If your truck has been sitting for a while and won’t start, you may need to jump-start it. Here’s how to do it safely:
- Engage the parking brake and put the truck in Park or Neutral.
- Locate the battery terminals; the positive terminal is usually red, and the negative terminal is typically black. If you jump-start a diesel truck, the positive terminal may be marked with a “+” sign.
- Attach the red cable to the positive terminal and the black cable to the negative terminal. If you jump-start a diesel truck, ensure the cables are correctly attached before starting the engine.
- Start the working vehicle’s engine and let it run for a few minutes. Then, try to start your truck. If it doesn’t start, let the working vehicle run for a few more minutes before trying again.
- If your truck still doesn’t start, you may need to replace the battery.

Jump-Starting a Truck with a Car
Diesel trucks are fuel-efficient and powerful, but starting them in cold weather can be challenging. You can jump-start your diesel truck with a car, but be sure to follow the instructions in your owner’s manual to avoid damaging your batteries or electrical system.
Connecting the Negative When Jumping a Car
Never connect the black cable to the negative terminal when jumping a car. This could result in an explosion. Always connect the black cable to the positive terminal to prevent accidents.
Jump-Starting a Completely Dead Battery
You can jump-start a completely dead battery but follow safety precautions. Ensure both cars are turned off when connecting the jumper cables. Always connect the wires to the dead battery first to prevent sparks or electrical surges.
Household Items You Can Use to Jump-Start a Car
In a pinch, household items can help get your car going again. A can of Coke can clean battery terminals, hand sanitizer can thaw frozen locks, and cooking spray can lubricate sticky locks. Kitty litter can provide traction if your tires are stuck in the mud, and rope can be used to tow a car short distances. Toothpaste can fill small cracks in windshields, and boiling water can help remove ice from windshields and locks.
Does Revving the Engine Charge the Battery?
The alternator charges the battery while the engine is running. Revving the engine will spin the alternator faster and produce more electricity, but don’t rev the engine too high, or you could damage it.
Conclusion
Jump-starting a truck is a simple process, but following safety precautions is essential to avoid accidents. You can jump-start a diesel truck with a car; household items can help in a pinch. Remember to connect the cables correctly and follow the instructions in your owner’s manual. If your battery is entirely dead, try jump-starting it before replacing it.
