What You’ll Need:

  • Pliers
  • Wire cutters
  • A screwdriver


First, locate the positive and negative terminals on your battery. You can do this by looking for the + and – symbols. Once you’ve found them, use your pliers to disconnect the cables from the terminals. Next, take your wire cutters and strip about half an inch of insulation off of each end of a piece of wire. Once that’s done, twist each end around its respective terminal (positive to positive, negative to negative). Make sure that the connections are tight so that there is no chance of them coming loose while the car is running.

Now, take the other end of the wire and touch it to the ignition switch. If everything is working properly, the engine should start right up! If not, you may need to fiddle with the connections a bit or try a different method altogether.

There are a few things to keep in mind if you find yourself in this situation. First, hotwiring your car will probably void any warranty that it may have had.

After finding these important things have a jumper cable and connect the positive terminal of the battery to positive site of ignition coil and vice versa. Doing this will power up the car and you’ll see power going to the dashboard.

Now to start the car you need to find the solenoid and then connect it with the positive terminal of the battery. After connecting it unplug the wiring of the ignition switch.

How Ignition Switch Works?

Ignition switch is an electrical switch which is used to start the engine by supplying power to the starter motor. It is usually located on the steering column or dashboard of the car. Ignition switch has three positions:

OFF: In this position, all accessories are turned off but battery is still supplied with power.

ACC: In this position, all accessories are turned on but engine cannot be started.

ON/START: This is the final position where ignition system and fuel system gets activated and engine can be started by turning the key further.

When you turn the key to ON/START position, a small amount of current flows from battery through starter solenoid coil which activates it. Starter solenoid is a large electromagnetic switch which when activated, supplies the high amount of current from battery to starter motor. Starter motor is a large electric motor which rotates the flywheel/engine crankshaft at a very high speed and starts the engine.

How Can Ignition Switch Go Bad?

Although ignition switch is made durable and can last very long, it is not indestructible. With time and usage, parts inside the switch can become loose or break which will cause problems in starting the engine. Also, moisture or water can enter into ignition switch assembly and corrode the electrical contacts which again causes intermittent or no power flow to starter solenoid coil.

In short, there are many reasons why an ignition switch may go bad but most common ones are:

  • Worn out internal parts
  • Water/moisture damage
  • Corroded electrical contacts

Bad ignition switches are one of the most common reasons for cars not starting. If you have a car with a bad ignition switch, then you might have asked yourself that how to start a car with a bad ignition switch. By following above mentioned methods you can start a car with a bad ignition switch.

Step Three: Disconnect The Wires

The next step is to disconnect the wires that are connected to the ignition switch. For this, you will need to use a wrench. Once the wires are disconnected, you can remove the old ignition switch.

Step Four: Install The New Ignition Switch

The next step is to install the new ignition switch in place of the old one. For this, you will need to use a screwdriver. Once the new ignition switch is in place, you can connect the wires back to it.

Step Five: Test The New Ignition Switch

The next step is to test the new ignition switch by starting the car. If the car starts, then you have successfully installed the new ignition switch. If not, then you will need to repeat the steps above until you are successful.

**Effective Strategies to Start a Car with a Faulty Ignition Switch**

Maintenance is an integral aspect of owning any asset, especially items frequently utilized such as automobiles.
