The negative teminal needs to be connected to complete the electrical circuit. Without that none of the electronics in the vehicle will work, including the starter.

What are positive ground cars?
Cars in which the positive terminal of the battery is connected to the chassis. They require specially designed components built for positive ground cars. The usual configuration is a negative ground (the negative battery terminal connected to the car's chassis).
Why most car bodies are attached to the negative terminal of the battery?
The DC electrical system of the car requires a positive and negative electrical conductors for each electrical device. Taking the example of a single lightbulb powered by the car battery, this could require a wire leading from the positive terminal of the battery to one terminal on the lightbulb and a second (return) wire leading from the other terminal on the lightbulb back to the negative terminal on the battery. Two wires are required - a positive and negative. To reduce the quantity of wires required, the negative "wire" is actually the car body. Hence there is a positive wire leading from the positive terminal of the battery to the positive terminal of each electrical device on the car and the negative terminal of each electrical device on the car is connected to the car body (a metal conductor). The body of the car is then connected to the negative terminal of the battery, completing the circuit. There are virtually no return wires. This works as cars use a low voltage (12 V). If they used a higher voltage, this system could result in electric shock from touching the car body.
What side is the negative on a battery in a car?
It will vary from car to car, but the neg is usually black, and has a "-" sign. Normally the positive terminal is larger than the negative terminal.
What meant by one terminal of a car battery said to be connected to ground since it is not really connected to the ground?
'Ground' is an electrical term indicating the return path completing a circuit . ~ See related link below . The negative terminal of a car battery is connected to the chassis of the car. This defines the reference point for measuring voltages in the car. It is possible for the body of the car to be connected to the ground, such as when the car is put on a metal jack. This has no electrical effect, so the body of the car is pretty much equivalent to ground.
How do you reboot a car computer?
Disconnect the negative terminal of the battery Leave it disconnected for an hour. (The amount of time it takes to replace the battery). Reconnect the negative terminal of the battery. This works because a transient (voltage spike, noise) is generated when the terminal is reconnected. This is not necessary when the battery is replaced because the negative terminal is normally the last connected. However, when a car's battery dies in storage for example and is recharged with disconnecting the battery, the car might not start because the computer is not running.
Do you unhook the negative terminal when charging a car?
NO!!!!!!
How do you hook two automotive 12 volt batteries and still get 12 volts?
In parallel. IE: Positive terminal to positive terminal, Negative terminal to negative terminal. Same as boosting a car batery.
What is red color on battery?
The red terminal on a car battery is the positive terminal which feeds electrical current to various devices. The black terminal is the negative, or ground, terminal which is attached to the car frame.
What is negative terminal post?
the post that grounds itself to the body of the car
You Connected the battery to wrong terminal corrected but car is not running right why?
You cross the battery.
How do you find a grounded wire in a car?
is connected to negative pole and to body of car
Which terminal on a car starter do you connect the negative?
To the battery post with the " - " symbol not the one with the " + "
