Guest BrainFluid Posted January 19, 2007 Seen as its the negative that you should disconnect when working on the car do they put the easy twist off connecting terminal on the positive feed? Weirdos! Share this post Link to post Share on other sites
cybernck 402 1 Cars Posted January 20, 2007 hmm it's negative off when you want to reset the ECU, but i always take a positive off if i'm working on electrics . Share this post Link to post Share on other sites
petert 587 Posted January 20, 2007 I always take the negative off a car battery. That way if a tool accidently branches the positive terminal (or starter, alternator etc.) to earth, it won't cause a big SPARK! Share this post Link to post Share on other sites

cybernck 402 1 Cars Posted January 20, 2007 petert> yeah that's a good point , but i was referring to working on a fuel pump etc. i disconnect positive or both in that case. Share this post Link to post Share on other sites
Sam 4 Posted January 20, 2007 Surely it makes no difference, after all there is no circuit if the negative is off. Share this post Link to post Share on other sites
Jer309GTi 3 Posted January 20, 2007 I always take the negative off a car battery. That way if a tool accidently branches the positive terminal (or starter, alternator etc.) to earth, it won't cause a big SPARK! Thats the way they taught us at college, and for the same reason, disconnect first-reconnect last Share this post Link to post Share on other sites
pug_ham 244 3 Cars Posted January 20, 2007 I always take the negative off a car battery. That way if a tool accidently branches the positive terminal (or starter, alternator etc.) to earth, it won't cause a big SPARK! Thats what they recommend for every job in the Haynes manual; Changing a tyre; 1. Remove battery negative lead. 2. Loosen wheel nuts/ bolts slighty 3. etc... Even changing a fuse I bet. Graham.
