What happens if you connect jumper cables wrong?

Fuses (and/or fusible links) act as circuit protection devices between the battery and the vehicle's electrical system. Connecting the jumper cables backwards will often result in one or more blown fuses. The affected circuit will not function correctly until the blown fuse is replaced.

Do you connect both jumper cables?

Attach one red jumper cable clamp to the positive terminal on the dead battery. Attach the other end of the same cable, the second red jumper cable clamp, to the positive terminal on the working (live) car battery.

How do you use jumper cables to start a dead car?

Turn off the ignition on both cars. First, clamp one end of the positive cable to the dead battery's positive clamp. Now have a helper connect the other end of that cable to the other battery's positive clamp. Next, connect the negative cable to the negative terminal on the good battery.

Does revving the engine charge the battery?

The battery will charge faster if you rev the engine faster. Why? Because the faster the crankshaft turns, the faster it turns the belt that runs the alternator. And the faster the alternator turns, the more electricity it produces to run all the electrical stuff in the car — and recharge the battery.
