my bike, beefed the spring up and all is fine now. (The switch shouldn't cut the engine if travelling above 9mph anyway).
I think it is quite a useful feature to have, especially after I witnessed a fully laden touring bike pull out from a layby in front of me with his stand still down. Luckily I saw it, backed off and sure enough, come the next left hand corner he was bucked off.. *checks spelling*
i feel its best to get the switch working , but if ya really want to, let me know model etc, and i can spek to a bike mech mate of mikne who does electrics too.
If you remove the switch.
Try putting a bit of heavy rubber to extent the stand. If you leave the stand down and ride off as you turn it will hit the ground first and flick the stand up before the metal touches down.
My old VF750 had this and it saved me a couple of time
As Blues says, it is quite possible there are four wires because it is linked in with the clutch switch (in the same way as one switch on a two way light switch in your house has four wires). Ie the bike requires both the side stand to be up and the clutch to be in for it to start in gear.
I am unsure why it would have one pair of wires for down and one for up, I would expect it to be a simple connect/disconnect switch. Even if it has two separate connecting points along the switch's stroke, I would expect it to share an earth which would then only require three wires.
Funnily enough, Roachy and myself found ourselves at a little petrol station near Chester the other weekend (on a mercy mission) and were there for over an hour.
Whilst we were there a car and a motorbike turned up to fill the bike up. It turns out they were Germans who were touring the uk and one had hired the bike (a new gsx-r).
I had noticed that they'd been at the fuel pump for sometime but was preoccupied with other things. Anyway after being there for probably around twenty minutes, one of them came over and asked for my help. They couldn't get the bike to start and had tried "everything".
I wandered over and asked them to try and start it so I could watch and straight away made the comment "But your sidestand's down!"
The rider flicked up the sidestand and the bike started on the next stab of the button!!
We've all done it I guess lol!
Geoff, been there, done that. My first BMW K-bike had a mechanical connection, so that you could start in neutral on the sidestand, and when you pulled the clutch lever the sidestand flew up. The second replaced the mechanical link with a cut-out switch...you can guess the rest! Back to Cassie's bike: one wire, probably the black one, should go to earth. Should be fairly easy to trace. A lot of the Chinese bikes are older Japanese designs and should have the same wiring - should being the operative word! I don't mean based on Japanese designs, but often made with the origin Jap tooling with a licence from the original manufacturer. Of course, the terms of the licence mean that they can't be sold under the original name in western markets, so it has to be changed. But, to take an example, a Sukuda should be interchangeable with an older Suzuki. Might be an idea to put a post on one of the Chinese bike forums, there should be someone out there who knows exactly how it all goes together.
