Dead Car Battery Will Not Jump Start. That said if there is no underlying charging system problem or problem with something draining the battery when the car is supposed to be off a jump start and driving the car will. Now have a helper connect the other end of that cable to the other battery.
I bet you see it drop to 3 volts. However this is not to mean. Connect one of the red positive jumper cable clamps to the dead batterys red positive post.
If you cant test the battery try jump-starting.
Heres how. Check for these common symptoms of a dead battery. Even if that doesnt. Therefore if the only problem with your battery is that its dead you can expect to receive help from a jump start.
