Can You Jump Start A Semi With A Car

It’s a common question: can you jump start a semi with a car? The answer is yes but it’s not as simple as jump starting a car with another car. Here’s what you need to know about jump starting a semi with a car.

First you’ll need a heavy duty jumper cable that is at least 20 feet long. You’ll also need another vehicle with a working engine to serve as the “jumper.” Be sure to park the jumper vehicle as close to the front of the disabled semi as possible and turn off all lights and accessories.

Next open the hoods of both vehicles and locate the batteries. On the semi the battery will be located in the engine compartment. For the jumper vehicle it will be under the hood.

Attach the red (positive) clamp of the jumper cable to the positive terminal of the dead battery on the semi. Then attach the other red clamp to the positive terminal of the jumper battery. Next attach the black (negative) clamp of the jumper cable to the negative terminal of the jumper battery. Finally attach the last black clamp to a clean unpainted metal surface on the disabled semi (this will serve as the ground).

Now start the jumper vehicle and let it run for a few minutes. Then try starting the semi. If it doesn’t start you may need to repeat the process.

It’s important to note that jump starting a semi is different than jump starting a car. The battery in a semi is much larger and the engine is also much larger. As a result it takes more power to start a semi than it does a car. That’s why it’s important to use a heavy duty jumper cable and to have the jumper vehicle running for a few minutes before trying to start the semi.

If you don’t have a jumper vehicle or a heavy duty jumper cable you can also call a tow truck. Most tow truck companies have the equipment needed to jump start a semi.
