How To Jump Start a Diesel Truck With 2 Batteries

How To Jump Start a Diesel Truck With 2 Batteries

It can be very frustrating to turn the key and have nothing happen. If you don’t have anything to do or are surrounded by friends and family who know how to jump a diesel truck, being stranded by a dead battery will never happen. If you’re away from your home, alone, or are in a hurry to get somewhere, a dead battery is not opportune.

Jump starting a gasoline-powered vehicle is easy if you have one battery. However, it is much more difficult to jump-start a diesel-powered truck with two batteries. Diesel engines are more powerful and require more cranking power. Does this matter if you get a jump-start from a friend or if you have one of the portable jump starters?

It is possible to start a dual battery vehicle with a single battery truck, as long as both vehicles are in good working order and both vehicles are properly maintained.

Why Do Diesel Trucks Have Two Batteries?

The first time you pop the hood on your diesel truck may leave you in shock! Unlike most cars, diesel trucks have two batteries. In order for diesel trucks to crank at higher amps, they need two batteries. Diesel engines require high resistance loads in order to start properly. To put it simply, diesel engines require much more power than gas engines do to turn over; compared to gasoline engines, it requires about double the amount.

How To Tell If You Need a New Battery?

You can often tell if your car is having trouble turning on when you try to turn it. The following are the signs that a battery is weak and needs to be replaced and you need to have a diesel battery jump starter:

The engine turns over very slowly.

Your engine is sluggish.

When you turn the key, your car will start to go berserk

When you turn the key, you hear a clicking sound

How To Jump Start a Diesel Truck With 2 Batteries Step by Step

Following tools will be needed for this process:

Jumper leads

Glasses

Gloves

Clamps

Donor truck

Wire brush

1. Make sure the hood is open

To jump-start a diesel truck, you must first open the hood. The truck is more difficult than small cars, but it’s easier to find the cells. The batteries in small cars are often found in unusual places, leading to them being placed in a position that you wouldn’t expect.

2. You should position the donor vehicle

The next step should be to move your donor vehicle near the truck. Next, make sure that both ends of the jumper cables are accessible to the batteries. You should have fewer worries if you are fortunate enough to have long wires. Moving the vehicles together is a good idea, but it’s important to ensure they don’t touch one another as this could cause shorting.

3. Turn off all the electronics in the vehicle

Next, switch off both the electrical components of the truck and the donor vehicle. Before you connect the donor vehicle, it is important to turn off the donor vehicle. The electronics will not receive any charge from the donor vehicle if they are turned off. It is recommended that the vehicles be shifted to neutral or parking, with the parking brakes raised.

4. Donor batteries should not be low

Two batteries are usually sufficient to power most trucks’ diesel engines. One mistake you could make is to try to start your truck with a low battery. This won’t work. It could also drain the donor battery. Before you connect the donor battery, it is important to verify its condition. You can try a different vehicle or battery if it is low.

5. Attach the Positive Terminals

There are many jumper cable brands on the market today. Every brand has its design. Most cables come with colored wires to ensure polarity. Connect the positive terminal on your donor battery to one of the truck’s batteries. Connect the jumper using the clamps marked red on each end.

6. Connect the Negative Terminals

After you are certain that the positive terminals have been connected properly, the next step is to connect the negative terminal with a metal point in the truck. Attach the black side to the terminal’s negative terminal. Next, attach the clamp to the metallic part of the dead truck.

For example, you can choose to use the engine block. Attaching the clamp for moving parts like the alternator or propeller can cause more damage to your jumper and the car.

7. Start the Donor Car

As you did in small cars, the next step is to start the donor vehicle. This is where you can give your truck the maximum power it may need to ignite. You should therefore take a few moments to get on the gas pedal. Do not be afraid. It can only go where it is parked.

8. Start the truck

The donor battery should now have enough power to turn the truck on. Turn on the ignition of the truck. The truck should start roaring and come back to life.

