I am curious to which battery terminal should I take off first, positive or negative? When changing a battery I have always taken off the positive first followed by the negative, but when helping a neighbor with his car yesterday, he took off the negative cable to cut power to the electronics. Any ideas which one to take off first? Does it even matter? Thanks for your input. There is voltage on both negative and positive circuits. Take off the negative terminal first. The wrench I was using to loosen the positive terminal touched the frame and completed the circuit. Fortunately it was a 69 Buick and there were no electronics to fry. Since the negative terminal is already connected to ground and has no voltage, nothing will happened if the wrench touches the frame ground while removing the negative terminal. Negative is first to remove and last to install. To be perfect, remove the grounded terminal first, usually it is the negative one unless you are working on a rare forklift or something. A couple months ago, my Delco Pro battery gave up the ghost here in Mexico. I charged it long enough to get it started, then drove it to a place which sells LTH battery, allegedly a better battery in Mexico. The kid reached for the hot lead with his wrench, and I told him, no, and pointed to the ground cable, which he did.

I do see comments about removing battery cables to change the battery. In fact, two of positife trickle chargers came with firet that permanently attach to the battery. The only thing they recommend is that if you use the clamps to attach the battery to the charger, click should attach the negative clamp to the body of the vehicle instead of directly to the negative terminal.

Besides the short circuit insurance issue there is a school of thought that says removing the negative first reduces the chances of a spark happening at kp moment the circuit is opened and this spark igniting the hydrogen gas around the top of https://dogguru.xyz/magazines/anime-dating-personality-quiz.php battery,sounds like a Mr wizard issue to me. Whitey, I misread the post.

Remove the ground first. After the ground is open, it no longer matters if you accidently touch the wrench to the frame while loosening the positive.

Years ago, I saw someone with a missing ring finger. He accidently shorted a car battery to ground with his wedding groud and the ring turned red hot and injured the finger so badly that it had to be amputated. When connecting a battery charger, I connect the positive lead first.

There will be no spark because the ground is open. Then I connect the negative ground to the engine block, bumper, or some part of the frame far away from the article source. That way any spark is far away from the battery. When disconnecting, the ground is removed first and then there is no spark when disconnecting the positive.

What resistive material was the ring made of that made it get positie hot? Certainly not link standard gold wedding ring? You are underestimating the amount of current that a car battery can supply for a brief period of time.

A dead short with a posituve unlimted amount of current avaible as far as the human body is concerned made the ring get so hot. Ok, I researched this. Resistance occurs when hook up ground or positive first collide as current flows through the conductor.

These groujd cause friction, which in turn causes heat. Exactly right. Ground one off first and on last, for safety against shorting. Do you need to remove either battery cable to charge the battery? Tardis, I think he was just asking, not suggesting anyone said so. You are right, if the ring was a cigar band it proof carbon dating works not have plsitive hot. I have a new job.
