When you connect the jump leads connect the red ones to the + terminal first (one on each battery) then connect the black ones carefully to the the - terminals on the battery. When you remove it, reverse the order, black first, red second. Only do one colour at a time.
If you cross them then the chances are the battery cells may explode leaving you at best severly shocked and your car severly knackered.

Actually Rachel probably nothing would happen as soon as you connect the last connection you will get lots of sparks and if you ignore them and put it on anyway you won't be able to start the car. You know what you shouldn't do especially with newer cars is having the good car running when you jump. You don't need to have the car running because if you do when you attempt to start the dead car it will pull a lot of juice from the electrical of the running car if the car is not running it just pulls juice from the battery and so if you cross them up it won't cause much damage.

Assuming it was computerized, you'd blow the computers, (and wouldn't do your battery a heck of a lot of good, either) because you're basically giving the car a massive short-circuit. But if you were lucky, the fusible link in the car's wiring harness would break, preventing any substantial damage. Even the fusible link breaking probably wouldn't save your alternator, starter or fuse box.
In earlier cars, jumping the battery the wrong way can fry the wiring harness.

The most common damage is to ruin one or both batteries. Beyond that, it will depend on the year of the vehicles. Older vehicles are less susceptible to electronic damage. Newer vehicles could have module damage throughout the vehicle including charging system.

Lots of sparks and eventually the leads will catch fire damaging the batteries and probably the whole electrical systems,

It would not damage the car per se, but the jump leads would melt. Potentially, it would do more damage to you.

Firstly u'll get a bloody big spark from the jump leads/battery. The worst outcome is that u'll completely destroy the battery you're attempting to revive.

Prob blow a bunch of fuse and create some sparks
My husband did this on my 94 Mustang, the sparks gave him the clue something wasn't right. All the fuses blew.

You'd fry both the batteries, the leads and not to mention anyone stood too close.Battery burns hurt and take months to go
