Default Problem finding neutral

Hi guys,

Bike is a 2005 F4 1000s with 6k miles on it.

Started to see some problems with the neutral light flickering on/off when bike warm and putting it in neutral whilst waiting at stop lights etc. Bike is defo in neutral, but the light flickers on/off. Sometimes rocking the bike a bit sorts it out. Sometimes the light doesn't even come on at all. Bulb is fine, lights up when turning ignition on from cold.

Other day, went to start it from cold, and it wasn't finding the neutral light. I was cycling through 1st, neutral, 2nd, back to neutral, back to 1st, did this maybe 8 times and it woudn't find the light and wouldn't start. Finally I moved the bike a bit and I was able to find the light eventually.

This will be annoying if it continues, so what do you guys think is wrong? Anything quick and easy I can check? Bike has been fully serviced about 300km ago, and was working fine since, this problem started about 100km back and has been getting slowly worse on each subsequent ride.

thanks for your help

There's a bullet connector that routes round the back of the engine, between it and the swingarm for the Neutral light - I had the same issue on my 750 - the connector had become loose, pushed it back together and it fixed the issue on mine.

The reason it wouldnt start is cause I'm guessing the sidestand was down, and / or the clutch was out.

I'm sure its a light green wire on mine - if not i'm sure someone will correct me.

I had a play with the battery and pulled on all the wires, didn't change anything. I sat on the bike and cycled through 1/N/2 and even rode it a tiny bit to get the gears moving, and it was finding neutral fine every time. Could this be neutral sensor if it's sproadically going wrong?

I didnt see this till this morning - I'll see if I can get a shot of its location this evening - apologies if i've read your post wrong, but the bullet connector isnt near the battery, mine sits pretty much behind the RHS footrest hanger.

If thats not your issue, i'm afraid I'm not sure on the possibility of the sensor itself failing - I'm sure Donsy, Joe, or one of the other guys who had had theirs stripped a number of times will be able to advise on that though.

Wink neutered neutral?

more than likely the bullet connector is loose/corroded

it is a grounding switch...disconnect the bullet connector
put a paper clip or wire in the harness side, touch it to the motor (key on) you should have a bright neutral light
check the switch with an Ohm meter....in neutral it should show good continuity ground, less than an Ohm......they do fail

double check the switch.....because to change it, you WILL be standing on your head

if you had an EU-3 Brutale......you'd have to pull the cat too
and if you had the welded in cat also......you'd set fire to it.....

less trouble

Your neutral switch is sticking remove it apply wd40 and wiggle and free up the switch. Or buy a new switch from ducati part no.53940201A cheaper.

Mine does the same when it's cold out but I just live with it. Once the engine warms up it goes away. I'll be doing an oil change soon with Amsoil and hope to spend less time fiddling with the shifter at lights.

Hey guys, thanks for the advice above, think I need to change the battery out (believe it's on the orig Yuasa, it's a 2005) so will do that and check the bullet at the same time and see how I go with the problem.
