Can You Jump Start A Car With A Bad Starter?

Spread the love

When you turn the ignition key in your car and only hear a clicking sound, it could be an indication that your starter is failing. If that’s the case, replacing the starter would be the ideal solution. However, what if you don’t have immediate access to a mechanic or replacement starter? Can you still start your car?

You may wonder if jump-starting can work for a vehicle with a bad starter. Jump-starting a car is a common method of reviving a dead battery by using another car’s functioning battery. It involves connecting jumper cables between two vehicles and transferring electricity from one battery to another.

The idea of jump-starting a car with a bad starter may seem unlikely as the starter motor is responsible for turning over the engine. Without it, the engine won’t crank no matter how much power the battery has. Yet, there are instances where this unconventional approach works. So, before calling for a tow truck, let’s explore whether jumpstarting a car can help solve a bad starter issue.

Understanding the Role of the Starter

The Purpose of the Starter in a Vehicle

The starter is one of the critical components of your car’s engine system. Its primary function is to initiate the engine’s operation by cranking it up, making everything come to life. Once you turn the key or push the ‘Start’ button, an electrical signal goes from the battery to the starter solenoid, which activates the motor that spins the crankshaft and brings about combustion.

Without the starter, achieving the complex mechanisms necessary to start a car would be impossible manually. Thus, starters provide both crucial ease and safety for drivers.

The Different Types of Starters and How They Work

There are two types of starters available on the market – the conventional gear-reduction, high-torque starter, usually found in modern vehicles with larger engines, and the PMGR starter (permanent-magnet gear reduction), commonly seen in compact cars. While they may look different externally, working principles stay the same.

Apart from these alternative starters, there aren’t many other differences separating them. However, part of what makes various forms of engines unique is the mechanics required to transfer the power of motion to create electricity and ensure the consistent yet volatile combustions necessary inside the car.

“Starter motors can fail at any time but are most likely to be a problem when starting up in cold or wet weather.”

In cases where the starter malfunctions, whether due to age or external factors such as cold temperatures or water exposure, drivers might find themselves stranded without transportation. To avoid this unpleasant situation, jump-starting becomes mandatory.

If you’re wondering whether a bad starter could hinder your efforts to jumpstart the car, the answer depends on the problem’s severity. In some cases, a bad starter is livable with as you can jump start your vehicle by connecting it to a working battery, allowing the car to run under its own power.

Suppose there seems to be more severe damage such as grinding noises upon starting or complete failure. In that case, attempting to jump-start the vehicle becomes risky and often doesn’t work at all. Wading into unfamiliar territory DIY-style makes matters worse instead of better.

“If the starter motor just spins without engaging the engine, Check out this video for an easy way to fix the starter motor when it keeps spinning and doesn’t engage.” -ChrisFix

The situation may not always require double-checking our mechanical knowledge or rushing your car down to the mechanic immediately. Instead, if you notice anything strange happening regarding starting the car, seeking professional help from certified mechanics before deciding to act by yourself saves time and money in the long term.

While the typical lifespan of a starter is usually around five years, other factors such as external weather conditions will have an impact over the longevity of the part. When jumping starting a car, taking note of unusual sounds or behavior during startup efforts would help determine which route to take next.

How to Identify a Bad Starter

If your car suddenly won’t start and you suspect that it’s the starter, there are certain signs that can tell you whether or not your suspicion is correct. Identifying a bad starter can be difficult, especially if you’re not mechanically inclined, but here are some common symptoms to look out for:

Common Symptoms of a Bad Starter

  • Your engine won’t turn over.
  • You hear clicking noises when trying to start the car.
  • When the key is turned, the interior lights dim but the engine doesn’t start.
  • The engine starts slowly or cranks weakly, then dies or stalls shortly after starting up.

If you’re experiencing any of these symptoms, you may have a bad starter. However, before you decide to replace it, it’s important to test your starter first to determine if it really is the source of the problem.

