Checking your car starter is an important part of maintaining your vehicle. The starter is responsible for starting your engine, and if it fails, you won’t be able to drive your car. There are a few simple steps you can take to check your car starter and make sure it’s working properly.
The starter is located on the side of the engine, and it’s usually connected to the battery by a thick cable. To check the starter, you’ll need to disconnect the battery cable and then use a multimeter to test the starter’s voltage. If the voltage is below 12 volts, the starter may need to be replaced.
In addition to checking the voltage, you can also check the starter’s connections. Make sure the connections are clean and tight, and that there’s no corrosion on the terminals. If the connections are loose or corroded, the starter may not be able to get the power it needs to start the engine.
1. Voltage
Voltage is a key factor in checking a car starter. The starter motor is an electric motor that uses the car’s battery to turn the engine over and start it. The voltage of the battery is what provides the power to the starter motor, and if the voltage is too low, the starter motor will not be able to turn the engine over.
- Battery voltage: The voltage of the battery should be between 12 and 13 volts. If the voltage is below 12 volts, the battery may need to be replaced.
- Starter motor voltage: The voltage at the starter motor should be the same as the voltage of the battery. If the voltage at the starter motor is lower than the voltage of the battery, there may be a problem with the wiring or connections.
- Voltage drop: When the starter motor is engaged, there will be a voltage drop across the starter motor. This voltage drop is caused by the resistance of the starter motor windings and the connections. The voltage drop should be no more than 2 volts.
- Voltage spikes: When the starter motor is disengaged, there may be a voltage spike. This voltage spike is caused by the collapse of the magnetic field in the starter motor. The voltage spike can damage the starter motor or other electrical components.
By understanding the role of voltage in checking a car starter, you can help ensure that your car starts every time you turn the key.
2. Connections
When checking a car starter, it is important to inspect the connections. Loose or corroded connections can prevent the starter from getting the power it needs to start the engine. There are a few key connections to check:
- Battery terminals: The battery terminals should be clean and tight. Loose or corroded battery terminals can prevent the starter from getting the power it needs to start the engine.
- Starter motor terminals: The starter motor terminals should also be clean and tight. Loose or corroded starter motor terminals can prevent the starter from getting the power it needs to start the engine.
- Ground connection: The starter motor is grounded to the chassis of the car. The ground connection should be clean and tight. A loose or corroded ground connection can prevent the starter from getting the power it needs to start the engine.
By checking the connections, you can help ensure that your car starter is getting the power it needs to start the engine.
3. Solenoid
A solenoid is an essential component of a car starter. It is an electromagnetic switch that uses electrical energy to create a magnetic field, which in turn engages the starter motor with the flywheel. When the ignition key is turned, the solenoid receives an electrical signal from the battery and uses it to create a magnetic field. This magnetic field pulls in a plunger, which engages the starter motor with the flywheel. The starter motor then turns the engine over, starting the car.
- Construction and Operation: Solenoids typically consist of a coil of wire wrapped around a metal core. When an electric current passes through the coil, it creates a magnetic field that pulls the plunger into the solenoid. This action closes the contacts, allowing current to flow to the starter motor.
- Testing: To test a solenoid, you can use a multimeter to check for continuity between the terminals. If there is no continuity, the solenoid may be faulty and need to be replaced.
- Troubleshooting: If your car is not starting, the solenoid may be the culprit. Check the solenoid for any loose connections or damage. If the solenoid is not working properly, it may need to be replaced.
By understanding the solenoid and its role in the car starter, you can better troubleshoot and repair your vehicle if necessary.
FAQs
This section addresses common questions and concerns related to checking car starters, providing informative answers to guide readers in the process.

Question 4: How do I test the starter’s voltage?
Answer: Disconnect the battery, connect the multimeter to the starter terminals, and turn the key to the “start” position. The voltage should be between 12 and 13 volts.
Question 5: What are some common causes of starter failure?
Answer: Worn brushes, faulty solenoids, damaged windings, and loose connections are common causes of starter failure.
Question 6: Is it possible to repair a car starter myself?
Answer: While it is possible to repair a starter, it requires specialized knowledge and tools. If you are not comfortable with automotive repair, it is recommended to seek professional assistance.
Remember, a properly functioning starter is crucial for reliable engine starting. Regular inspections and maintenance can help prevent unexpected failures and ensure a smooth driving experience.
Tips on How to Check Car Starter
Maintaining a functional car starter is crucial for reliable vehicle operation. Here are some tips to guide you in effectively checking your car starter:
Tip 1: Safety First
Before starting any inspection or repair work, ensure your safety by engaging the parking brake, placing the vehicle in park or neutral, and disconnecting the battery.
Tip 2: Locate the Starter
The starter’s location varies depending on the vehicle model. Consult your vehicle’s repair manual or online resources to identify its exact position.
Tip 3: Inspect the Connections
Loose or corroded connections can hinder the starter’s performance. Check the battery terminals, starter connections, and ground connections for any signs of damage or wear.
Tip 4: Test the Starter’s Voltage
Using a multimeter, measure the voltage at the starter terminals while someone turns the ignition key to the start position. The voltage should be around 12-13 volts. Lower readings may indicate a weak battery or faulty starter.
Tip 5: Check the Solenoid
The solenoid engages the starter motor with the flywheel. Test the solenoid by listening for a clicking sound when the ignition key is turned. If no sound is heard, the solenoid may be faulty.
Tip 6: Consider Professional Assistance
If you encounter any complexities during the inspection process or suspect a major fault, do not hesitate to seek professional assistance from a qualified mechanic.
