Why does the battery light stay on after changing the alternator on a Lincoln Navigator?
check the alternator fuse on the main cable that goes from the alternator to the battery. sometimes the alternator shorts out this fuse. it's usually mounted on the right side of the firewall in a plastic cover over .
Indicator light stopping on once you lock car left hand side stays on then flattens battery any ideas?
fit a new indicator column switch
Is my alternator in need of replacing if my '04 Expl XLT instrument panel lights flicker at random while all other electronics seem fine and battery is brand new?
Dashboard Indicator Light If you have an alternator and are using the factory style indicator light on your dashboard, it is a pretty helpful thing. It helps kick-start the alternator into working at idle speeds when you first start the car, and it tells you if the alternator is putting out less voltage than the battery has in it, indicating a problem. The light is connected on one side to the field current system inside the alternator and to a switched ignition power source on the other side. When you turn the key on but have not started the car yet, the field acts as a ground and power flows through the light and out to ground - lighting the bulb so you know it works. Once you start the car, the voltage at the field is powered internally by the output of the alternator. If this value is exactly the same as the battery voltage, then you have the exact same voltage on each side of the indicator light and they balance each other out - kind of alike a tug of war in reverse. If all goes well, the light never comes on, and you drive happily around knowing all is well with your alternator. If the output of the alternator should drop due to a slipping/broken belt or due to certain kinds of electrical faults inside the alternator itself, there will be less voltage on the field side of the light and more voltage on the switched ignition side of the light. The result is that some amount of electricity will flow through the light and into the field and the light will glow proportional to that voltage difference. This is how a slipping belt or an overloaded alternator will cause the light to glow very dimly, while a full-on failure will cause the light to glow very brightly. Note that if you disconnect (or forget to connect) the wire at the alternator, the light will never come on and the alternator may not charge properly. The dashboard indicator light circuit also typically has an extra wire with a calibrated resistance in it. This wire is run in parallel to the indicator light and has about a 10 ohm resistance. It's purpose is to allow slightly more current to flow to the alternator field current system at initial start-up to make sure the alternator begins producing power as soon as the engine starts. About 1 amp total current is flowing to the field current between the light and the resistance wire, with the resistance wire supplying about 3/4 of an amp. This extra resistance wire does not affect the functionality of the indicator light in any way.
What would cause the alternator warning light to come on in a 1979 Chevy Malibu?
Its telling you that for some reason the battery is not charging. Possible cause are: poor or dirty cable connections at the battery posts, bad cables, bad battery. It is also possible that the brushes in your alternator are bad but, the fact that you are getting a light usually indicates the problem is with the battery or cables. For some reason on a GM alternator when the internal regulator in the alternator fails you don't get a light. The only indication you get is that when you turn on the key the battery light doesn't come on. So it is probably not the alternator. Check for corrosion around the battery cables where they connect to the battery. That is most likely the problem. If you have the type that screw into the side of the battery, they may have just worked loose. Good luck
Why does your 1993 z24 cavalier drain the battery?
It may be due to a bad alternator. If the alternator has a bad diode it will draw battery power when the car is off. Another possible draw is the trunk light. The trunk light works with a sensor that is mounted to the curved bar on the left side (drivers side) of the trunk. This sensor sometimes slides out of adjustment and keeps the trunk light on when the trunk is closed.
Can you drive your ford expediton if the battery light is on?

What should i check on my 97 Ford F150 4.6L Triton if battery light don't come on has new alternator and battery but wont charge up the battery?
locate the x fuse in the engine right side test it
Should a cable running to the alternator be live?
Yes This Cable Is Connected To A Group Of Cables That Run To The Battery Positive Side, To Allow The Alternator To Charge The Battery.,Do Not Remove Or Install An Alternator Until You Remove The Ground Terminal From Your Battery.
How do you replace an indicator bulb on a Skoda?
Begin by removing the connector from the back of your VW drivers side indicator light. You can remove the light bulb by pushing it in and turning at the same time. Reverse the process to install your new drivers side indicator light bulb.
How do you tell if the alternator is outon a 1999 kia spehia?
A quick way to tell if there might be a problem with an alternator is to remove the positive side battery cable from the battery while the vehicle is idling. If the engine dies, odds are there is an alternator problem.
