How To Jump Start A Semi Truck With A Car

If you’re driving a semi-truck and your battery dies, it can be a frustrating experience. Luckily, there’s a simple solution: jump starting your semi-truck with a car. Here’s how to do it:

What You’ll Need

You’ll need a few things before you can jump start your semi-truck with a car:

• A car with a working battery
• Jumper cables
• A semi-truck with a dead battery

Step 1: Position the Vehicles

Park the car with the working battery next to the semi-truck with the dead battery. Make sure the two vehicles are close enough for the jumper cables to reach both batteries.

Step 2: Attach the Jumper Cables

Attach one end of the red jumper cable to the positive terminal on the car’s battery. Then, attach the other end of the red jumper cable to the positive terminal on the semi-truck’s battery.

Next, attach one end of the black jumper cable to the negative terminal on the car’s battery. Then, attach the other end of the black jumper cable to an unpainted metal surface on the semi-truck. This will ground the connection.

Step 3: Start the Car

Start the car with the working battery and let it run for a few minutes. This will allow the battery to charge up a bit and build up some power.

Step 4: Start the Semi-Truck

Try starting the semi-truck. If it doesn’t start right away, let the car run for a few more minutes before trying again.

Step 5: Disconnect the Jumper Cables

Once the semi-truck is running, you can disconnect the jumper cables. Start with the black cable on the semi-truck, then the black cable on the car, followed by the red cable on the semi-truck, and finally the red cable on the car.
