It’s a bright morning and you’re rushing towards your truck to get on the road. You hop into your vehicle, turn the key but….. NOTHING. The engine doesn’t roar to life. You check the dash and see that the battery light is flashing. Must be a frustrating feeling, right? But what if we told you you can jump-start your vehicle?
Yes, this method can help you avoid wasting time, money, and a lot of stress! But how exactly can you do that? In this blog, Waraich Mechanicals - a leading truck repair shop in Rocklea - will share useful tips to properly jump-start your vehicle and avoid the headache of unexpected downtime.
But before anything else, it’s important to understand your truck’s battery!
Jump Start A Vehicle: Understanding Your Truck's Battery
Most of the trucks are powered through 12-volt or 24-volt lead-acid batteries for starting the engine and other vital systems. Knowing what type or condition your battery is in will help a lot in case you have to troubleshoot or even jump-start the battery.
Jump Start A Vehicle: Common Battery Issues
Just like humans, your truck’s battery is the heart of its electrical system. When it fails, you’re not going anywhere. So, what exactly affects it? Here are some common battery issues that can help you recognize warning signs early:
- Age: All batteries tend to lose their capacity as they remain for longer in use.
- Extreme weather: Both extremely high temperatures and extremely low temperatures do adversely affect the performance of the battery.
- Parasitic drain: Leaving electrical devices turned on while the engine is off can cause the battery to run out.
- Corrosion: Battery terminals may get corroded. Thus, hindering the passage of currents appropriately.
Jump Start a Vehicle: Essential Tools
Alright, now that you’re aware of the common battery issues, it’s time to get into action. First things first, gather the essential tools you need to get your vehicle roaring back on the road!
Here’s what you’ll need to have on hand before attempting a jump-start:
- Jumper cables: For trucks, it is advisable to use heavy-duty cables with a gauge size of no less than 4 AWG.
- A working battery: Use another vehicle with a working battery i.e truck or car for jump-starting.
- Safety gear: Use gloves and safety goggles to minimize the risk of injuries in case flying sparks occur.
Jump Start A Vehicle: Key Safety Precautions
Gathering the right tools isn’t enough when it comes to jump-starting your truck. Since you’ll be working with electrical equipment, you also have to prioritize your safety.
Here are some recommendations on how to jump-start a vehicle while minimizing the risks:
- Inspect for damage: Assess the batteries and cables for physical damage and deformation before starting to avoid fizz or leaks.
- Avoid sparks: Do not put any metallic items near the battery terminals to prevent any possible short circuit.
- Choose a well-ventilated area: Gasses are emitted from the batteries, especially during a jump-start. Always perform this task in an open and ventilated space.
- Wear protective gear: To some, this may seem unnecessary but wearing gloves and goggles protects you from battery sparks or battery acid.
Jump-Start A Vehicle: Step-by-Step Guide
Safety measures in place? Right tools gathered? Bingo! It’s time to hit the ground running! Here’s what you need to do to jump-start your truck in 2025:
- Position the vehicles: Place the vehicle with the functioning battery close to your truck. Especially, if a working vehicle is about 18 inches from your truck. Switch off both vehicles and all their electrical equipment.
- Connect the jumper cables: Open the hoods and locate the positive (+) and negative (-) battery terminals. For those who are doing it for the first time, let us tell you that the positive terminal is marked red and the negative terminal is marked black.
- Attach the positive cables: Connect one end of the red (positive) jumper cable to the positive terminal of the battery having no energy. Then, attach the other end of the battery to the positive terminal of the live battery.
- Attach the negative cables: Now, connect one end of the black (negative) jumper cable to negative terminal of the working battery. Attach the other end to an unpainted, metal surface on the disabled vehicle. Away from the battery to ground the connection safely.
- Start the working vehicle: Start the functional car battery and leave it running for a few moments in order to charge the flat battery. Also, make sure that the two vehicles are in neutral throughout the whole operation.
- Start the disabled vehicle: After a few minutes of letting it sit and with some difficulty starting the dead battery vehicle, attempt to start it again. If it still does not start, wait a little bit more then try again. Do not use any electric devices while in the process of providing a jump start.
- Disconnect the cables: Once the truck starts, remove the cables in the reverse order. Meaning, you need to remove black cables from the handicapped truck and then from the working truck. Done? Now remove the red cables from the working battery followed by the dead battery.
- Let it run: Time to bring your truck into action! Let the revived vehicle run for at least 20–30 minutes to further charge the battery. Still struggling to hold a charge? We recommend having both battery and charging system checked by a professional like Waraich Mechanicals!
