yes if one of the wires was getting an earth from the alternator cover or rubbing off the engine the battery light is really an alternator light warning you that the alternator is not charging the battery
Your alternator is defective and not recharging the battery. Have the alternator checked.
When it is no longer able to keep the system charged. Starting with 2001 model, when the car is started, if you see either the battery warning or the battery along with the brakes warnings on, or intermittently flashing on, you need to have your alternator checked. Otherwise, its fine.
The alternator switches off
check the alternator. Use a digital multimeter and with engine running you should have 13-14 volts at the battery. If less than 12.5 Alternator is not charging Also check the amperage the alternator is putting out.
Sounds to be alternator. Take somewhere to have the charging system tested.
Could be the alternator is not charing correctly.
It normally means the alternator is not putting out enough voltage to keep the battery charged and is defective. Can be a loose alternator belt also.
Not all the time. The alternator warning circuit wiring to the instrument panel could be grounded
It's alternator time.
That is the charging system warning light. If it stays on or flickers it means the alternator is not outputting enough voltage to keep the battery charged. With a digital volt meter you should read from 13.5 to 15.5 volts at the battery with the engine running. If not the alternator or the voltage regulator is defective. The voltage regulator is more than likely built into the alternator.
There are several signs that an alternator is going bad. A few signs are dim lights, smell, warning lights, and a dead battery.
If your battery is not charging properly the charging system warning light ( located just to the right of the " F " on your fuel gauge ) will light up . It is the picture of a battery
Have your battery tested first, if it is good most likely it is a bad alternator, have that tested as well
Check your battery connections. Also take your car to an auto parts store and have your alternator checked.
There is a battery light above the engine temperature gauge
The alternator is either over or under charging.
The charging warning light should automatically reset if the battery is disconnected. Check the battery cables and ensure they are properly connected. Also check the alternator connections. If the light is still on there may be a problem with the new alternator.
FYI - I had a bad alternator. Apparently, a failed alternator may/can/will cause the battery AND brake warning lamps to come on. Alternator has been replaced, and all warning lamps cleared.
There is no reset for the battery (charging system) warning light. It is on because there is a problem. Once you repair the problem the light will go out. More than likely the alternator has failed.
Some vehicles have an external voltage regulator which also controls the warning lamp circuit, some vehicles have a warning lamp relay and others may operate through a computor, all of which require a signal from the alternator. You either have a faulty regulator/relay/computor, A broken signal wire from alternator, alternator is incorrectly wired or a faulty/incorrect type of alternator
It is important to note that it takes a lot of battery power for the vehicle to run. The signs of a bad alternator includes dim light, warning light, weak or dead battery, and weird smell.
Check to see if the alternator is working Connect a voltmeter to battery: Without engine running reading should be about 12.8 With engine running reading should be 13.8-14.2 If not bad alternator
Probably the alternator. Have it checked if it is charging.
I obviously means that there is something wrong with the alternator or battery. When both lights are on 80 percent of the time its the alternator. Either your belt fell off or your alternator went bad.