How to Test a Starter to Determine if it’s Bad

There are two main ways to test a starter: by checking its battery connections and by performing a voltage drop test. Here’s how:

“If you don’t know what you’re doing, leave this job to professionals, because bump-starting or jump-starting a car with a bad starter could make things worse.” -Mike Allen from Popular Mechanics

To check the battery connections, simply inspect them for corrosion, loose bolts or frayed wires. If everything looks tight and clean, then move on to the voltage drop test.

For the voltage drop test, start by connecting a voltmeter between your starter solenoid’s positive terminal and the battery’s positive post. Then, have someone try to start the car. If you see a reading of 0.5 volts or more, then it’s likely that your starter has too much resistance and needs to be replaced.

Alternatively, you can also use a remote starter switch to test your starter. This involves disconnecting the ignition wire from your starter solenoid, connecting one lead of the remote starter switch to the battery positive post and the other lead to the ignition terminal on the solenoid. Then, press the button on the remote switch to activate the starter. If it turns over, then you know that the starter is good and that there may be another issue causing your car not to start.

“Jump starting may work if the starter motor happens to spin fast enough in cold weather, but it might only extend the life of a dying starter.” -ChrisFix

Keep in mind that even if your starter tests bad, you can still jump-start your car. However, this should only be done as a temporary solution and you should still replace the faulty starter as soon as possible.

To jump-start a car with a bad starter, simply connect the positive cable from the jumping vehicle to the positive post on the dead battery, and then attach the negative cable to a good ground somewhere on the engine block of the disabled car (not the negative post of the battery). Then, start the boosting vehicle and let it run for at least two minutes before attempting to start the disabled vehicle. If the disabled vehicle does not start after several attempts, then there may be another issue besides the starter.

Identifying a bad starter can be tricky, but by looking out for common symptoms and testing your starter properly, you can determine whether or not it needs to be replaced. Jump-starting your car with a bad starter is possible, but it’s not a permanent solution. Always follow manufacturer’s instructions and best practices when working with automotive electrical systems.

Steps to Jump Starting a Car with a Bad Starter

Gather the Necessary Tools and Equipment

If you find yourself in a situation where your car won’t start due to a bad starter, don’t panic. One way to get it going again is by jump starting it. To do this, you need some necessary tools and equipment. Here is what you will need:

  • A functioning car battery
  • Jumper cables (also known as booster cables)
  • Safety glasses/goggles
  • Rubber gloves (optional but recommended)

Besides these basic tools and equipment, make sure that both cars are placed in Park or Neutral gear mode and that their engines are turned off.

Connect the Jumper Cables to the Batteries

You’re now ready to proceed with the next step – connect the jumper cables to the dead battery first, then to the working battery.

  1. Start by clamping one of the red clips on the positive terminal post of the dead battery. The positive clamp is usually marked with a plus sign (+) or the letters “POS.”
  2. Next, attach the other end of the red cable to the positive post of the power source battery. Remember to connect the positive post before attaching the negative clamp. This small safety measure can prevent any spark from happening while connecting the negative side.
  3. Secure the other end of the black cable (negative clamp) onto the negative terminal of the good battery.
  4. Attach the last remaining cable, also black, to an unpainted metal surface on the stalled vehicle that isn’t close to the dead battery – such as a nut on the engine block. Avoid battery terminals or parts that could move, like belts.

Once secured, stand clear of any moving parts in both engines, and start the working vehicle. Let it run for 2-3 minutes to charge up the dead battery before attempting to turn over the Engine with the bad starter.

Attempt to Start the Vehicle

If you see some progress between clicking sounds or turning over the engine when trying to crank it – give it another go! Spare no more than fifteen seconds each time though so you can avoid overheating your action gear. If nothing happens after several tries – stop immediately and check cables alignment. It’s normal to occasionally need repositioning during this step. Ensure all quick-release clips are locked in place and try again.