9. Disconnect the wires

Once your truck is fully functional, it’s time to disconnect the jumper. Remember to unplug the cable from the black/negative side first, then the positive. This will help to prevent shorting, which can lead to lower battery life. After you have disconnected the battery, close both cars’ hoods.

10. Drive the truck for about 20 minutes

Flat batteries can cause your car not to start. This means the battery needs to be charged. It is best to charge the battery before you get on the road. The alternator is designed so that the car’s batteries can be charged while it is moving.

After jumpstarting your car, you should drive it for 20 minutes before you stop. You may need to give your car more charge the next time it starts. You may find yourself in the same situation if you turn off your truck immediately.

The Do’s and Don’ts of Jump Starting

Jumpstarting Do’s

Turn on the heater for the vehicle with the dead battery. This will protect the electric system in case of a surge in voltage during jumpstarting. If the connections or battery terminals are corroded, keep a wire brush on hand. To determine if your car is equipped with “jump-start plugs,” read your owner’s manual Place the cars, so that jumper cables reach both batteries easily, but don’t allow them to touch each other. Before connecting the jumper cables, verify the voltage of the batteries in both vehicles. Both vehicles must be in the park. If you have the option, wear protective eyewear If rubber gloves are available, wear them

Jumpstarting Don’ts

When you connect the jumper cables to either car, do not smoke Jump-start a battery that has a cracked or leaking fluid. Do not attempt to jumpstart the battery if the battery temperature drops below freezing. You should not place your face or body over the batteries. Don’t “gun” the engine to provide the jump but rev the engine by pressing the accelerator steadily. Do not allow the jumper cables’ ends to come in contact with one another

Things to Consider

It is a tricky process, and you should follow all the precautions and tips before starting it.

If the products are damaged or leaking, stop using them. When connecting devices, do not touch wires or the devices.

When you are using some products, check the material of them, In case the able is torn, or its wires are bare, do not use them.

If the heat builds up, disconnect it immediately. If you’re in extreme conditions, thick insulation materials are recommended. Extreme cold or heat can cause rapid draining of your truck’s battery.

The engine’s fuel is flammable and produces many flammable gasses. Do not smoke while it is burning. It is best to keep your children away. To protect yourself, wear safety glasses and a safety dress. Take out all jewelry from your hands and arms.

After turning off the engines, disconnect the wires. They should not be removed while the engines are running. You could get an electric shock.

Jump-starting a frozen battery can cause it to explode. If you notice any bulging on the sides of the battery, it has likely frozen. This is necessary to avoid any injury or damage to your equipment.

If the donor vehicle’s voltage is excessive, keep the heater on in the pickup vehicle. This will protect the wiring in the pickup.

Auto Repair: Jump-Starting Diesel Batteries

Even though diesel-powered vehicles can have dual batteries or one oversized battery, it’s possible to jump-start a diesel from the battery on a conventional gasoline-powered vehicle. To avoid confusion, in this section I call the vehicle with the dead battery the disabled vehicle and the one you’re jumping the start from the source vehicle. Follow these steps to jump-start a dead diesel battery:

Make sure that both vehicles are in Park or Neutral with the parking brakes on. Turn on the heater on the disabled diesel vehicle to protect the electrical system from surges in voltage. Make sure that the lights and other electrical accessories on the disabled diesel vehicle are off. A vehicle with dual batteries usually has thicker cables on one of the batteries. If either vehicle has dual batteries, always attach the jumper cables to the battery with thicker cables. If either vehicle has dual batteries with cables of the same thickness, use either battery for the jump. If a vehicle has only one battery, just be sure to hook the cables up in the proper order. Connect the clamp on one of the jumper cables to the positive terminal of the disabled vehicle’s battery. The positive terminal should have a (+) or a red cover on it. Connect the other end of the same jumper cable to the positive terminal of the source vehicle. Connect one end of the other jumper cable to the negative terminal (-) of the source vehicle. Here’s the tricky part: Connect the other end of that jumper cable to an unpainted, metallic part of the disabled vehicle. I often use the bracket that keeps the hood up, but any such part will do as long as it’s not near the battery, belts, or any other moving parts of the engine. Start the engine on the source vehicle. Start the engine on the disabled vehicle, and let both engines run for a minute or two, more if the battery has been dead for a long time. Turn off the engine of the source vehicle. (Leave the disabled vehicle’s engine running.) Remove the cable from the unpainted metal part of the disabled vehicle. Disconnect the cable from the positive terminals of both vehicles. Disconnect the cable from the negative terminal of the source vehicle. The disabled vehicle should be driven around for at least 15 minutes to ensure that the battery is fully charged.

