Once you're running again, do a quick search to figure out what drained your battery in the first place. You may allow the revived car to idle for a minute to give the battery a good charge, but the ride home should be more than enough to get you juiced back up. If it starts, immediately remove the negative cable attached to the now undead car's engine block first, then remove the rest of the connections. Step 6: Attempt to start the disabled vehicle. Allow the donor vehicle to run for about 30 to 60 seconds. Step 5: Double check your connections, then start the donor vehicle to begin the charging process. Most engines have a metal tab sticking out somewhere near the front that's perfect for this, but any exposed metal on the engine block or the vehicle's body will usually do.
Step 4: Instead, take the remaining negative clamp and connect it to the dead vehicle's engine block. You're starting to rethink that eye protection now, huh? That can change the voltage of the circuit you're creating with the cables and cause all sorts of electrical issues, from blown fuses to (on rare occasions) exploding batteries. Connect the positive clamp (red) to the positive terminal of the dead battery (also red), but don't connect the negative clamp to the negative terminal. Step 3: Grab the other end of your jumper cables, being careful to avoid touching the exposed teeth of the other end of the cables and to avoid touching these now electrified clamps to each other. Note the terminal posts on the donor car's battery and connect the negative clamp (black) to the battery's negative terminal (also black) and the positive clamp (red) to the positive terminal (also red).
Step 2: Grab one end of your jumper cables. Shut down both engines to avoid damage to the electrical systems.
Position the vehicles' to get the two batteries as close together as possible to allow room to work and for the jumper cable to reach. Step 1: Note the orientation of the cars' batteries in the engine bays. your disabled car with a drained battery.A ground point is any bare metal point of the car that can conduct an electric current without interruption if you can’t find a ground point to safely latch the negative cable to, then simply connect the remaining end of the negative cable to the negative terminal of the dead battery. Afterward, grab the negative cable (black) and connect one end to the negative terminal of the good battery, then, connect the other end of the black cable to a ground point on the dead car. Once this is done, you can start connecting the jumper cables from battery to battery.įirst, connect one end of the positive cable (red or orange) to the positive terminal of the dead battery, then connect the other end of the same cable to the positive terminal of the good vehicle’s battery. If all this is in check, put your cars as close together as possible with the hoods unlatched, and turn them off completely. Whether it’s a friend or a complete stranger that comes to help you, their car is going to have a healthy battery, and one of you will have to provide a set of jumper cables for this to work.
