Bad Alternator

It’s simple to look at the capacity of the alternator with a multimeter. The voltage ought to be between 13.6 volts and 14.6 volts. Assuming the voltage is under 12 volts, we set the battery light off and you’ll probably have to supplant the alternator.

Bad Battery Cable

Battery links convey the power from the battery to the actual vehicle. Assuming the power can’t get to the vehicle, it’s unusable, so these links are little yet strong.

Bad Ground Strap

A ground lash, or ground wire, finishes the circuits of various parts around the vehicle so power can stream as it ought to. Assuming that the ground lash is harmed or withdrawn, the battery will most likely not charge.

Faulty Wiring

There are a lot of wires engaged with the electric charging framework, so, if any of these are broken or disengaged, the battery caution light might come on. Wires commonly break around the connectors instead of advancing up the wiring bridle. The wires and connectors might be solid and fragile with age.