On successful ignition, let the car run idle for at least thirty minutes while driving around local roads might be better suited to build-up speed gradually instead of freeway speeds right away. This helps recharge the battery properly.

Disconnect the Jumper Cables and Remove the Charger

The last step is quite simply disconnected things in reverse order: beginning with the black clamp you attached to your stalled car frame, following by removing the red clip from your power source’s positive terminal post. Repeat with the other end you put on the negative terminal cart. Finally, remove the final clamp off the charged batteries’ positive post terminal.

“Jump-starting a car with a bad starter is possible if the problem lies in the auxiliary components surrounding the ignition system, bringing fresh energy into the engine enough to overcome temporary issues. The user should seek professional advice to diagnose whether the fault persists and rectify any underlying problems.” -John Eric

Every driver will face a breakdown at some point – and while not ideal, it’s not an insurmountable challenge. By following these easy steps on “Can You Jump-Start A Car with A Bad Starter?,” you can safely jump-start a car with a bad starter and get back on the road again. Be sure to drive your vehicle around for a few minutes afterward to recharge the battery fully.

Possible Risks of Jump Starting a Car with a Bad Starter

Jump starting a car is a common method used to get the engine running when the battery is dead or weak. However, attempting to jump start a car with a bad starter can have potential risks that could cause more damage than good.

Potential Damage to the Electrical System

The electrical system in a car consists of several components like the battery, alternator, and starter. Attempting to jump start a car with a bad starter can create a power surge through the electrical system, which might cause severe damage to other sensitive electronic parts. This includes the voltage regulator, sensors, and even the car computer itself..

In some cases, the IDPM (integrated distribution module) on late model Chrysler vehicles may be damaged. It controls the transmission, air conditioning, fuel pump, horn, brakes, headlights, turn signals, and gauges as well as sending information to the PCM (powertrain control module).

A damaged IDPM, also known as body fuse box, may result in various problems such as a no-start condition, battery drain, instrument panel warning lights illumination, and loss of communication with different modules. The fix usually requires an expensive replacement part and advanced programming and configuration that only authorized dealerships can perform.

Injury from Battery Explosion or Shock

If you try to jump start a car with a bad starter carelessly, sparks or arcing could occur, causing explosions or fires. This risk becomes significant if there is any accumulation of gases like hydrogen around the battery compartment due to overcharging or leaking. Even worse, physical injuries or burns are possible if the person trying to jump-start needs to touch the cables directly; they might get electrocuted.

“A dangerous explosion can occur when a hydrogen gas buildup occurs around batteries, and the amount of charge in these types of batteries are kept secret by manufacturers.” -David Jay, an automotive expert

Additional Damage to the Starter or Alternator

If your starter is bad, there might be a mechanical problem with it. For example, the solenoid could have failed, or the wiring between the battery and starting motor is faulty. In this case, continuing trying to jump start your car will only worsen the issue further, possibly damaging other parts like the alternator or even the transmission.

“Remember that the starter requires the energy from the battery to turn the engine over as well as the help from the alternator to recharge the battery once the engine has started running. A bad starter means that you may eventually damage both of these crucial components.”-Matthew Cills, certified mechanic at

Damage to the Vehicle’s Computer System

A dead battery already puts stress on your vehicle’s computer system because it causes voltage fluctuations across all electronic parts. If you add insufficient power delivered by jumping straight to said system, extra pressure necessary for damaged starters triggers an elevated risk of frying such critical modules and central nervous systems within the rest of the car.

The potential outcome could range from intermittent operational issues, part failures such as the sending or full fuel pump unresponsive, not detecting tire forces correctly-resulting in improper handling and traction management-and much more severe flagging whole modules into limp mode.

Attempting to jump-start a car that has a bad starter should be done cautiously and ideally avoided altogether. You should always repair or replace the starter before jump-starting your car to prevent any significant risks associated with electrical damage, injury, additional costs of repairing several malfunctioning parts or permanent vehicle damage.

