Alternator is defective or the battery has a dead cell and will not take a charge. Check the voltage at the battery with the engine running. You should have between 13.5-16 volts. Anything less and your alternator is bad.
Depends on if it drained while you were driving or ran down while it was parked overnight. If the battery runs down while you're driving the vehicle then more than likely the alternator is defective. If the battery drains while the vehicle is parked then the problem is either a dead cell in the battery or a light is on somewhere on the vehicle. Could be a under hood light, trunk, glovebox, dome, or even the brake lights. It can also be a relay that is stuck.
It is a meter with a high wattage resistor connected parallel with the meter that drains power from the battery while it is measuring the voltage it is used to test the condition of the battery if the condition is good there will not be a large voltage drop while testing the battery
Your battery is weak, or your your alternator is not charging battery.
Alternator is defective or battery has a dead cell.
It can be a dead cell in the battery which means the battery must be replaced. It can also be a light is on somewhere on the vehicle or you have a stuck relay.
check battery cables at battery may be lose.
Not likely.
yes
Sounds like the alternator isn't working at all. Have it checked. Good Luck!!
I have seen the doors with inches of water inside because the drains were plugged up. You could hear the water sloshing back and forth while driving.
The alternator died first and drained your battery shortly thereafter.
Your car lost power while you were driving and it will not start now because the battery is depleted.
