If you’re looking for a kill switch wiring diagram for your Tecumseh engine, you’ve come to the right place. A kill switch is an essential safety feature on small engines like those found on lawn mowers, snow blowers, and other outdoor power equipment. In this article, we’ll discuss the wiring diagram for a Tecumseh engine kill switch and answer frequently asked questions.
What is a Kill Switch?
A kill switch is a safety device that is designed to shut off the engine in the event of an emergency. There are several types of kill switches, including manual push-button switches, automatic switches that activate when the rider falls off of a motorcycle or ATV, and mechanical switches that are activated by a pull cord on a boat engine. In the case of a Tecumseh engine, the kill switch is typically a manual switch that is connected to the engine’s ignition system.
How Does a Tecumseh Engine Kill Switch Work?
The Tecumseh engine kill switch is a simple device that interrupts the flow of electricity to the engine’s ignition system. When the switch is turned on, power flows through the switch to the ignition coil, which creates a spark that ignites the fuel in the engine’s combustion chamber. However, when the switch is turned off, the flow of electricity is interrupted, and the engine is shut down.
The kill switch is usually connected to the engine’s coil or magneto, which generates the spark that ignites the fuel. The kill switch interrupts the flow of electricity to the coil, which stops the spark and shuts down the engine.
Wiring Diagram for Tecumseh Engine Kill Switch
The wiring diagram for a Tecumseh engine kill switch is relatively simple. The switch is typically connected to the engine’s kill wire, which is the wire that runs from the ignition switch to the engine’s magneto or coil. When the switch is turned on, the kill wire is connected to ground, and the engine runs normally. However, when the switch is turned off, the kill wire is no longer connected to ground, and the engine shuts down.
Below is a table that shows the wiring diagram for a Tecumseh engine kill switch.

| Yellow | Kill Wire |
Frequently Asked Questions
What is the purpose of a kill switch on a Tecumseh engine?
The purpose of a kill switch on a Tecumseh engine is to shut down the engine in the event of an emergency. If the engine is running out of control, or if there is a safety issue, the kill switch can be used to quickly and easily shut down the engine.
How do I test the kill switch on my Tecumseh engine?
To test the kill switch on your Tecumseh engine, start by disconnecting the spark plug wire from the spark plug. Next, connect a test light or voltmeter to the kill wire and ground. Turn the ignition switch on, and then toggle the kill switch on and off. If the test light or voltmeter shows a change in voltage or continuity when the switch is toggled, then the kill switch is working properly.
Can a faulty kill switch cause an engine to run poorly?
Yes, a faulty kill switch can cause an engine to run poorly or not at all. If the kill switch is stuck in the “off” position, it will prevent the engine from starting. If the switch is stuck in the “on” position, the engine may run poorly or erratically.
Can I bypass the kill switch on my Tecumseh engine?
It is not recommended to bypass the kill switch on your Tecumseh engine. The kill switch is an important safety feature that is designed to protect you and your equipment. If you bypass the kill switch, you’ll be putting yourself and others at risk if there is an emergency.
What should I do if my Tecumseh engine won’t start?
If your Tecumseh engine won’t start, first check to see if the kill switch is in the “on” position. If it is, toggle it to the “off” position and try starting the engine again. If that doesn’t work, check to see if the spark plug is fouled or if there is a problem with the fuel system.
Conclusion
A kill switch is an important safety feature on Tecumseh engines and other small engines. By interrupting the flow of electricity to the engine’s ignition system, the kill switch can quickly and easily shut down the engine in the event of an emergency. By following the wiring diagram for your Tecumseh engine’s kill switch and performing regular maintenance, you can help ensure that your engine runs safely and reliably for years to come.
