What are the symptoms of a failing battery cable?
That is why the first symptom that you will likely notice when it comes to a failing battery cable will be problems getting the car started. Specifically what you may notice is that the car is cranking – in other words, the engine is turning over, trying to get started – but it takes much longer than it used to.
Do you have to relearn idle when a battery is disconnected?
Many newer cars with powertrain control modules (PCMs) have to relearn engine idle after a battery is disconnected. The removal of electrical power from the engine erases idle memory from the PCM, the computer where it is stored.
Can a bad battery cable cause a car to start?
If the cables have any sort of problem, it may interfere with their ability to conduct power. Starting a vehicle takes a considerable amount of cranking power, so any problems with the cables that hinder their ability to conduct power can lead to problems getting the vehicle started.
Why are no power to vehicle battery cables important?
No power to vehicle Battery cables are an important piece of any electrical system, as they are what directly connects the battery to vehicle’s electronic system. They are usually made of heavy gauge wire covered in heavy duty insulation due to the high amount of current and power that flows through them.

What should I do if my car battery goes wrong?
When your vehicle starts to go wrong, it is of course natural enough that you will want to fix it quickly and, if possible, cheaply.

Can a loose battery cable cause a car to go off?
Typically if your battery is draining after sitting for a while there is something drawing a charge from the battery while the car is off. But there could also be a problem not allowing the car battery to be charged up all the way. This sort of problem could be due to a loose battery cable but it could also mean that your alternator is going out.
Can a negative battery cable be a problem?
Usually, if you have a problem with one of your battery cables it’s going to be a problem with the negative battery cable. Negative battery cables are typically short enough to be connected to the frame of your car somewhere near the battery so they are relatively inexpensive.
Can a loose battery cable drain the battery?
A loose battery cable won’t typically drain a car battery but it can contribute to not allow the battery to charge properly. Typically if your battery is draining after sitting for a while there is something drawing a charge from the battery while the car is off.
