Defective voltage regulator.
A weak battery, loose/broken wires making a short, defective sensors that monitor what the gauges are displaying
COmputer, loose battery, defective battery/volt amps or loose wiring harness/ wires grounding out somewhere
Malfunction in the charging system. Most obvious cause is a defective alternator.
Dead battery, defective starter or ignition switch. Loose connection.
Dead battery, bad starter, or defective ignition switch.
There are many sensor in today's vehicles, none of which would cause that. I suspect you have a charging system failure possibly a bad alternator.
Either the battery is defective and has a dead cell or something is on which is pulling power from the battery every night.
Dead cell in the battery. A light on anywhere on the vehicle. A relay that is stuck. Defective alternator.
No, the battery light comes on when there is a problem with the charging system. More than likely the alternator is defective.
Do you mean charge by the vehicle running....or do you mean take a charge from a Bench charger? if its in the vehicle it could mean that either the battery/battery connection/cables, a faulty ground, or the alternator is defective. If its on a bench charger then the battery has a dead cell or is defective and needs replacing.
One possible cause is a defective alternator, Have the charging system checked.
