jumping a car with leads Page 8714

Jump-starting a car with leads is simple, just don’t let the clamps kiss like star-crossed tasers.

Park close, ignition off; red to the dead battery’s +, red to the donor’s +, black to the donor’s −, and black to a clean, unpainted metal point on the dead car away from the battery.

Start the donor, let it idle for a minute, then start the stricken car; remove the leads in reverse order and don’t let the clamps touch anything they shouldn’t.

If it still wheezes or dies again, the battery or alternator may be cactus—drive 20–30 minutes to recharge or get it tested. Never jump hybrids/EVs or any swollen/leaking battery; follow the owner’s manual or call roadside assist.
