WOO HOO!!!
Right, ordered two of the beggers...
Knowing me.. I MIGHT screw something up, so I will just whip the positive off the battery, just to be sure. 30 second thing to do, in order to save a load of pain!
Thanks guys!
No probs.
ps, its safer and easier to just remove the -ve terminal. Does exactly the same thing but stops the possibility of you shorting out your spanner on something if you were taking the +ve off.