Alternative Solutions to a Bad Starter

Replacing the Starter with a New One

If your car starter is failing, you may be wondering if it’s possible to jump-start your vehicle. Unfortunately, that won’t work in most cases. Jump starting requires a functioning battery and alternator, but if your starter motor is broken, there’s no electrical current to activate the starter relay. Your best option would be to replace the faulty part.

The standard solution to this problem is buying a brand new starter motor. This could cost between $100-$500 depending on the make and model of your car. You can get a quality starter for cheaper by looking online or heading to an auto parts store to save a few bucks. The good thing about replacing the starter completely is that you are getting a fresh start so to speak, which means the component should work optimally without any hiccups.

“The easiest way to fix a bad starter is usually to simply replace it,” says auto expert, Steven Recktenwald, “although once in a while we might install a rebuilt part instead.”

Rebuilding the Starter for Cost-Savings

If you don’t have enough cash to buy a new starter motor, then consider re-building it yourself! In some cases, the problem could be with specific components within the starter and not necessarily the entire unit itself. By taking apart and cleaning the starter, you could fix minor problems such as rusted contacts or damaged brushes without spending too much money.

But before you commit to a DIY repair project, know that rebuilding a starter motor carries some risks. It requires technical expertise to repair properly since reinstalling improperly fixed pieces increases the chance of damage later down the line and overall safety concerns when working with electric systems.

If you’re confident in your skills and have some mechanical knowledge, then go ahead; otherwise, it is best to let a mechanic who is trained in fixing starters handle the job. The cost of repairing a starter ranges from $50-$200 with labor costs varying per hour depending on what type of work needs to be done.

“Rebuilding parts can get tricky,” cautions Matt Hill from experienced auto shop AutoNation Collision Center Clearwater, “I’d recommend leaving that part up to professionals.”

There are alternatives for fixing a bad broken starter. Jump starting your car will not work if the starter motor has failed completely, but replacing or rebuilding the damaged component could fix the issue.

When to Seek Professional Help

If you have a dead battery or a bad starter, it can be tempting to try jump starting your car yourself. However, there are times when it’s best to seek professional help instead.

When the Starter is Beyond Repair

If your vehicle has a bad starter that cannot be repaired, jump-starting the car won’t do any good. If this is the case, it’s time to call in a mechanic who can properly diagnose and repair the problem. In some cases, the entire starter may need to be replaced.

According to AAA, “Jump-starting should only be used on a healthy battery that has lost charge due to non-use or cold weather. Any other situation, such as a discharged battery or a malfunctioning charging system, could result in damage to the jumper cables or even an explosion of the battery.”

If your car’s starter is making strange noises or not engaging at all, it’s important to get it checked out by a pro before attempting to jump start the car. Without proper diagnosis, you run the risk of causing further damage to your vehicle.

When Other Problems are Discovered During Jump Starting

You might think jump-starting your car is a simple process, but it can sometimes reveal underlying problems with your vehicle. Attempting to jump-start a car with a faulty alternator or wiring can lead to electrical issues and further damage to your car.

In addition, if your car loses power after successfully jump-starting it, there may be a problem with the battery itself. This could include anything from a weak battery to a corroded connection, which requires expert attention to resolve the issue fully.

According to The Engine Block, “One common cause for a failing starter motor is loose or corroded battery terminals —and jumpstarting could very well expose them.”

While it’s always tempting to try jumping your car yourself, the best thing you can do is call a professional mechanic. With their expertise and experience, they will be able to diagnose any underlying issues with your vehicle, ensuring that you get back on the road quickly and safely.

“Jump-starting a car simply isn’t as easy as just hooking up some cables,” warns Jamie Page Deaton, executive editor of U.S. News Best Cars.

If you suspect that there might be an issue with your car’s starter or if other problems are revealed while attempting to jump start your car, it’s crucial to seek professional help. A skilled mechanic will be able to identify any underlying issues and repair them appropriately, saving you time, money, and potential headaches in the long run.
