Hello, Can anyone identify this neutral switch. I bought it not really checking my existing one which the wires had snapped off. I have just been sorting through my parts and noticed the difference in length and it only has one wire. My bike is a 92 900ss. Cheers Gaz
It's from a later engine with a 3-phase alternator. They have different crankcases and the neutral switch earths through the crankcases. Your's is the shorter switch with 2 wires.
Off the following... I knew learning all the part catalogues would come in handy one day but it took a bit of typing!

Exige, Thank for your comprehensive reply, but I am still a bit unsure. I search all over for something that looked like the switch. I have also searched on the part number you posted and I get the picture below. It may be the case it does the same job but looks slightly different. I only wanted what bike it was on so I could re-list it on ebay so please don't go to any more trouble. Cheers Gaz
Could be a similar switch but for a different manufacturer as the connector is very much different to the Ducati one.
