settle an argument!!

To safely charge a battery in situe, I would simply remove the positive lead for the car first.

Stories of blowing stuff up when jumping are usually the result of bad lead positioning.  You shouldn't really connect both batteries directly together.  The safer way to do it is Positive to Positive, and the negative from the supply car should be connected to the body of the flat car, not the battery.

Yup, that's how I've always done it.

exactly what i did

What difference does it make if you put the negative to a ground on the chassis or the battery? The chassis is grounded to the battery, making a circuit. It wont make a difference where you put it.

Electrically, there isn't any difference.

Not sure what difference this makes either...the body to the negative will be more or less 0 ohms, essentially same point

usally put jump lead on to some engine bracket.

some cars really really hate being bump started    pudgits and sh!torens are famous for that one.

not met anything yet that wont jump start some arnt so straight forward tho, usally fnd it better to connect them up and leave 10 mins  dont even need the car doing the jumping to be running

[Ant1981]

And with the cars not liking being jump started, can't see the difference in connecting jump leads to the battery and starting the car, as all the car will see is a 12v battery that'll start it.

So what he's saying is that every time the battery has to be changed, the electrics and the gearbox have to be changed/repaired? 

It is a vauxhall................
