What happens if my battery cable is loose?
A loose battery terminal affects the flow of electricity. There is less power going to the electrical systems and the vehicle will not start or start sluggishly. Also, a loose battery terminal causes the car's electrical components like navigation, car lights, and audio among others to dim or fail completely.
Can loose battery cables cause a car?
The primary symptoms of loose battery cables are the complete failure to start and visible signs of power loss during driving. The first symptom is shared with the battery and the starter, while the second can be caused by a faulty alternator.
Can a loose battery connection lead to alternator failure?
There are also external wire connections to the alternator that energize the rotor and carry current from the field coils to the electrical system. If any of the connections are bad (loose, corroded or broken), it can disrupt the alternator's current output.
Will disconnecting car battery harm computer?
Disconnecting your car battery will not cause any permanent damage to your computer or ECU (electronic control unit), but it can have some adverse effects. Those include canceling your preset radio stations, forgetting learned shift points, and your car's ideal fuel/air mixture.
What happens if you connect the negative terminal first?
It is only a safety issue. If you first connect the negative cable, then when you connect the positive cable there is a chance the wrench will complete a circuit between the battery and the chassis of the car. This will at a minimum generate a spark, but that spark could eject molten metal toward you causing injury.
What connects to a car battery terminal?
There are two cables that connect to your battery. The positive cable's end connector is often either painted red or has a red plastic clip attached to it. It runs to the engine's alternator. The second cable is a ground cable, which connects the negative terminal of the battery to the body of the car.
What is the thread size of a side post battery?
General Motors, and other automobile manufacturers, have also begun using side-post battery terminals, which consist of two recessed female 3/8" threads (SAE 3/8-16) into which bolts or various battery terminal adapters are to be attached.
