Was up at Kinlochleven at the trials yesterday and hit a bit of heavy rain on the way up ,anyway pulled the bike out to wash it tonight and noticed the starter not working but bike fired when I pulled the clutch in .neutral light ok sidestand up on centre stand .Before I start fannying about with it could anyone point me in the right direction .Cheers :beerjug:
 
Neutral light is coming on in neutral and going out in gear Jeremy but like you say maybe thinks its in gear :beerjug:
 
Starter Relay
The big yellow one on the fuse box.

The neutral switch is working, you get neutral light:thumb2

The side stand switch switches the earth for the motronic relay.
Side stand up the earth comes direct from bike earth.
Side stand down the earth comes via the neutral switch.

Test
Ignition on
Kill switch off ( ready to start )
Bike in gear.
Side stand up
Does the moronic relay pull in ( fuel pump primes )
Side stand down
Bike in neutral
Does the moronic relay pull in ( fuel pump primes )

If this test works then the side stand switch is doing what it should, controlling the motronic.

You could have wiring fault. The starter relay has two paths for the earth to pull in the relay
1. Via clutch switch and seperate earth ( that path OK)
2. Via a diode inside the relay to the neutral switch earth.

Pull the relay, and check the base has 5 contacts showing. They should all be locked firmly into the plastic base. Check through a continuity test that socket 5 on the relay base which corresponds to where the relay blade 86b would connect is at earth potential when the bike is in neutral. If it isn't you have a wiring fault. If it is your relay is faulty.
 
Pump primes Ian ,My mates got a 1150 ill swap relays and check terminal connections let you Know. thanks again.:beerjug:
