If your commercial truck has been sitting for a while, you may need to jump start it before you can hit the road again. Jump starting a big rig is a little different than jump starting a regular car. Here’s how to do it:
First, make sure that the battery terminals are clean. If they’re not, use a wire brush to clean them off. Next, connect the positive (red) cable to the positive terminal on the battery, and then connect the other end of the cable to the positive terminal on the other battery.
- Park the semi truck on a flat surface, if possible
- Otherwise, make sure the truck is parked at an incline with the nose pointing downhill
- Connect one end of the jumper cables to the positive terminal of the dead battery
- Connect the other end of the jumper cables to the positive terminal of the live battery
- Connect one end of a second set of jumper cables to the negative terminal of the live battery
- Have a helper start their engine and let it idle for 5-10 minutes while you monitor the ammeter on your dash panel (if so equipped)
- If you don’t have an ammeter, keep a close eye on both batteries to make sure they’re not overheating
- If everything looks good, continue to step 6
- If not, disconnect everything and seek professional help as soon as possible! 6
- Once your helper’s engine is running smoothly, connect the final cable to your truck’s negative battery terminal and let it run for another 5-10 minutes before starting your own engine
