Dead short in the battery. Battery can explode and damage can be done to the electronics in the vehicle.

On any car, switching the battery hookups will most likely fry your battery.



Nothing happens to the vehicle if you connect the negative side first.But is is safer to connect the positive side first. Reason If the negative side is already connected and you put the positive side on you take a chance of touching a part of the body or radiator with your wrench while tightening it, causing the positive side to ground out. If your negative side is not connected yet and you touch the wrench to the body while tighting the positive side nothing will happen. So installing the positive side first reduces the chance of shorting the battery out which could cause the battery to explode.


It may destroy the battery or it may just blow the main fuse or it may do other damage. No way of knowing for sure what will happen.


Nothing. An auto battery system is 12V DC. If both terminals aren't in the loop (positive through the current path and back to negative) nothing happens.


Nothing will happen. There has to be a complete a circuit for the battery to function thus allowing for the flow of electricity.


If you are referring to using a volt meter then you will just get a negative reading on most modern digital meters. If you are using an old analogue meter you may get no reading.


It will throw sparks, melt a spot in the wrench at the point of contact and if it should stick, drain the battery and very likely ruin it. You do this just to check if there is juice in the battery and just for a second.


We hooked up the battery wrong , positive to negative and negative to positive and the motor still turned over but would noy start. Why did this happen ? This is a 1999 gas golf cart ez go.


Nothing. The reason a circuit works is that there is an imbalance between the positive and negative (cathode and anode) ends of the battery. two positive ends wouldn't move anything.


Depends on what kind of battery you lick. If you lick a D, C, AA or AAA battery, nothing will happen because your tongue won't touch both positive and negative terminals. However, if you lick a 4.5-Volt or a 9-Volt battery so that your tongue touches both positive and negative terminals, you'll feel a slight unpleasant harmless shock.


The word "negative" really means opposite so you get a positive.


To verify correct wiring you should have: Battery 1 Positive, to Battery 2 Negative, and Battery 1 Negative to Battery 2 Positive is series wiring, combining the voltage rating of both of the batteries. I suggest adding a "Battery Cut-Off Switch" in the circuit. Some slight arcing can happen if you drag the connectors together.Try doing it outside your vehicle and use a multimeter set to DC volts and test for 22+ volts.



as direction of current reverses it is shown in form of positive and negative cycles


When you divide or multiply positive and negative numbers, you first do the division or multiplication as normal. The next step is to assess whether or not the answer will be negative or positive. If the two numbers of the question were the same (negative and negative or positive and positive) then the answer will be positive. If the two numbers in the question were different (one negative and one positive) then the answer will be negative. Thus, if you divide a negative number by a positive number, the result will be the same as normal division, but the answer will be negative.


The answer depends on how many negative integers you divide by.


No, it can't happen. if one of the parents or both are +, the child will be Positive. I don't know if 2 negatives can have a positive. But i do know that if one of the parents is positive and the other is negative, you can have a either a positive or negative child. (I have twins, one is negative and the other is positive.)




Either the voltage will increase or just the amperage will, depending on how the battery is connected.

It will not fit in the space provided or the posts may be reversed. As long as you connect the positive and negative terminals correctly it will function as any battery should. Just make sure you do not buy the wrong battery.
