Can You Remove Jumper Cables While Car Is Running. Do not let the clamps touch each other while any part of the cables is still attached to a. Ive heard that recommended but I think its right up there with dont use your cell phone while pumping gas.

Start the engine of the dead car and let it run for a few minutes. Once the dead car is running you may disconnect the jumper cables starting with the black negative cable clamps. When I jump to start it it fires up real good but immediately dies when I remove the cables.
While the engine of the functional car is still running let the jumper cables stay connected for a while.
Hi my name is thomas and my craftsman tractor lawn mower model number 917273012 has a battery that is appx 1 year old. I go to disconnect the jumper cables and car dies. Always connect and remove jumper cables in the proper order to prevent sparking. You could have a faulty alternator.
