I need some help. Does anyone know what this is/what happens when its not connected?

My manual doesnt have any diagrams of the cables so I can't figure it out that way and I can't find anything browsing the Ducati forums. I would of course just reconnect it, but I bent my handle bars and it cant reach its connector anymore.

Sorry about the potato phone pictures.

Have you tried searching for your models wiring diagrams?

Educated guess - switch to ensure that the clutch is depressed when trying to start the bike?

Where does the other end of the cable come from?

No, that would make too much sense.

I just stepped out and it starts up either way, and I can only assume that the circuit would be open since its disconnected, so I'm not totally sure about that. Maybe I'll rig it closed somehow tomorrow and see whats different.

It disappeared into a cluster of wires that's ziptied too tight to tug it through. I tried to read the writing on the cable and match it up, but its worn off over the last 11 years. I'll try some more tomorrow when theres light again.

It's either a position sensor/switch or a fluid sensor/switch. Since it's on the left side, I'm leaning towards position sensor/switch. If the bike is fuel injected, then maybe the switch just affects the fuel mapping. Or, maybe it does affect the starter but is set up so you can remove it. I know of a few kickstand kill switches that work that way because it's better to fail in a way where the bike is operable than inoperable.

Try starting the bike in gear with the clutch pulled and with it released (holding the brakes of course). Clutch kill switches usually only come into play with the bike in gear.

Both the starter and my idle have been a little off since since it came off. I was wondering if it affected my fuel map as well. I can cheat and just remap my power commander box, but thats sticking a bandaid on a bigger problem. I'd love to take it to a shop, but I get kicked out as soon as I mention the word "Ducati".

Clutch microswitch.

Prevents the bike from being started in-gear, in conjunction with the neutral signal switch. (may not need the clutch engaged if starting in neutral)

It may also provide a clutch signal for the ECU if the bike is fuel injected, so that the bike can control fuel flow more precisely when shifting, or any other time the clutch lever is pulled.

It likely joins the main harness behind the headlight, and probably isn't longer than it needs to be. It may or may not be detachable from the main harness, if the main harness was used on various bikes with different handle bar control heights, or as a damage-repair replaceable part.

This explains so many of my problems. Thank you very much my good sir.

Glad to help.

And I am kind of a Ducati fan myself. I've not yet had the pleasure, but I have wanted a 900SS/CR for a while.

Have you considered that it might be a, "Don't blow the bike up in a ball of fire," switch?

It's a blast, but as with all things there are pros and cons. Just to list a couple,

Pros:

You get to tell people you have a Ducati

You have all the power you will ever reasonably need

Cons:

Everyone thinks the sound of my dry clutch means its broken

No shop in town will touch it and the nearest dealer is 90 miles away

It runs a high risk of going Italian on you and its rather temperamental about things.

People judge you because you ride a Ducati

But seriously, get one someday. Just don't do what I did and lay it down doing the lamest thing imaginable.

It wouldn't be the first time its attempted to go all Italian on me. It leaks fuel anytime its on its side, and when I say leaks I mean fuel flows freely out of it. You can imagine how fast I killed the engine after I laid it down.

I haven't read the manual, but I'm going to go out on a limb and guess that leaking fuel like that isn't normal.

It's definitely on my list of things to do. For now I'm just trying to keep it as upright as possible.
