What are the Causes to Why My RAV4 Won’t Start After Battery Change?

RAV4 Won’t Start After Battery Change

There are several reasons why your RAV4 won’t start after a battery replacement.

Keep reading to find out the top 5 reasons!

Reason #1: Faulty Starter

If the car receives electricity and the lights come on, but the engine won’t start, you could deal with a separate issue.

It’s conceivable that you misdiagnosed the dead battery.

A faulty starter could make a growling noise when you try to start the car. However, it could also result in complete silence.

Reason #2: Stuck Engine

Another option is that you thought you had a faulty battery when, in fact, the engine was seized.

You could recall some engine failure signs if you remember the last time the automobile was operating.

It’s possible that you smelled burning or saw the smoke.

Additionally, there could have been odd engine noises like banging or tapping.

Reason #3: Corrosion of Connectors

Batteries’ terminal posts and connectors degrade with time. Corrosion is brought on by the hydrogen fumes produced by the battery acid.

Corrosion might obstruct the connection if it progresses too far. On the other hand, if the rust is severe enough, the automobile may not even start.

Reason #4: Battery Installed Incorrectly

If you install a brand-new battery under the hood of your RAV4 and the vehicle still won’t start, you should look at the installation.

Are the cables in excellent condition, and were they firmly clamped down? If this is the case, the battery won’t be able to start the automobile.

The positive cable must also be in good condition to its junction with the starter.

Additionally, the battery needs to work with your RAV4. Not all vehicles use car batteries. To start the engine in your RAV4, you require a specific size and capacity.

Consult the owner’s handbook if you’re unsure about your required battery.

Reason #5: The Alternator is Not Working Properly

The alternator may be to blame if you could start your RAV4 after replacing the battery, but it didn’t stay running for very long.

Even though you may have had enough power after installing the fully charged battery to begin going, it won’t last if the alternator doesn’t recharge it.

One of the most frequent errors is replacing a battery when the alternator is the underlying culprit.

Because of this, it’s crucial to accurately assess the dead battery in your RAV4 before making a choice.

How To Fix RAV4 So You Can Turn it On After Battery Change?

There are quite few fixes for your RAV4! Keep reading to find out which can be applied to your RAV4! 

If this doesn’t work, it is advisable to visit a mechanic. 

Fix #1: Examine the Battery

Checking the battery must be your first action. To begin, check the connections to make sure they are all secure.

Additionally, you should make sure that the connectors don’t have any rust. If there is, rinse it off with a solution of baking soda and water. The best solution is this one, which is also nearly cost-free.

Use a voltmeter to check the charge’s status if you are using the correct battery and all connections appear secure.

It must show 12.6 volts or more. The battery is dead if it doesn’t. However, if the battery is brand-new, you should proceed to the following step.

Fix #2: Examine the Alternator

Use a voltmeter to check the alternator while the car is moving.

The battery voltage should increase when the engine is running if it is ultimately charged.

That is a result of the working alternator charging it. The alternator will fail if the voltage doesn’t increase or drops.

Take the alternator to the auto parts store for a free check if you can’t start the vehicle for a check.

Fix #3: Examine the Starter

The starter has to be checked to see if all the interior lights and accessories are functional, but you still cannot start the vehicle.

The starter’s motor and solenoid are only two of the many components that might malfunction.

The starter can be tested for free at several car parts outlets.

If you are unsure how to accomplish this, simply remove it and bring it to the near-by business.
