What happens if you connect jumper cables to both terminals?
It could explode. You can tell if it’s frozen by looking through the inspection cap to see if the water is frozen. One or more sides of the battery case will bulge if it’s frozen. Make sure you can identify the positive and negative terminals of both batteries to know how to put on jumper cables.
When hooking up the jumper cables the last cable to connect negative should go where?
The negative (black) cable should have one end attached to the negative terminal of the dead battery, and one end grounded. The safest order to attach the jumper cables is as follows: Attach one red jumper cable clamp to the positive terminal on the dead battery.
What happens when you connect a jumper cable backwards?
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. Reversing the battery cables creates a surge of electrical current that can easily damage the battery.
What should I do if my jumper cable is short?
Normally the only needed repair is to replace the multiple blown fuses. When you have a fuse that blows repeatedly, something has become totally shorted. Given the history, we can assume the short is not due to a bare wire or other things associated with age or mileage.
Where does the red jumper cable go on a car?
The other end of the red cable connects to the positive terminal of the good battery. One end of the black (negative) jumper cable connects to the negative battery terminal of the good battery. The other end of the black jumper cable connects to a good ground on the vehicle that won’t start.
What happens if you connect a jumper cable to a dead battery?
Connecting the jumper cable to the negative terminal of the dead battery can create sparks and potentially cause an explosion. You should never attempt to jumpstart a frozen battery, as doing so can cause it to explode. Remove the dead battery, bring it inside, and allow it to thaw before attempting to jumpstart the vehicle.

Can a car from 2003 have jumper cables wrong?
I assumed a car from 2003 would have fuses to prevent totaling your car by connecting jumper cables wrong but the mechanic said otherwise. Is there any reason I shouldn’t call it a loss and junk the car?
