Recently my neutral light stopped working. The light is good because when I turn the ignition on the neutral light comes on. once started I can put the transmission in neutral but the light does not come on. When in neutral I can put down the kickstand and the stand switch will kill the motor.

I thought it was the neutral switch so I replaced it and I'm still having the same issue. If you look at the wiring diagram (Pg 7) there is one other component hooked to the wire from the neutral switch to the instrument panel. It is the (5) Safety CPU. Looking at the diagram it doesn't look like this would have any effect on the neutral switch but I'm not sure.

Any help would be appreciated.

Can't help but I'm curious as to what the forum experts think. My Brutale 910 neutral light comes on when I switch the ignition on no problem but when I hop on the bike and put it into gear it takes a moment to go out, maybe half a second but there is a noticeable delay.

I'm off to work now, but will go through drawings tonight, those relays are often interchangeable with others on the bike which is great for testing.
Have you got a tester to make sure the neutral sw is working, it's very easy to break the tip off @mdwheeler.

Donsy,
Yes I have a tester I will pull the switch and test it. I will get back with you.
The "N" switch makes an earth connection when the gearbox goes into neutral, so don't go through all the hassle of removing the switch again, just test it while it's in place.

Donsy is correct the neutral switch just grounds the light, lighting it
separate the bullet connector with your DDM set on Ohms you should see continuity to ground with the bike in neutral
on the harness side, with the bike running you should see system voltage between the harness and ground
My vote is you have a corrosion problem between the bullet connector and the dash......

I use dielectric grease...... I'm 3 blocks from the Pacific Ocean

:wink2:

I tested the switch and it was fine. I pulled the switch and cleaned the male and female connectors. Put some dielectric on and closed the female connector a little. I reinstalled the switch and it is working fine. It seems that the connector was just not making good connection.

I should have cleaned the female connector when I installed the new switch.

Thanks for all the help.
