You spend your life on the road when you’re a truck driver. With your rig being a mobile office and home away from home, it’s essential to know how to perform some basic repairs yourself if needed.

One of the most common roadside repairs is jumpstarting a dead battery.

Check for dead batteries

You should first make sure the batteries are good. Check them before you do anything, and ensure they’re not dead. 

Then, if the truck has one battery, it’s probably your best bet to jumpstart using another car or truck. If it has two batteries, you can use both cars/trucks to jumpstart it at once!

Take off caps

You’ll want to remove the battery caps, which will provide access to the battery terminals, where we will connect our jumper cables. 

Before beginning this process, you must ensure that both batteries have power, so check that each one has a charge by pressing down on them and making sure they give off some resistance.

Check the connections between each battery and its cables as well; it’s possible that these could have become eroded over time, which would prevent the flow of current from one vehicle’s battery into another vehicle’s. 

You’ll also want your cables cut at different lengths to use them effectively when jumping starting your semi-truck or other big rig vehicles with multiple batteries (like tractors).

Connect cables in a particular way (red to red, black to clean metal)

When you connect the cables, join them in a particular way (red to red, black to clean metal). Make sure you are connecting the right wires and that they are connected securely.

The car should be running long enough before you attempt to start up the truck.

Make sure car runs long enough

It’s essential to make sure you have a car that will run at least 5 minutes straight to give your semi-truck enough time to charge its battery.

If the vehicle doesn’t start, it may be because of a bad battery. If it does start but dies shortly after that, it could also be a bad alternator or starter.

Conclusion

Hoping this article helped you understand how to start your semi-truck in no time. 

While it may seem daunting, jumpstarting a big rig is just like jumpstarting a car or other vehicle, and the only difference is that you need to use the right cables and ensure that the jumper vehicle is running long enough.

If you follow these steps, you should be on the road in no time.
