What Are Kill Switches?

Kill Switch

Kill switches are used in case of an emergency. They are safety mechanisms that are used to turn off a machine or components of the machine. They are only used when under normal conditions, the appliance can not be turned off. 

In the case of An ATV or Quad bike, the kill switch is used to turn off the vehicle’s engine. The rider can activate them by simply pulling or pushing the switch, or they can also be activated automatically in case the vehicle turns over or the rider falls off.



How Do Kill Switches Work?

Kill Switches work in two ways for an ATV. It can be either Normally Open “NO” or Normally Closed “NC.” The NO kill switch works in a way that grounds the primary ignition as soon as it’s pulled. The circuit is completed when the tether is pulled; therefore, a small short-circuiting takes place. This short-circuiting causes the engine to stop. 

In the case of an “NC” switch, the circuit is complete and is connected with the ignition system of the ATV. As soon as the Kill Switch is pulled, the circuit breaks immediately and thus restrict the ignition. This type of kill switch is used in battery-powered ATVs. 

How to wire a kill switch on ATV/quad bike?

The kill switch is usually mounted on the left handlebar of the quad bike. It can also be mounted on a clamp that is strictly used for kill switch purposes. Additionally, the switch must be placed in easy reach the place of the ATV. Keep in mind that its reach must not be hindered during the regular operation of the quad bike. 

Tighten the screws of the kill switch with a 3mm Allen wrench. Make sure the kill switch is not mounted properly. It shouldn’t be too tight or too loose. If you are an aggressive rider, make sure the switch doesn’t come off on its own, thus ruining your ride and causing inconvenience. 

As far as the wiring is concerned, almost all the kill switches are universal and will work against any ATV or Quad Bike. However, the wiring inside an ATV might differ from model to model; therefore, check out for the prominent landmarks. 

The kill switch comes with three wires. One of them would be short, and the other one should be the long wire. The third one will be the tether wire which is to pull to activate the kill switch. The short ones are usually connected to the ground whereas the long one is connected to the signal wire on the ATV engine. 

The installation of the kill switch varies from battery-powered ATV and Non-battery powered ATV. 

Battery Powered Quad Bike

In the case of a battery-powered ATV, the first step is to connect the short wire and ground it properly. It can be done anywhere on the frame of the Quad bike. You must make sure the paint of the quad bike is scrapped off of the area where the short wire is connected. In this way, the short wire will receive good ground. Any bolt will do the trick. 

The next step is to connect the long wire; it is a little tricky and might require some precision. To connect this wire first, you have to pull off the stator cover of the engine of your Quad bike. Once that’s done, you need to locate the pulse coil. If you’re not aware where is the pulse coil well, it is present next to the flywheel and has two wires that are coming out of it.

Next step, you would have to locate the signal wire of your Quad Bike. To find this wire, you must first remove the spark plug of your ATV and use a 12V Test Light. Before using the 12V test light, make sure both the key and run switch are on. Now, probe each wire with the 12V test light as you turn over the engine. When the light turns on, it means you have the correct wire with you. You have to connect the long wire from the kill switch and connect it with this signal wire. Make sure the connections are made properly; otherwise, the kill switch mechanism might not work. Also, turn off the power when connecting the cables; otherwise, the kill switch might blow up and not work in the future. Now reassemble the spark plug that you removed and then put the stator cover back to its initial position. 

The final step is to connect the tether cord to the kill switch body, and the installation is complete. To test it out, Properly start your quad bike and wait for a few seconds, Afterwards pull out the tether cord and activate the kill switch. The quad bike’s engine must die instantly, and if it doesn’t, it means the connections are not made correctly, and you have to start all over again. 

Non Battery Powered Quad Bike 

A kill switch can also be used installed in a non-battery-powered ATV. It’sIt’s installation is almost similar to that of a battery powered quad bike, such as the short wire must be appropriately grounded alongside the frame of the ATV where the paint has been scraped off. 

However, the attachment of the long wire is different in this case, and it has to be connected on either side of the handlebar ON/OFF switch present on the ATV. The long wire can also be connected to the positive terminal of the ignition coil. Hence the installation is complete now; connect the tether cord to the kill switch. Now the next step is to check whether the kill switch works or not. Properly start the Quad bike and wait for a few seconds. Now Pull out the tether cord and activate the mechanism of the switch you just installed. The engine of the quad bike must stop operating as soon as the cord is pulled. If this does not happen, it means you have not connected the wires properly and must do it all over again.
