The sv's cutoff circuit, sequence,testing & what it stops the bike doing.

[muzikill]

Can anyone go through this. What each switch/sensor will stop it doing. What to check etc....

I know it has the following and i think it would be useful as a collective topic to understand this and fault find. My current sv wont start but the fuel pump primes and the starter turns the engine over. I dont know yet if it's being starved of fuel or it wont spark.

Im not sure if this them all or in circuit sequence.....

Sidestand switch (above the sidestand, green connector under the seat)
Clutch switch (at the left handlebar lever)
Tip over sensor (under the seat beside the battery/fusebox)
Emergency cut off (red switch on the right handlebar)

In the short term these two:

If the clutch switch were the problem it wouldn't turn over.
If the engine stop switch were the problem it wouldn't prime the fuel pump.

I'll be back later when I've looked at a wiring diagram to see if there's anything obvious that could account for your problem. In the first place I'd look at everything electrical - I suspect something isn't connected correctly/at all.

ta bud im about to put it in dealer mode to check it out for a fault code.

Try checking the main indicator relay, I had a similar problem a while ago - the fuse was corroded due to water ingress, causing it to short out. Check the relay fuse - it's under the pillion seat.

If pump primes and starter turns motor none of switches you listed are problem. Sounds like you have no spark.

My mistake the pump doesnt prime,when the key is turned the throttle valves do their calibration.

Ive tested these areas so far last night.

Signal relay faulty, (indicators go fast instead of 'normal', also i did find it also a relay+diode for the side stand)
Fuel pump relay working, (12v connected/disconnected and it closes/open)
Sidestand switch working, (connector check for open/closed continuity when moving it up and down to connect/disconnect switch)
Clutch switch working (The starter motor turns the engine over)

The big one! - The tip over sensor is faulty (c23 error), there is no resistance between the two pins at either end on the sensor when its disconnected and tested for 'ohms'. Funny thing is dealer mode didnt pick it up! - all dealer mode did was go into the tps adjustment mode with no codes!

Hopefully this will solve it and fingers crossed it aint the fuel pump. now i have to source a sensor. It seems that leaving a bike sitting around for 2+ years allows the electrical gremlins to get in

btw can i test the fuel pump works/start her, without the tip over sensor?
Can i test for voltage at the tip over sensor plug / fuel pump plug? - i suppose the tip over sensor would have to be working to allow the power to go to the fuel pump to prime it therefore stopping me from testing it fully (ahh, i could do a continuity test somehow!)