Tip: If you jump-start a dead diesel vehicle and the battery dies the next time you try to start the car, you probably need a new battery. Be sure to get theproper one for your vehicle’s make, model, and year.

How To Charge A Diesel Truck With Two Batteries – Prosource Diesel

Written By: ProSource Diesel

If you’ve just recently bought a diesel truck, or are unfamiliar with diesel trucks in general, you might be surprised to learn that they have two batteries. As the weather gets colder, it’s a good idea to get familiar with your two-battery setup and find out how to jump-start or charge your truck batteries if they die.

Why Do Diesel Trucks Have Two Batteries?

The short answer is that diesel engines have higher compression and more resistance than gas engines. It simply takes more power to start them up. As an example, the normal compression ratio for a diesel engine is somewhere between 15:1 and 20:1. Gas engines are only around 10:1. A higher compression ratio means a more efficient engine, but it also means a higher resistance load, which makes the engine harder to start. Along with needing two batteries to get it started, the high compression ratio also requires sturdier parts. This is why diesel truck parts are constructed more durably than similar parts for gas engines.

Charging a Diesel Truck With Two Batteries

If your batteries die, then you can either charge them with a battery charger, or you can jump-start them using another vehicle. After the truck is started, you would simply have to drive for about 30 minutes until the alternator recharges the batteries. Let’s first take a look at how to charge your batteries with a charger.

The first thing to know is that you will need two battery chargers. One for each battery.

Step 1 – Disconnect the negative terminal on one battery, followed by the positive terminal. Repeat the procedure with the second battery.

Step 2 – Connect the positive clamp of one of the chargers to the positive terminal of one of the batteries. Attach the negative clamp to the negative terminal. Repeat the process on the second battery with the second charger.

Step 3 – Set the chargers to charge on low amperage. This will take longer, but you’ll have a more complete charge.

Step 4 – Turn off the battery chargers after two hours and try to start your truck. If it doesn’t start, use the previously mentioned process to reattach the chargers and charge for another hour.

Step 5 – Reinstall the battery terminals by starting with the negative terminals.

Jump-Starting a Diesel Truck With Two Batteries

If you don’t have time to wait for your batteries to charge or your batteries have died away from your charger, then you’ll need a jump-start. In order to do this, you’ll need a second vehicle that is running and two jumper cables.

Step 1 – Turn on the heaters of both vehicles, but turn all other electronics off, including the lights, stereo, windshield wipers, etc. Turn off the engine of the running vehicle, engage the parking brake, and put both vehicles in park or neutral.

Step 2 – Attach the jumper cables to the dead battery with the thickest cables, if possible. If the cables are the same thickness, then it doesn’t matter which one you attach the jumper cable too.

Step 3 – Clamp one jumper cable to the positive terminal of your chosen dead battery, and then clamp the other end to the other vehicle.

Step 4 – Attach the second cable by starting at the other vehicle’s negative battery terminal. Ground the other end of the second cable by attaching it to a piece of solid metal on your truck.

Step 5 – Start the engine of the other vehicle, then start the engine of the dead vehicle. Let both vehicles run for a few minutes. Shut off the engine of the other vehicle.

Step 6 – Remove the grounded cable from your truck first, then remove the cables from the positive terminals of each vehicle. Remove the cable from the negative battery terminal of the other vehicle.
