Clutch Switch?

[neodude112320]

I'm toying with an idea for an Arduino based immobiliser system for my GS as it's parked at a train station for 8 hours a day, every day.  While I have the circuit working , I need it to stop the bike from starting, though once the bike is started it will shut off (So no hooking it straight up to the ignition).

I was wondering besides stopping the bike from starting when the clutch isn't engaged, does the clutch switch serve any other purpose?

Not that I can think of. Mine had a mangled wire causing occasional starting issues. I disabled it by just pluging  the two wires together behind the headlight as one is a male and the other female. So you could wire a hidden switch based off that that should serve your purpose. If I'm thinking correctly all you would need is 12V toggle or momentary that's sealed against the elements and could be hidden. Maybe behind the headlight or under a fairing. Unless I completly misunderstood you. Let me know how it goes

If you're going to try an electronic solution to a killswitch, you need a relay (either coil-type or solid-state) and you can either hook it into the clutch switch or the kickstand switch (neither of these does anything but make sure the bike can't start under certain conditions).

I kinda like the kickstand switch, because you could hide your electronics in a small waterproof case and hide it down under the frame or such and not worry. You would be able to start the bike in neutral but once it's in gear it'll shut off if the relay isn't closed, whereas the clutch switch is constantly being toggled anyway and if you manage to start the bike, it won't shut it off even if the relay is open.

Just my $0.02, and let us know how this project goes!

Thanks for the reply guys.

Yeah I've got the circuit done, software programmed and it works well (To fire a relay) i'm just going to do some testing tommorow and wondering the best place to run it to.

I Do like that kickstand switch idea, I'll give it a whirl and see how it goes.

Basic run down of the immobiliser:

Rather than having to carry around a remote OR have a hidden button somewhere. When the ignition is switched on, the immobiliser will wait for a specific set of inputs before it fires a relay. In this case being the Front brake switch and the rear brake switch, so to start the bike you would have to tap the front brakes and the rear brakes a certain number of times before the relay would fire (Really any button/switch could be adapted for this).

I'm also thinking of adding the following features:

-If it's guessed incorrectly (say three times) it will trigger the horn as an alarm (For a set period of time or unless reset)
-If it takes too long to input the code (a minute maybe) it will also trigger the horn

At this stage it's all in testing

Sounds pretty cool, what i'm going on about would be more of a interlock. That's way more than I'd need. I'd make money on insurance if someone ran off with mine. But it's a sound idea for having it sit at a station unattended, unless they just throw it in a truck and go.

[neodude112320]

Yeah that's right, I'm aiming for an immobiliser, It will also save me on insurance well. No matter what kind of immobiliser I use anyone could just throw it into the back of a ute/truck and take off with it anyway. Luckily where it's parked it would be a bit hard to get to (Poles in the way) plus there are quite a number of security cameras.

I'll post my results, schematics and coding if anyone else may want to build one.

Yeah, start a thread with the how-to's. All information is good information in this area.
