Cigarette Lighter

[Deleted member 478]

On those 12v cigarette lighter thingies, which is the positive and negative connection? Someone said last night that the point in the centre is the positive and the springie things on the side are the negative.

Thanks in advance.

Soldering iron won't mind usually, but yes centre pos

Centre is positive. Because the outside, in a car application, is the negative return, through the bodywork, or through a wire connected to the bodywork/chassis etc.

A lot of appliances don't mind what polarity they have but some get very upset. I plugged in my phone charger on a friend's boat using a portable socket with crocodile clips. It got the wrong polarity and fried the charger.

Quite right.
I always found a 'Zippo' more reliable as well.

OK, OK, What\'s the deal?

There is NO WAY that a dude like you doesn't already know the answer to this one.

they're a bit crap for rope-fixing tho, and not as good as the 220v rope-cutting/ melting contraption which is ace even for 2 inches diamter rope hur hur and verty satisfying too.
