Why did I accidentally touch positive battery terminal?

I wanted to make sure the connections were tight on my battery and I started to tighten the positive terminal with the little wrench included in the toolkit and as I was making sure the little bolt was tight, LOTS of sparks flew (and crackling) and it scared the hell out of me. The negative terminal was connected as well at the time this happened.

Do you disconnect positive terminal or negative terminal?

Disconnecting either cable works. The reason they say to disconnect the negative and not the positive is because while taking the positive connection off with a wrench if you happen to touch anything with the wrench while it’s on the positive terminal it can arc and be dangerous. If you travel a lot I would suggest something like a Battery Tender.

When to disconnect battery to prevent drain positive terminal?

To double up on the battery tender. Keep in mind the battery WILL self-discharge even with nothing connected to it. Always disconnect the negative first and reconnect the negative last. Why? What happens if your wrench strikes the chassis?

What makes them battery wrenches ( positive battery terminal )?

What makes them battery wrenches? 95% of the wrench is wrapped in a heavy layer of electrical tape and only the wrench jaws are exposed. Can’t even count the number of times I’ve seen guys short the positive terminal to ground. Plasti-dip works great too, but I’m too cheap to pay 8 bucks for a can of that.

What causes battery to arc over negative terminal?

(2) dirty connections to the terminal. (3) loose connections to the terminal. (4) a higher electrical potential that is close enough to the negative terminal to allow it to arc over. can’t think of any other reasons.

What should I do if my negative battery terminal melts?

Fortunately, the solutions are usually simple as well. Check all cables connected to both the positive and negative battery terminals. This would include the main power cable from the starter to the positive terminal and the ground cable from the negative terminal.

What happens when a wrench touches both battery terminals?

Wrench touched both battery terminals, sparks, now ignition is dead. HELP! Wrench touched both battery terminals, sparks, now ignition is dead. HELP! I installed a new primary battery in my 2004 236 Sunesta which I have done many times.

What happens when you touch a DC terminal?

Touching a single terminal only completes a circuit if the other terminal and you are in contact via the ground. Most people will get a tingle at around 50v DC. AC voltages peak at roughly 40% higher than the rated voltage, so can be felt earlier. It gets dangerous at around 100v depending on other factors (like your resistance to ground)

Is it safe to touch more than one terminal?

Touching only ONE terminal w/o touching (something that’s connected to the) other terminal is generally safe. Normal skin resistance is too high to be overcome by regular battery voltages, so nothing will happen anyhow. Have you been hacked? 80% of emails online have been exposed in data leaks.

What happens if you touch the positive battery wire?

I accidentally touched the positive battery wire to the negative post on the new battery, and the wire smoked a little. I went on to connect the wires to the correct posts, tightened the terminals, and now the truck won’t start, it won’t do anything. A few mechanics have said it was a fuse, but all of the fuses seem to be ok.

What happens if you touch the negative terminal?

It depends on the voltage of the battery, and if the negative terminal is grounded. Touching a single terminal only completes a circuit if the other terminal and you are in contact via the ground. Most people will get a tingle at around 50v DC.

What happens if you touch a car battery?

Car batteries are dangerous in other ways but not as a shock hazard. They are capable of causing burns in the event of a short circuit. They can explode due to hydrogen gas buildup. They can cause chemical burns if you contact the acid contained internally. , I studied electronics in college.

Can you move the battery from one car to another?

There are many battery configurations in regards to terminal position and post size and shape. You could extend positive lead to reach the terminal but it is not worth it as you want to keep moving battery from one car to another. Like the other bloke said get a battery charger. yeah, forget moving the battery all the time…

Can you hook up a 12V charger to a battery terminal?

Get a battery charger.. or hook some other 12V device up to it occasionally. There are many battery configurations in regards to terminal position and post size and shape. You could extend positive lead to reach the terminal but it is not worth it as you want to keep moving battery from one car to another.

What does it mean when you cross battery terminals?

Crossed Battery Terminals – BoneHeaded!! Ok, This is totally emabarassing, I crossed the battery terminals and sparks flew everywhere! It didn’t dawn on me that crossing the battery terminals was the problem when the sparks flew, so I tried it again and got it not to spark.

What happens when you hook up a car battery backwards?

When they put installed the battery, they hooked it up backwards and blew the main fuse. When the main fuse was replaced and I was driving off I noticed that the charging light was on, and the radio/clock was not working. Taking it back, they confirmed that the alternator was dead and replaced it (with me paying for it).
