What happens when a battery ground post loosens?
A battery ground post can loosen over time. When the ground or positive posts become loose, this can cause problems such as a battery that won’t start or battery fluctuations that cause the vehicle light to flicker.
Can a bad ground strap be a battery problem?
If you are having electrical problems with your car, the problem could be a bad ground strap. The ground strap is connected to the car battery’s negative terminal. It is also called the negative battery cable. Almost all of the car’s electrical components are connected to this cable.
Can a bad ground wire cause a battery to die?

What should I do if my battery ground is not working?
If your accessory still doesn’t work properly after redoing the grounds, you will need a voltmeter or multimeter to trace the wiring. Set the voltmeter to read ohms (resistance) and probe the battery’s negative stud and ground connection on the accessory (the ground terminal on an amp, for example).
