secondary kill switch for clone?

[Gator]

allright i have some pics to help

The first pic is the wire you want to use, its the yellow one coming from the square box. This wire from the factory runs down to the oil sensor probe that is screwed into the block below it, it has a male/female quick connect rite between the oil box and oil probe on the yellow wire, if this wire coming out of the box touches a ground it will kill the engine.

pic 2 is a close shot showing the box and wire.


pic 3 is the wire not to use, just let it hang or tape it up once the wires are seperated at the male/female connector, this is the wire coming from the oil sensor probe that screws into the block.

pic 4 is the horn button, behind the button is a place for 2 wires, one runs from the button to a ground, the other runs to the yellow wire coming out of the square oil sensor box.

simple and reliable, both my karts are done like this. And the low oil sensor will not and can not shut the engine down due to low oil or ruff terrain because the oil sencing probe is not hooked up. you can simply tap the button and shut the engine down now.

Very good- The only "complaint" I have about that is that if you use a momentary pushbutton (like a horn button, doorbell, etc), you must hold the button down until the engine completely stops rotating, or it will fire right back up again. This has the potential to create a bit of a hairy situation if you're out of control and need to shut down.

I very strongly recommend you use an actual switch or latching pushbutton- once you hit it, it's off, and you can keep your hands on the wheel where they need to be in a crisis.

Absolutely!!!
2 switches should always be present.
1 at the steering yolk and 1 on the engine(s) themselves.

not correct, like i stated earlier, all you have to do is simply tap the button, not even push it, i mean you can tap it with your finger and the engine will die, no holding the button down, using the oil sensor like i did. This is one reason i like using this method for my 7yo daughters kart, its alot easier for her to tap a button than find a toggle in an emergency situation.

Once the sensor has a ground thrown to it, via a switch or push button, the engine will immediately die and will not refire when the button is released like in the case if you had a push button wired to the factory kill switch bc all that is doing is grounding out the coil, and it could refire, if eng is still spinning

Think about what is being done here for a min. Im utilizing the factory low oil sensor switch, when all hooked up from the factory straight out of the box, when the oil is low or not present to the oil sensor probe in the block, it throws a ground to the yellow wire and the engine dies, it dosent restart even when the engine is still spinning from being shut down, that would ruin the engine if it were out of oil.

It is designed like this to save the engine if it is low on oil.

This is why you must bypass or unhook the oil sensor probe when used on a kart, if you hit a bump and oil isnt near the sensor probe, a ground is thrown to the yellow wire inside the box, engine dies and wont restart untill engine has completely stopped spinning, and restarted with the rope.

if you are splicing into the factory red kill switch, then yes please use a toggle style switch, a push button is not safe used this way, and could refire like the guys stated above., if the button is released before the engine stops spinning.

I see it, now. Interesting- not too sure I'd want to rely on it, though. Personally, I'd rather a "hard" switch wired right to the coil. Simple, straightforward, and about as "guaranteed" as it gets.

Points for creativity though, Gator!

Gator- great tip, I just tried it out on my bike, I had rigged up a kill switch to test, and it worked just as u said. No sputtering just dead at a tap of the switch. Good thing about this method is that it can be a one wire setup, u can use the frame as the ground.
