Can You Jump a Car in the Rain?

The last thing you want to happen is your car to stop running in the middle of the rain. It is already a big inconvenience in itself. But aside from that, some people also don’t advise jumpstarting a car during this weather condition. Is this true? Or can you jump a car in the rain?

According to experts, jumpstarting a car in the rain is safe and will not cause any harm since the electrical system in cars has a very low voltage. The water is not an issue as long as the jumpstarting process is done in proper sequence.

Read on to learn more about jumpstarting a car in the rain.

Automotive professionals say that jumpstarting a car in the rain is safe and will not cause any harm. This is because the electrical system in cars is not high enough to pose any danger. The water is not an issue, either, as long as the jumpstarting process is correctly done.

Of course, jumpstarting a car in the rain is not ideal. It is the last thing that you would want to experience. But if you don’t have a choice, it’s good to know that it is possible.

Here are ten steps for jumpstarting a car battery in the rain:

Jumper Cables Should Be in Good Condition
Take All Necessary Precautions Before Jumpstarting a Car
Check the Location of the Batteries
Read the Owner’s Manual
Turn Off All Electrical Items
Connect the Clamps
Avoid Cross Connecting Cables
Start the Car with a Good Battery
Start the Car with the Dead Battery
Disconnect the Cables in the Correct Order

Let’s briefly explain each step:

1. Jumper Cables Should Be in Good Condition

First, you need to ensure that the jumper cables are not worn out and are in excellent condition. This is because the insulation can get damaged if the cables are bad. This can result in a short circuit, especially if the water gets into the cable.

It is best to protect yourself and the car battery from the rain using an umbrella. That’s why it is best to have someone assist you in this kind of situation.

2. Take All Necessary Precautions Before Jumpstarting a Car

The next thing to do is take all the necessary precautions before starting your car. This means wearing gloves and having a presence of mind.

This way, you will be able to connect leads in their proper order. At the same time, you will never forget not to touch both battery terminals simultaneously. Your car battery may only have 12 volts, but you still need to be careful.

3. Check the Location of the Batteries

Jump leads are typically a few meters long only. That’s why you have to check the location of the car batteries. Ensure that the running car is positioned to close both batteries as possible.

There are vehicles with car batteries located in the trunk. It is possible to find the jumpstart terminals beneath the hood in this case.

Also, don’t forget to double-check the jumper cables to ensure that they are in good condition. There should be no cuts and tears on the plastic insulation, and the clamps must be firmly connected to the cables.

4. Read the Owner’s Manual

You are familiar with the Owner’s Manual, which came along with your car when you bought it. It has a specific section dedicated to jumpstarting. Read and follow the guidelines to prevent damaging your car and the running car.

5. Turn Off All Electrical Items

The electrical items you won’t need for jumpstarting must be turned off. These include the air conditioning system, windshield wipers, radio, and lights. This way, you won’t be wasting power on unnecessary electrical items.

6. Connect the Clamps

Each car battery has two terminals which come in red and black. The jumper cables come in red and black too. When you connect the cables, make sure to hold both clamps. This way, you will prevent them from touching any metal.

Logically, you must connect the red cable to the red terminal of the working battery. Then, connect the other clamp to the dead battery’s red terminal. As for the black cable, it must be attached to the black terminal of the running battery. But you don’t have to attach the other clamp to the dead battery.

Instead, connect it to a non-moving metal component as far away from the battery. This will avoid sparks from igniting the hydrogen gas produced by the battery.

7. Avoid Cross Connecting Cables

Make sure not to cross-connect the cables. If you accidentally attach the red terminal to the black terminal, this will result in a short circuit. That’s why the presence of the mind is significant.

8. Start the Car with a Good Battery

The next step is to start the car with the running battery. Then, let it idle for a few minutes to add some charge to the dead battery.

9. Start the Car with the Dead Battery

If your car doesn’t have any other engine issues, it is expected to start easily.

10. Disconnect the Cables in the Correct Order

Once your car is running, you can start disconnecting the jumper cables. Remember to carefully remove the black cable first and then the red cable. Ensure that the clamps will not touch any metal component as you remove them.

After following these steps, drive your car and let it idle for about 30 minutes. Letting it idle will give the alternator time to recharge the car battery. Also, it is best to attach a battery charger as soon as possible to charge the battery fully.

How to Jumpstart a Car in the Rain

Jumping a car in the rain is not dangerous if you properly do it. Even if it isn’t raining, you have to do the jumpstarting process correctly to avoid any harm.

Here are some reminders when jumpstarting in the rain:

Avoid raindrops from falling on battery terminals
The battery must not be frozen before jumpstarting
Do not connect incompatible cars (e.g., 6-volt and 12-volt batteries)
Red is positive, and black is negative
Connect cables carefully, tightly, and securely
Red clamps must be connected first
Disconnect the black clamp first
Don’t let the cables touch each other

Is Jumpstarting a Car in the Rain Safe?

Jumping a Car in the Rain Is Not Dangerous

Jumping a car in the rain is not dangerous. Well, you will most likely get soaking wet. Worse, you might catch a cold or even the flu. But if you wonder if you will get electrocuted by your vehicle, this will not happen.
