Curvy starter not turning. - Page 2 - SV650.org

Right I've tried testing the voltage and there is nothing on the green/yellow wire. However, can one of you give me a complete dummy/laymans guide to EXACTLY what I should be testing between as my electronics knowledge is pretty much non existent and I wouldn't be surprised if I had managed to balls it up. Apologies for being a complete dullard electrics is just not my area of expertise!!

Test green/yellow where it exits kill switch assembly.

This list relies on there being no other electrical problems - clearly if all the electrics are dead it would be a waste of time investigating the starter system as something more fundamental is faulty, which obviously will cause the starter not to turn but not because there's a problem with the starter.
This is a complete listing of all tests on the solenoid supply, clearly one may dispense with some of them if tests made further along the circuit have already been made and proven good, but for clarity they have all been added to this list.

All tests done with ignition on, in neutral, clutch pulled. All connectors assembled and intact unless stated.

1. Remove the starter cutout relay, is the orange/white wire connector live?
Yes; go to 2.
No; fault lies in fuse 3 and/or wiring from there to relay base.

2. Refit relay, backprobe orange/black wire on relay base, live?
Yes; go to 3
No; fault in relay and/or connections.

3. Remove the right switchgear connector, is the orange/black wire on the loom side live?
Yes; go to 4.
No; orange/black wire in loom from relay to right switchgear connector broken. See switchgear tests below.

All further tests require the starter button to be pressed when testing.

4. Reconnect right switchgear, backprobe yellow/black wire on loom side of connector, live?
Yes; go to 5.
No; fault is inside switchgear, connector or wiring from connector to switchgear. See switchgear tests below.

5. At left switchgear connector is the yellow/black wire live?
Yes; go to 6.
No; yellow/black wire between left and right switchgear connectors on loom broken.

6. At clutch switch test for voltage at both wires, which are the same colour, one should be live.
Yes; go to 7.
No; left switchgear connector/wiring broken.

7. At left switchgear connector loom side backprobe yellow/green wire, live?
Yes; Go to 8.
No; left switchgear connector/wiring broken.

8. At solenoid backprobe yellow/green wire, live?
Yes; go to 9.
No; yellow/green wire/connectors from left switchgear to solenoid connector broken.

9. Check continuity from black/white wire on solenoid connector to battery negative.
Yes; faulty solenoid.
No; broken black/white wire.

Switchgear tests:

Remove right switchgear connector, remove right switchgear. Identify stop/run switch and starter button connections in switchgear.

1. Check for continuity between switchgear connector orange/black wire and same on stop/run switch.
Yes; go to 2.
No; orange/black wire and/or connectors broken.

2. With stop/run switch at 'run', check for continuity at switch connections - orange/black connection to orange/white connection.
Yes; go to 3.
No; stop/run switch faulty.

3. Check for continuity between orange/white wire on stop/run switch and same on starter button.
Yes; go to 4.
No; orange/white wire and/or connections broken.

4. With starter button pressed check for continuity at switch connections - orange/white connection to yellow/green connection.
Yes; go to 5.
No; starter button faulty.

5. Check for continuity between yellow/green wire on starter button and same at switchgear connector.
Yes; good!
No; yellow/green wire and/or connections broken.

Useful - me?

How very dare you! I ain't ever been useful and I ain't about to start now!

Sid, thank you so much for this was really helpful. If our paths should cross the beer will be on me.

it appears that i have a faulty started button!
