Sv 650 speedo drive cable needed for 2000 model

[swifty09]

Does any one have one for sale maybe from an ex track bike or just one knocking about as mine has just started playing up

[andrewsmith]

Whats the drive doing?

[swifty09]

Was on ride home tonight and the speedo went from 70 on the motor way of corse to 0 the 50 to 0 the 60,70,60 then fixed it's self just lefties tank up to see if connectors are together which they are this has never happend before ?

[andrewsmith]

You need to clean the contacts on the connectors then test the drive to see if its at fault

[swifty09]

Do you mean the connectors under the tank for on the wheel sensor I presume it's a sensor any way :/

[yorkie_chris]

It's more likely the rotor breaking up than the cable. It has also been known for a loose battery connection or other wiring fault to cause the clocks to jump around.

[andrewsmith]

The wheel sensor is a hall effect sensor, so if it goes wrong it would be broken circuit or a fully closed circuit sending a constant voltage.

The connector is under the tank and is a clear/ white under the air box near the headstock

[swifty09]

Ye I seen that conector and checked it was clipped together will see how it goes on the way to work in the morning thanks for the help

Have you had the front wheel off for any reason recently?If so id suspect the rotor got damaged when putting the wheel back on.Common problem.

[swifty09]

No not touched the front wheel is there a main dealer to price up new part just incase

[yorkie_chris]

About £15 for the rotor.
I have never seen a broken sensor (£100+), but loads of rotors.

Only thing I've seen other than rotors, and wiring faults making both speed and tacho jump about, was when wire for sensor had been squashed in lockstop.

Do the blades go in the sensor on the wheel not had my sv that long not to clued up on them cheers for the help Chris if so were can I buy one if I need it

[yorkie_chris]

There is a drum which runs within the sensor, and 4 tangs which are driven by the wheel, these end up snapping off.

I may have a drive rotor in the house if it is that is the case.
I'll check the state of mine at the weekend

[swifty09]

Ok just got home checked battery and negative was tightend more took her for a run was working at first went over a speed bump and it stopped and went over the second it start again ride all the way home was fine any ideas with the extra info

[yorkie_chris]

Check under green cover under right infill panel, 2 fat live wires go into it, give them a wiggle check they aren't loose.

If they aren't hanging loose then I'd pull front wheel off.

[swifty09]

Blades are broke 2 of them any ideas were I can get then from any one
