How do I jump-start a diesel truck with a car?

How do I jump-start my diesel truck if my friend only has a car? I really need a jump and I don't know what to do.

Answer
You can definitely jump-start your diesel truck with a car.
Although most diesel trucks have two batteries, they run in parallel. As long as you’re able to charge one, the other one will also work. If you or your friend has jumper cables, you’ll be able to jump-start your truck.
To jump-start your diesel truck, follow these steps:
  • Connect the red cable clamp to the positive terminal of your truck and then connecting the second clamp to the other vehicle’s positive terminal
  • Repeat the same process for the black clamp, but connect it to the other vehicle’s negative terminal and attach the other clamp to a piece of unpainted metal on your truck (or your negative terminal)
Let the battery charge for a minute or so before turning on the truck. If you wait and try to turn the ignition but nothing happens, it needs more time.
Once you get the engine to turn over, leave your truck running for at least 20 minutes. Doing so ensures your batteries remain charged.
You should also consider adding towing and labor coverage to your truck insurance policy. Call your provider to add it, or if they don’t offer it, compare quotes on the Jerry app in just minutes to find the best rate possible.
