Can a Bad Starter Cause Electrical Problems? 10 Common Problems and Solutions

The starter is a component of your vehicle’s electrical system and is susceptible to blown fuses and short circuits. When you’ve been desperately trying to start your car, the starter can overheat, increasing the likelihood of electrical problems and the accompanying smoke.

Increased electrical demands on charging systems have increased alternator failures. A failing starter may crank the engine too slowly for a quick start or not crank at all. A low battery or a loose or corroded battery cable connection is frequently the source of the problem.

Second, can a faulty starter result in a short? Any issue with the wires that connect to the starter solenoid can cause a short, resulting in a burnt smell or smoke.

10 common problems and solutions

It’s no surprise that people take their cars’ functionality for granted because they’re so simple to use. With a simple turn of the key, you can be on your way anywhere in the USA by pushing a few pedals with your feet and maintaining a firm grip on the steering wheel. It may come as a surprise that there is much more to the systems that keep cars safe and running reliably than meets the eye. The starting system is one of the most effective operational systems in any vehicle. This system has numerous components, and if any of them fail to operate or malfunction, the car will not work.

 1. Engages, but the engine doesn’t turn.

Presuming your battery is healthy and fully charged, turning the key, and hearing the clunk of the starter active engagement, but the motor not turning can indicate several things. A loose or corroded electrical supply is the most common cause of this type of fault.

If there is a problem with the starter motor’s internal windings, bad brushes, or other electrical faults, the starter motor may not be able to crank the engine. Mechanical issues, such as bad bearings inside the starter or teeth no longer combining in the starter or ring gear, could also exist if you turn the key and only hear a thunk or a click.

2. The starter turns but doesn’t turn the motor.

The pinion gear of a starter motor does not always engage the ring gear on the flywheel. Instead, the starter uses the Bendix, which is nothing more than a giant electromagnet, to push the smaller bag out to engage with the flywheel. This is what pushed the pinion gear out and into contact with the flywheel if you turn the key and only hear a whirring or grinding sound.

3. Starter Motor Stays On

If the starter stays on, and you’ll know because there’s a lot of noise, turn off the engine as soon as possible – a stuck solenoid can sometimes cause this, and the only solution is disconnecting the battery.

This is a severe problem, and driving the car will only worsen. Driving it will severely damage the starter system’s electrical and mechanical components.

4. Nothing happens at all, maybe a slight clicking.

If you turn the key and get nothing or just a tiny click, the cause is usually a dead battery rather than a bad starter. However, if the battery is good or does not crank with a jump start, it could be a starter problem. When you turn the key, nothing happens.

5. Sporadic Starting

Does your car start properly some of the time but not others? Assuming, once again, that your battery is in good condition, this can only be one thing: the starter motor or solenoid.

The solenoid either sends total current to the starter or it doesn’t, and something as minor as engine heat expansion can cause it to fail temporarily. Some models are notorious for this. One bad internal winding or a wrong spot on the starter’s commutator can also cause intermittent problems. Intermittent problems rarely improve and frequently worsen.

6. Failed Starter

When a car begins to have trouble starting or completely fails to start, one of the first things people think of is a bad starter motor. When you turn the key, a failed starter will frequently produce a single loud click or a series of click, click, click. This is the sound of a starter activating but failing to engage with the flywheel and spin the motor.

7. Faulty Alternator

The alternator is a belt-driven device that generates a spark in the engine and charges the vehicle’s battery while the car is running. If the alternator fails, the battery will be drained of its power as it takes overpowering the accessories that the alternator would normally power during vehicle operation. The car will not start the next time you try to create it.

8. Dead Car Battery

A dead battery is without a doubt one of the most common reasons a car will not start. The battery is in charge of providing the initial electricity required to start the vehicle. If accessories or lights are left on or have reached the end of their expected lifespan, they will die.

If you’re having trouble starting your car, don’t put off going to an auto repair shop. Lloyd’s Automotive and Transmission Specialists is an excellent place to start when it comes to problem diagnosis in Olympia. Our team will quickly identify the problem and return your vehicle to dependable condition.

9. Checking the Battery Voltage

You must determine whether you have enough juice to power the starting motor by checking the voltage in your battery with a voltmeter.

Set your voltmeter to a range higher than the voltage of the battery, such as 20 volts on the DC (direct current) voltage scale.

Connect the test leads from across battery terminals and turn on the meter. Touch the negative lead to the battery’s negative (-) post, and the positive lead to the battery’s positive (+) post.

Turn on the headlights of your vehicle.

10. Inspecting Cables and Wires

Corrosion at battery connections obstructs electrical flow. This is a regular issue with a battery or starting system that hasn’t gotten much attention. If you observe a film of corrosion about one or both batteries, wash them with a baking soda-warm-water solution.

Final Verdict

When you start your vehicle, your interior or dashboard lights may dim due to a short circuit somewhere in the internal wiring. When this short occurs, your starter motor attempts to draw additional power. As a result, other systems, such as your lights, are drained. A chugging sound may be heard in addition to the dimming lights. 

This could be a sign of a motor-bearing failure, and your vehicle requires immediate attention. When you turn the key, you should hear a grinding sound, which indicates a mechanical problem rather than an electrical problem. Typically, the culprits are the gears that connect to your starter motor.
