Jump-starting a car isn’t wizardry, but do it wrong and you’ll be shopping for electronics instead of coffee.
Park the donor close, switch both ignitions off, then connect red to the flat battery’s +, red to the donor +, black to the donor −, and black to a clean metal earth on the dead car (not its battery).
Start the donor, let it idle for a minute, then try the flat car; if it fires, leave them connected another couple of minutes to build charge.
Remove the leads in reverse order, don’t let the clamps touch, and drive 20–30 minutes to top up.
If it dies again, the battery or alternator is likely cactus—get it tested before you relive the same sad morning tomorrow.
