No neutral light

[Al Carter]

Has anyone lost their neutral light ?

I found my ECU loose and I think there was water on the wires too. I've had the plugs out of the ECU and made sure they are dry and no wires broken. I've removed the gear sensor and cleaned the crap off the inside face of it so it has good contact with the shaft.

Tuneboy reports the bike in gear, even in gear position 0. Gear numbers are being displayed correctly in Tuneboy but it just says in gear whatever is selected. Even neutral.

The Instrument LED lights up on self test when ignition is switched on.

Are Gear Position Sensors a known problem. If so I'll go and buy one.

Not a known problem that I'm aware of though I remember from way back that if you loosen the screws and push the switch as far to the right as it will go and retighten it, it should read accurately.

Thanks.

It helps.

I haven't heard of it being a problem either, have tried the reposition but I think this may prove to be a wiring fault due to riding in the wet all year.

Perhaps I should get a trailie for the bad weather and do what RocketSteve does and bag it up for winter......NOT !

I mean... I lost my temper with it yesterday, far too much throttle and got a phenomenal Bayliss type power slide going went sideways down a dual carriageway for a good 20 yards YEEHAAA 8) So I don't really mind the wet.

I found out what went wrong.


On the end of the gearchange shaft there is a spring loaded plunger which runs against the face of the gear position sensor.

Not a lot of lubricant gets up there. Some water had.

The spring had rusted, broken and the plunger was not making good contact against the sensor.

When it was in contact it had made quite a mess of the sensor contacts so I 'recontoured' the end of the steel plunger, found a good spring in my box of bits and it all now works.

NB
The plunger must have a point on it when new as this had worn a groove through all the flat-faced brass contact points on the sensor. I have filed it to a flat with a good spring behind it so it makes a decent connection. The ECU relies on that rusted spring to tell the bike which ignition map to use.

Did you take any pictures, perchance?
