hey sorry to be stupid but i left my lights on, and when this happened before someone put the jump leads differently to how it says in the manual, and so i was jsut wondering how they were supposed to go...

is it red to red and black to black, or my black to earth? thank u sorry i know its stupid

what do you mean black to earth? black on the battery is earth (usually)

look at the signs on the battery

+ = positive
_ = negative

so + - + and _ - _ and you wont go wrong


dont worry if it sparks slightly when you connect the last one, it just means their is a good connection, give them a little shoogle once their on to makesure the connection is good as dirt/grease can give it a bad one.

Makesure they + wires and the _ wires dont touch each other

You could also connect the earth wire on the dead battery car to an engine lift eye or something simmilar

If it doesnt go on the first turn of the key, leave the ignition on and give it 5 mins (dunno what this does but works for me?)

Red to Red FIRST

Then

Black to Black SECOND

Then remove the Black FIRST Once you have started it


Hope that helps ?


Regards Doug .

thank u

nothing seems to be happening... we have left it for a good 5 mins but it still isnt doing anything... the manual says red to red their black to my chassis?

Chassis or straight to your negative battery terminal the BLACK one is the other car running ? .



Regards Doug .

both... it has happened before and with the same leads..... any ideas??

the leads prob pretty thin?

put the earth from the running car to your exhaust manifold or to an engine lifting hook

all i can think is the connections arent good!


try bump starting it, even with a flat battery it could still work, or get someone to tow you while you bump start it.
