Neutral indicator light

(1/3) > >>

Hi
The neutral indicator light on my 400 has suddenly stopped working - the rest of the lights in the console are OK. I've changed the bulb but  that is the extent of my electrical skills .
Any guidance on where/what/how to check next would be appreciated.
Thanks

Ted go to the oil pressure switch, remove the wire and ground it to earth, light should come on.
If it does you need to look at the switch, if not look at all the connections.
Did you clean up the contacts on the bulb when you replaced it.

Regards,

Bryanj:
I think Paul means the neutral switch not the oil switch

How the bulb works is....It's supplied with 12v from the loom and the neutral switch supplies the 0V (when in neutral) to complete the circuit.
If the oil pressure lamp works, we can rule out the 12v side because it's works the same way.
This leaves the switch and the loom.
If you get a length of wire, attach one end to battery negative and use the other end to earth the neutral switch wire.  That should make the bulb light 💡 up.
The wire you're looking for is green with a red stripe.
Let me know how you get on.

Ted,

Further to the above it might be a bad loom plug.... it's that big plug behind the battery with yellows, red, green.... and the oil px / neutral switch feeds. If all else fails give this a check / clean.

Whilst it's apart, and as Paul & Mike suggested, stick a jumper wire into the red-green (upper connector) and the other end to any good earth... and the light should illum. (ignition on / bike in any gear)

Simon.
