How To Bypass Starter Solenoid With Screwdriver (Step By Step Guide)
Before we plunge into the step-by-step guide, it’s essential to grasp the concept at hand. In our vehicles, the starter solenoid, which can sometimes turn into a bad starter solenoid, acts as a high-current switch to engage the starter motor.
When it malfunctions, it can leave us in a fix. That’s where this guide comes to your rescue!
To successfully bypass A starter solenoid using a screwdriver, follow these 2 simple steps outlined below:
- Step One: Locating The Starter Solenoid
- Step Two: Bypassing The Starter Solenoid
Step One: Locating The Starter Solenoid
Now that we’re all suited up for the task let’s first tackle the task of finding that elusive starter solenoid. It might feel like a game of hide and seek, but I assure you it’s simpler than you think, even in the expansive engine bay.
Identifying the Starter Solenoid
The first step is to locate and identify the starter solenoid. In most vehicles, it’s either on the starter motor or the vehicle’s fender.
Now, identifying it isn’t rocket science. You’re looking for a small cylinder with two heavy gauge wires connected to it. That’s your starter solenoid, also home to the starter gear!
Understanding the Wiring System
Once you’ve found the solenoid, it’s time to decipher the wiring. Those two wires you see, one comes from the car battery (main terminal), and the other goes to the starter motor (ignition terminal).
Recognizing these is critical as you’ll need to connect these two using a screwdriver to bypass the solenoid.
Step Two: Bypassing The Starter Solenoid
You’ve got your protective gear on, you’ve located the starter solenoid, and you’re ready for action! This is where the rubber meets the road – let’s dive into the bypassing process.
Safety Pre-check before bypassing a starter solenoid
Before we get down to business, let’s not forget safety. Ensure you’re wearing insulated gloves and safety goggles.
You might also want to have some jumper cables nearby in case you need them. The process may cause sparks, so it’s best to have your protective gear on!
Disconnecting the Battery
Next, disconnect the negative terminal of the battery. This is essential to prevent any accidental short circuits or sparks while bypassing the solenoid.
Identifying the Main and Ignition Terminals
As mentioned earlier, you need to identify the main and ignition terminals on the solenoid. The main terminal is connected to the battery, while the ignition terminal is connected to the starter motor.
These are also known as battery terminals. If you’re applying this process for a car that won’t start, I recommend our guide on how to start a car with a screwdriver, you’ll find more in-depth details and tips there.
The Bypass Process
Now, hold your screwdriver with an insulated handle, and touch the metal part of the screwdriver to both the main and ignition terminals.
This direct connection will bypass the solenoid and send power from the battery to the starter motor.
Reconnecting the Battery and Testing
Reconnect the battery and give the ignition a turn. If your vehicle starts, you’ve successfully bypassed the starter solenoid.

Post-Bypass Precautions You Must Consider
Okay, you’ve bypassed the starter solenoid successfully, and your vehicle is back to life. High fives! But remember, it’s not the end of the journey. Let’s delve into some post-bypass measures you must consider.
Safety Concerns
Remember, bypassing the starter solenoid is a temporary fix. It’s crucial to get the solenoid checked or replaced as soon as possible.
Continually bypassing the solenoid could lead to potential damage. This is especially important if your vehicle’s starter engages more frequently than usual.
Confirming Success
If your vehicle started post-bypass successfully, it’s a clear sign of a faulty starter solenoid. However, if it still doesn’t start, the problem could lie elsewhere.
It might be a battery issue or even a problem with the starter motor itself. In this case, a jumper wire might come in handy.
How To Overcome Common Issues During Starter Solenoid Bypass?
Did you run into a hiccup while bypassing the starter solenoid? No worries! Here’s a list of the most common issues you may face, along with some tried-and-tested solutions.
The Vehicle Still Won’t Start
We bypassed the solenoid, and yet, your vehicle won’t start. Frustrating, isn’t it? But hold on, don’t throw in the towel just yet.
There could be several reasons why a vehicle won’t start including the following:
- Checking the Wiring: If your vehicle still doesn’t start, check the wiring. Ensure there are no loose connections and the wires are in good condition. Make sure the pinion gear isn’t damaged either.
- Inspecting the Battery: A faulty or dead battery could be the issue. Check the battery voltage using a voltmeter. If the voltage is below 12.4V, your battery might need a recharge or replacement. This is when you can use the positive terminal to connect the charger. Sparking During The Bypass Process
Let’s talk about sparking during the bypass process and how to handle it safely.
- Understanding Why Sparks Happen: Sparks during the bypass process are normal due to the high current. However, excessive sparking could indicate a faulty connection or a short circuit.
- How to Safely Address Sparking: Wearing safety equipment is crucial. In case of excessive sparking, disconnect the battery immediately and check the connections. Ensure there’s no fuel leak nearby, as sparks can lead to a fire hazard.
What Tools Do I Need To Bypass A Starter Solenoid?
To bypass a starter solenoid, you essentially only need an insulated screwdriver which is one of the popular types of screwdriver used in many automotive applications.
However, to ensure safety and perform additional troubleshooting if required, it’s recommended to also have insulated gloves, safety goggles, a voltmeter for battery voltage inspection, and possibly some basic tools like pliers and a wrench to disconnect the battery.
What’s The Difference Between The Main And Ignition Terminals On The Starter Solenoid?
The main terminal and the ignition terminal on the starter solenoid are usually connected by heavy gauge wires.
The wire from the main terminal is directly connected to the battery, while the ignition terminal wire goes to the starter motor.
This distinction can help you identify the terminals. Also, the main terminal is typically larger and may have more than one wire connected to it.
Is It Possible To Permanently Damage A Vehicle By Bypassing The Starter Solenoid?
Bypassing the starter solenoid in itself should not cause any damage to your vehicle. However, it’s important to remember that this is a temporary fix, and continually bypassing the solenoid instead of fixing the underlying issue can eventually cause damage.
Therefore, if your vehicle starts successfully after the bypass, it’s a clear sign you should take it to a professional for a solenoid replacement or repair.
What Causes The Starter Solenoid To Fail In The First Place?
There can be several reasons for the failure of the starter solenoid. Most commonly, it’s due to wear and tear over time, which is unavoidable.
However, other reasons can include a weak battery, corroded or loose connections, or a faulty ignition switch. Regular vehicle maintenance can help to identify and rectify these issues early on.
Sparks During The Solenoid Bypass Process: Is It Normal?
Sparks during the solenoid bypass process are generally normal, as a high amount of current is being transferred directly from the battery to the starter motor when you connect the two terminals.
However, excessive sparking could be a sign of a potential short circuit or faulty connection. Always ensure you’re wearing protective gear and there’s no fuel leak nearby, as sparks could lead to a fire hazard.
Final Thoughts
We’ve journeyed through the step-by-step process of bypassing a starter solenoid with a screwdriver, and I hope this guide has been practical and easy to understand.
Remember, safety comes first! Bypassing the starter solenoid is only a temporary fix, and the actual issue must be addressed promptly.
So, the next time you’re in a fix with a stubborn starter solenoid, you know what to do! Stay tuned for more such practical guides.
