Zx12r electrical
Can anyone help me out with a start problem on my zx12r -02. I can't start the engine when in gear, I guess I have wired the clutch switch wrong
but not sure. I'm i supposed to wire all three or just two of the cables going to the clutch.
Its a real problem when I have to stop and have 2nd or 3rd gear engaged and then the engine die, then I have to push the car just to get it to
neutral

The Starter Lockout Switch (clutch switch) should have two wires on the loom (R/G and LG)
At the connector, cut the LG wire and isolate this wire.
Link the R/G wire directly to Chassis.
The LG wire is still connected to the Neutral light and the ECU through other links in the loom.

Ok, thanks.
I have three wires going to the clutch switch on my loom, I have short cut two of them just to make it start, but it won't start when in gear.

If it won't start in gear then you must still have the neutral switch in the starter circuit.
Can you trace the wiring back to the original ZX12R loom?

I have the original wiring, just made some of the wires longer. I'll post a picture on the connector later to show you.
When I short cut all three the neutral indicator light is on all the time.

You should have it so that the ECU thinks the bike is in neutral all the time (but not your clocks/neutral switch) and that the clutch is permanently
pulled, and the side stand up. If you cant start when in gear, then you have not bypassed the neutral indicator light properly. Check the wiring
diagram again, and look to see how the neutral switch is powered/signals the ECU. I would study the diagrams again before making any more
modifications!

So, I finally sorted it out, did what you told me to, checked the wiring diagram again and followed the three cables to the clutch switch and noticed
i have connected the wrong cabels, should be black and black/red but i had connected the black and black/yellow at the switch.
Thanks for the help guys!
