Sidestand Light

Message

yellowasp · #1 Post by **yellowasp** » Sun Dec 27, 2009 9:03 pm

The light on the dash indicating the sidestand is down is perminatly on , even when the sidestand is up. Goes into gear OK and rides as normal but the light remains on. Happened today while out training.

Any ideas where to look ?

Oh and belated Xmas wishes everyone and a happy new year

It sounds like what happened to mine. If you still have the old plastic switch, the pin may have broken, so that it isn't turning the switch as it should. For some reason mine left the light on but allowed me to run the bike OK. Can't think why as should do both light and cut off together. I ain't got much time as just about to go on hols, take the switch cover off and check the pin. I managed a temp, repair job on mine with a short screw replacing the pin, but eventually died, so I fitted the newer steel pin switch, well worth it as much better.
Hope you sort it , gotta go now, good luck.

a short length of bike spoke is an ideal replacement - drill into the old plastic lug point to fit it

Thanks chaps, I'll look at that when the snow has thawed off it

Hi Yellowasp ..... If I were you, I'd try a different tack when the snow thaws.

It won't be a broken pin on the sidestand switch for 2 reasons:

1) The bike is starting OK - therefore the switch is working.
2) Your bike is a later model that has a sidestand switch with a metal pin (not the fragile plastic type)

There are actually 2 distinct circuits that are controlled by the sidestand switch - one is the warning light, the other is the interlock that stops the engine running if it's in gear with the sidestand down.

I suspect you have a wiring fault in the warning light circuit - or, less likely, the a problem with the part of the switch that controls this circuit.

Agreed, the yellow ones should have the metal pin.

I had a the metal tracks in the rotary switch pack up on one of mine.

If you don't mind losing the cut out functionality you can ditch the switch and connect the outside two wires at the harness connector.

LOL - It's a bronze one .... which certainly has a metal pin ....

OK - update - I've had a look at the wiring diagram:

I think we can rule out the switch itself - it's a change-over switch so very unlikely that if it's starting and running OK the switch is at fault.

The lamp in the instrument pack is illuminated by pin 13 of the instrument pack being grounded.
Pin 13 of the instrument pack is connected to the sidestand switch via a Brown/Black wire that runs to a connector (I expect this connector is close to the sidestand switch) and from the other side of this connector, via a Green wire that then runs to the centre terminal of the sidestand switch.
When the sidestand is UP, the centre terminal of the sidestand switch is open circuit - the lamp should be off.
When the sidestand is DOWN, the centre terminal of the sidestand switch is connected through the switch to ground (via the black wire that connects to one of the outer terminals.

The problem you have is that the connection to the sidestand lamp is being grounded "by other means".
In other words, somewhere between pin 13 of the instrument pack and the centre terminal of the switch, the brown/black wire or the green wire that it connects to is shorting to ground.
Somewhere along these wires you will find that the insulation has been cut or worn away and the conductor is touching an earth (probably the frame or engine but maybe an earth wire that has lost its insulation at the same point.

Find the location of the problem and re-insulate.

Hope this helps.

Out training for what?

Thanks D-Rider, I will have a look at that when I get chance

as andy says, theres a couple of places behind the nose fairing where the loom feeds through brackets bolted to the frame. i noticed the loom was tight at these pionts when i took my fairing off.

Don't disagree with any of the above, but I would still check the rotary switch and pin first and check all is intact, it is only a 5 min job, (unless you have a belly pan, which will need to be dropped down for easier access). I would certainly not bet anything on Aprilia having not fitted an old type plastic pinned rotary switch unit on a 2002 model.
When my plastic pinned 2001 version broke it did exactly what yours is doing, with the warning light on and still running OK, (cut out not activated with the light).
If OK then check the loom as suggested.
Good Luck either way.

aye , mine has a belly pan so will check that first as i am doing oil and filter change this weekend . D Rider , do you know anywhere around Cov that change a supplied rear tyre without stealing my wallet ? 25 pounds they want

OK places I've been for tyres are:

Robsom Racing

#B Brailes Industrial Estate, Brailes Road, Shipston on Stour, Warwickshire CV36 5AD
Tel: 01608-664122

It's a bit of a way from Cov but Mike is usually pretty competitive for tyres and fitting .... and a nice chap too.

Bikers World @ Daventry

2 Browns Road
Daventry
Northamptonshire
NN11 4NS
Tel : 01327 312 724
http://www.bikersworldshops.co.uk/uk/shops/daventry/

Bikers World also have a place in Birmingham - consensus is the staff at Daventry are good and helpful ... in marked contrast to those at Birmingham

... and one I've never used so far but many of those on the Coventry Bikers Forum strongly recommend:

James (Burgerbiter on the forum)

He's somewhere off the A45 near Wing Wah
He can be contacted on this number: 07786071898
I've not met him but I'm pretty sure that he'll know how you found him if you mention D-Rider put you in touch.
He used to have an 02 RSVR BTW.

Not sure how keen Robsom Racing and Bikers World are at changing a supplied tyre (probably OK) but I know that James will definitely do it.
Hope this helps

Bikers World was one who wanted £25 to do it. I will try James as he as the same name as me so can't be all bad

Thanks again for all your help
