Thanks Dragonworld, I adjusted the contacts a little, and now everything seems fine.
While I was "re-disabling" the side stand switch, I thought I would add in the diode to the neutral switch.
After some very dodgy soldering, and a burnt finger, everything was all wired up and ready to go. A quick test with the bike up on the rear stand, and everything's sweet. Until the test ride.
It works as it should, ie. starts with stand down in neutral only, and cuts off if put in gear. But the neutral light stays on all the time.
With the engine running, the neutral light is on all the time regardless of gear.
With engine stopped, the light is on in neutral and all gears except first. Weird
Could I have spliced into the wrong wire at the side stand switch end?
Or put the diode in backwards?
