Yamaha fazer runs but cuts out when clutch lever operated

[Neilr]

Hi
I have a yamaha fazer fzs 600 on a 03 plate, seems to have developed an electrical fault. The bike will only start when the clutch lever is pulled in and when released it cuts out straight away.
Second when running if put in gear it instantly cuts out, i suspect both fault are related. Any help would save me a major headache.

Thanks in advance.

have you tried to bypass the side stand switch to see if its related to that, sounds likely to me (im a bike noob but learning)

as i said im very new to this, but as i understand it, the clutch switch, side stand switch, and neutral switch all affect a bikes ability to start and run

from what you have said about it cutting out as soon as you put it into gear, it sounds like the bike is cutting out as it thinks the side stand is out

its only 2 wires so fairly easy to do, cheap to replace too

your first point about the clutch lever, is the gear selection/neutral showing up correctly ?

"The bike will only start when the clutch lever is pulled in" this would suggest the bike thinks your in gear so wont start because of this

Get a correct wiring diagram and post on here...

Hi
I have had to bypass the clutch switch to start the bike, not sure if bypassing the side stand switch will make a difference but worth a go?[/quote]

In that case you've done it wrong.

What have i done wrong? Can you please tell me as id love some guidance as to what direction to go in. Tried uploading a wiring diagram for my make and model of fazer but not sure why it wont upload.

Can you see the exact wiring diagram for your bike ?

If you can then you should be able to "see" where wires go and Thier colours, like the side stand switch, clutch switch, neutral switch etc. and determine if they are normally open for starting/running etc., Etc..

Are things like the clutch, stand and neutral switch "inhibitor" switches that prevent, for example, bike on side stand in neutral clutch out, the bike is in a condition that the starter will work and the engine will run, unlike, if on side stand and in gear with clutch out, it will not allow the starter to work or engine to run ( cos it will fall over ), or, if on stand and in gear and the clutch held in, it is allowed to start and run cos it won't fall over cos the clutch is held in ? Etc..

Yes the diagrams can be "spaghetti junction" until you know how to read them.

For your situation, ignorn the indicator circuit as that's not relevent, at the moment, etc..

Try and post the diagram again...

If that is the correct wiring diagram, print it off to A3 size, difficult to see on a small phone screen.
Also put bike on centre stand for safety.
