A simple mechanism that sends out electrical current from the battery to the starter is known as the starter solenoid. A starter solenoid is an automotive relay being placed between a vehicle’s battery and its starter motor. A solenoid responds to a small electric current from the ignition system then switches a large electric current from the battery to the starter motor.

Every time the key is being turned, the solenoid engages. The solenoid uses an electrical motor in the starter to keep the car engine running. If it is not functioning properly, the vehicle may not start.

However, a solenoid is not always the root of the problem. Determining whether the cause of the issue is the solenoid, starter or to understand why your battery is not charging is important to save time and money by repairing it yourself or seeking someone for help.

When a faulty starter solenoid or a good solenoid does not get enough power from the battery, it fails to run a vehicle. How to jump a starter solenoid is important to know because it will work well for both testing the component and starting a vehicle even if it has a defective solenoid. So, let’s dig into the necessary steps to jump a solenoid and narrow down the causes that may make the car fail to start.

Installing solenoid may sound difficult to be done because sometimes it has a dangerous procedure which will cause a shock. Bear in mind that when a solenoid goes out, you can’t make your car start and typically, it will leave you stranded when ignored.  This is why you have to do it and you will get it done.


In jumping the starter solenoid, you will be turning the screwdriver or other metals employ into a manual switch. Be careful in performing the process for it can turn your body into the conduit as well. Always get the screwdriver off of the contacts soon enough or burn the starter motor out.

Bear in mind that this is a dangerous procedure, don’t do it unless you absolutely have to start the vehicle. Use a rubber-handled screwdriver and be careful in every step you take.

Step 1

Pop up the hood and find or locate the starter solenoid. The solenoid can be found in the fender well of the vehicle. This is something like near the battery.

Step 2

Get a screwdriver and touch the metal end of the post leading to the starter. It is opposite to the one that leads to the battery. Turn the screwdriver into a manual switch. It should bypass the solenoid in the process.

Step 3

Then drop the other end of the screwdriver down. To make it done well, you still need to touch the metal on the shaft of the solenoid to both terminals on the solenoid.  Have your assistant to turn the ignition in order to make the vehicle start at the same time. In doing this, you may notice a lot of sparks which could pass electrical current through your body. To avoid this, use a rubber-handled screwdriver and don’t touch the connection lengthily.

Step 4

Lastly, remove the screwdriver from the starter solenoid. Never left it on too long because it can arc the weld itself to both terminals and it will give a pretty bad effect on the process. At this step, the vehicle should be running without any interruptions. However, if it is not, do repeat the process again.

Going Deep with Starter Solenoid

A starter solenoid is the part of an automobile. The solenoid can be found above the starter motor. It changes a large electric current to the starter motor, in response to a small control current. In turn, the engine starts. The function of a solenoid is the same to that of a transistor. The only difference is that it is using an electromagnetic solenoid rather than semiconductor to perform the switching.

In case your starter solenoid is needed to be changed, buy a new one ensuring it will keep you up. You can look on Autofella.com for more tips and a wide variety of choices.

Exploring Alternatives: Options Beyond the Starter Solenoid in Car Engines

The starter solenoid is a critical component in a car’s ignition system, responsible for initiating the engine’s startup sequence by engaging the starter motor.

However, when the starter solenoid fails or malfunctions, it can render the vehicle unable to start, leaving drivers stranded and frustrated.

In such situations, exploring alternative solutions becomes essential to get the engine running again. This guide delves into the alternatives to the starter solenoid and their role in facilitating engine ignition and startup.

Manual Engine Cranking

One of the simplest alternatives to a malfunctioning starter solenoid is manual engine cranking. In vehicles with manual transmissions, drivers can attempt to start the engine by engaging the clutch, shifting into gear, and physically pushing or rolling the car to generate momentum.

Once the vehicle is moving at a sufficient speed, the driver can release the clutch to engage the engine, causing it to turn over and start. While manual engine cranking may require physical exertion and coordination, it can serve as a temporary solution in emergencies until the starter solenoid issue is resolved.

Jump Starting the Battery

Another alternative to a faulty starter solenoid is jump-starting the vehicle’s battery using jumper cables and a secondary power source, such as another vehicle or a portable jump starter. Jump starting bypasses the starter solenoid altogether by supplying external power directly to the battery, allowing the engine to be started using the vehicle’s ignition system.

To jump-start a car, drivers must connect the positive (+) and negative (-) terminals of the dead battery to the corresponding terminals of the power source, following proper safety precautions to avoid electrical hazards. Once connected, the power from the secondary source will energize the battery, enabling the engine to start normally.

Testing and Repairing the Solenoid

In some cases, the issue with the starter solenoid may be repairable rather than requiring a complete replacement. Before exploring alternative solutions, drivers can attempt to diagnose and troubleshoot the solenoid to identify any underlying issues, such as corroded electrical connections, worn-out components, or faulty wiring.

Using a multimeter or diagnostic tool, drivers can test the solenoid’s functionality by checking for continuity, voltage output, and proper engagement when the ignition key is turned. If the solenoid is found to be faulty, repairs may involve cleaning, lubricating, or replacing damaged parts to restore its operation

Installing a Remote Starter

For drivers seeking a long-term solution to starter solenoid issues, installing a remote starter system can provide added convenience and reliability. Remote starters allow drivers to start their vehicles remotely using a key fob or smartphone app, bypassing the need for manual key insertion and ignition engagement.

These systems typically include a control module, receiver unit, and wiring harness that integrate with the vehicle’s existing ignition system, enabling remote engine startup with the push of a button. While remote starters may require professional installation and programming, they offer an effective solution for starting the engine without relying on a malfunctioning starter solenoid.


While the starter solenoid plays a crucial role in initiating the engine startup sequence, there are several alternatives available to drivers when faced with solenoid-related issues.

From manual engine cranking and jump-starting the battery to testing and repairing the solenoid or installing a remote starter system, exploring alternative solutions can help drivers overcome temporary setbacks and get back on the road safely.

By understanding the various alternatives to the starter solenoid and their respective advantages and limitations, drivers can make informed decisions and effectively address ignition-related challenges in their vehicles.
