The neutral switch does that job.

If the sidestand light works and the neutral light works but it still cuts out when put in gear, it sounds like there is a wiring fault. Your best bet is to work through a wiring diagram. There are also one or two diodes in the circuit. They generally don't die but everything's worth considering.

Thanks for your reply mate. found the switch behind the front sprocket cover. looks ok traced wires back to a plug under the seat, shorted out two of the wires and all works.. so looks like the switch at fault. apart from the obvious..will it be ok to leave the link in

Is it a small black plug with no wires connected to it? If so it is actually a diode for the safety circuit.

If it is the diode (like Africa Twins have) Wemoto sell new ones, although they confusingly refer to them as "rectifiers". There are 2 pin and 3 pin types available.

There's no such thing on dommies. And for a diode, it's stupidly expensive. Should be able to buy one for 0.02 - 0.05 pounds AT MOST.

The neutral switch is a bugger to replace or troubleshoot.

Not sure where they are on Dommies, they are very small and often hard to spot.

On AT RD04's they are on the wiring loom, on left hand frame rail, under the tank, so not easy to spot.

I had a faulty one on an AT (along with another in the fusebox) and it gave me a real runaround trying to suss out what was wrong.
