Jump starting procedure
Discussion
I'm contemplating a jump between two modern cars (to avoid having to wait hours on the charger for the car I need to shift!)
As it's not something I've ever needed to do before I checked the procedure and everyone says to connect the leads with ignition off on both cars, leave for a bit, then start, run for a while, then turn off and disconnect.
Anyone know why it isn't "leave good car running and connect, thus allowing the alternator to take the load instead of the battery, then disconnect with engines running so you aren't trying to restart with a still quite flat battery"? Either way you are holding energised leads with somewhere between 12 and 15 volts, so can't be for personal safety.
As it's connecting the two batteries in parallel, I don't see how it protects anything to do it with engine off instead of on. Has anyone fried a car through connecting/disconnecting leads with the engine running?

The good news is that in the time it took to post this, then go and buy jump leads, my charger stuffed enough electrons into the battery that the car started just fine.
Now I've got the leads, I think if it happens again and I don't want to wait for the charger I'll jump from a known good battery, disconnected from its car.
