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 when a battery is hooked up to a negative terminal?
When the battery cables are hooked up with the negative to the positive and positive to the negative terminals, the battery can explode.
What happens if I hook battery cables up backwards?
Battery to Battery When the battery cables are hooked up with the negative to the positive and positive to the negative terminals, the battery can explode. A battery charger that is being used to charge a dead battery will be damaged if the positive and negative cables are hooked up incorrectly.
Can a battery be charged with a negative charge?
Remember, a completely discharged battery is nothing more than an empty vessel. In order to gain a negative charge, it would then necessitate being hooked up backwards, and charged that way.
What happens when jumper cables are reversed on a battery?
Damage to the Batteries. Connecting the positive terminal of each battery to the negative terminal of the other battery will result in a huge surge of electrical current between the two batteries.
Where is the negative terminal on a car battery?
A car battery’s negative terminal has a cable that runs from it to the frame of the vehicle. This causes the entire frame to act as the negative terminal of the battery.
Remember, a completely discharged battery is nothing more than an empty vessel. In order to gain a negative charge, it would then necessitate being hooked up backwards, and charged that way.
Why does a dead battery reverse its polarity?
So with your batteries in parallel, one battery was probably drained further than the other. Both were used up but one went dead first. Discharged battery plates are essentially neutral, so when both batteries were recharged together, the plates in the dead battery swapped chemistries, and consequently polarity.
What’s the difference between positive and negative jumper cables?
The positive jumper cable should attach both batteries’ positive poles while the negative jumper cable attaches the two negative battery poles.
Why do the positive and negative wires spark when touched?
This spark is caused by the initial current flow when the voltage difference between the two points is bridged together. You will also have a spark when the two points disconnect as the current is interrupted.
What happens if you touch jumper cables together?
What happens if you touch jumper cables together? When the jumper cables are hooked up to a battery, touching the cable ends together can create sparks. In some cases, the sparks can ignite the hydrogen gas escaping from the battery, causing an explosion.

Can a negative battery be attached before a positive lead?
Actually you need to turn the key to Position 2 prior to reconnecting the battery. Also you attach the positive lead first, then the negative. Failure to follow this procedure could damage some of the electronic components, the CCM is the usual suspect. Its all part of the OEM-specified procedures documented in VADIS/VIDA.
How do you remove a positive terminal cable from a computer?
Remove the positive terminal cable from the battery using your pliers or wrench. Go to your fuse box in your car, and look at the diagram. Select the fuse that is labeled “ECM” and remove this fuse. Keep the car disconnected like this for two to three minutes to clear the computer’s memory.
Can a jumper cable be connected to a dead battery?
Connect the other end of the black (negative) jumper cable to a metal part of the dead car that is unpainted, as far from the battery as the cable will reach. This will ground the circuit and help prevent sparking. Connecting it to the dead battery carries a risk of the battery exploding.

What happens if you disconnect a negative cable on a boat?
If the terminal of the negative cable you disconnected to perform maintenance on your boat were to come in accidental contact with the battery’s negative post, the boat’s circuits would remain charged as if you had never disconnected the battery.
What happens if two battery cables touch a boat?
The charge will flow from the positive post of the battery to the negative post of the battery. You will have created a short circuit that isolates the boat’s circuitry, because electricity chooses the shortest path between the positive and the negative.
Where are the positive and negative battery terminals?
)The positive cables were on the positive battery terminal (loosely, not tight) and the ground cable was not connected. Of course there were little burn like spots on the wrench where it touched the terminals but I figured no harm no foul. Now when I turn on my ignition, nothing, dead, no gauges, nada.
What happens when you touch both terminals of ECU?
Touching both the positive and negative will discharge what ever remaining power is in the ECU. Even after your battery is removed, touching the 2 terminals together (with out even having any source of power) you will even create a small spark, draining what’s left.
