Trick 1: Cutting The Wires
Bypassing a neutral safety switch sounds simple, but it can be dangerous and potentially illegal. Only attempt this if you have a legitimate reason to do so, such as testing the switch for a repair. Cutting the wires is one trick that some people use to bypass this safety feature.
Detailed Explanation Of How The Neutral Safety Switch Works
A neutral safety switch is designed to prevent you from starting your vehicle in gear by requiring that the shifter be in either neutral or park. When you turn the key, the switch sends a signal to the starter motor indicating that the coast is clear to engage, allowing the car to start.
Without the switch, the engine would start in any gear, which could be very dangerous.
Necessary Tools For Cutting The Wires
To cut and splice the wires, you will need:
- Wire cutters
- Wire strippers
- Electrical tape
- Butt connectors or wire nuts
Step-By-Step Guide On How To Cut And Splice The Wires
- Locate the neutral safety switch. It is typically located on the side of the transmission, where the shifter linkage connects.
- Use a wire stripper to remove the insulation from each side of the neutral safety switch wires. This will expose the unshielded wires.
- Use the wire cutters to cut the two wires from the switch.
- Use the wire stripper again to remove the insulation from the two ends of the cut wires. This will expose the unshielded wires on both ends.
- Twist the exposed wires together.
- Use a butt connector or wire nut to connect the twisted wires.
- Wrap electrical tape around the connection to secure the wires.
Safety Precautions To Take
Before you attempt to cut and splice the wires, it is crucial to take some safety precautions to protect yourself and your vehicle.
- Always work on your vehicle in a well-ventilated area.
- Always wear gloves and eye protection.
- Make sure that the vehicle is turned off and the key is out of the ignition before proceeding.
- Do not attempt to bypass the neutral safety switch unless you know what you are doing and have a legitimate reason to do so.
Remember, bypassing the neutral safety switch is dangerous and potentially illegal. Only attempt this if you have a legitimate reason to do so, such as testing the switch for a repair. If you are not sure what you are doing, it is best to leave this job to a professional mechanic.
Trick 2: Using A Jumper Wire
Driving with a faulty neutral safety switch can be frustrating, but there’s a simple trick for bypassing it. In the previous section, we introduced the concept of using a jumper wire to bypass the neutral safety switch. Here, we will look at what a jumper wire is, the necessary tools, and how to use it safely and effectively.
What A Jumper Wire Is And How It Works
A jumper wire is simply a thin and flexible insulated wire that is used to create a connection between two points in a circuit. When used to bypass the neutral safety switch, the jumper wire is connected between the ignition wire and the starter wire.
By doing so, the circuit is completed, allowing the ignition to start the engine even if the car is not in park or neutral.
Necessary Tools For Using A Jumper Wire
To use a jumper wire, you’ll need a few basic tools:
- A jumper wire: As mentioned above, this is a thin and flexible wire. It’s best to use a wire that’s long enough to reach the two ends of the connector safely.
- Wire stripper: This is used to remove the insulation from the end of the wire.
- Electrical tape: This is used to insulate the wires once the connection is made.
Step-By-Step Guide On How To Use A Jumper Wire To Bypass The Neutral Safety Switch
Using a jumper wire to bypass the neutral safety switch is a simple process. Here’s a step-by-step guide:
- Locate the neutral safety switch: This is usually located near the bottom of the steering column or on the transmission. It’s recognizable by its connector, which has two or more wires running into it.
- Identify the wires: Look for the two wires that lead to the connector. They’re usually the ignition wire and the starter wire.
- Strip the ends of the wire: Use the wire stripper to remove about 1/4 inch of insulation from the end of each wire.
- Connect the jumper wire: Insert one end of the jumper wire into the ignition wire connector and the other end into the starter wire connector.
- Test the connection: Turn the key to the “on” position. If you hear a clicking sound, the connection is successful, and the engine can be started.
Safety Precautions To Take
It is essential to take safety precautions when using a jumper wire to bypass the neutral safety switch. Here are some safety tips to keep in mind:
- Only use a jumper wire as a temporary solution until you can fix the neutral safety switch.
- Always disconnect the battery before working on any electrical system.
- Inspect the jumper wire for any signs of damage, such as frayed wires or exposed insulation.
- Use caution when working with electricity and always wear gloves.
By using the jumper wire trick, you’ll be able to bypass a faulty neutral safety switch and start your engine easily. Remember, this is only a temporary fix, and it’s crucial to have the switch replaced as soon as possible.
Trick 3: Testing The Neutral Safety Switch
If you are having trouble starting your car or motorcycle, the neutral safety switch is one area you should check. This component is responsible for ensuring that your vehicle only starts in neutral or park gear. However, like any other device, it can develop faults over time.
Trick 3 in this guide explains the steps to testing the neutral safety switch and what to do if it is faulty.
Why Testing The Neutral Safety Switch Is Important
The neutral safety switch plays a crucial role in preventing accidents caused by starting the engine in gear.
