What could cause the battery indicator light to remain on after a new alternator has been installed?

You don't say what kind of car so make sure all of the wires were hooked up correctly.

Sometimes an alternator with a weak diode(s)can test out fine, but can still trigger the light. I believe the problem is in your alternator. Good luck.

Rather than assume, why not check the alternator? If an alternator is not functioning properly, the battery can only remain fully charged if the alternator replaces the electrical energy that has been used. Test the system to determine if there is an electrical drain, but start with the alternator first.

just bcuz you brought it new doesn't mean it can not be defective take it back to the seller and have it checked this problem happens very often because alternators are not new anymore they are remain parts

In ultrapure water the indicator remain unchanged.

Sure you can. But it would be much easier to purchase a compacitor which acts like a battery in that it stores power and uses that to power what is connected to it. This also saves the alternator

Sometimes a weak diode within the alternator can cause this. Your alternator may test out fine but have it checked anyway. I hope this helps you. Mark get your alternator checked out as it sounds to me like its on the way out

Make the sure belt has tension in it and it's turning the alternator pulley. When the car is started, remove one of the positive battery terminals (carefully of course and don't let it touch any other metal, wrap it in a rag). If the car continues to run, then the alternator and volt regulator are doing their job. The alternator's primary function is to recharge the battery after starting the car, then to run the vehicle's entire electrical system, which includes the ignition system. If the car dies after you remove the battery cable, then most likely the alternator is working. Go to Auto Zone, they'll check the entire system for you for nothing, otherwise give this a try. The car may not remain running when a battery terminal is removed. An alternator uses coils instead of permanent magnets for their stator. In order for their to be a magnetic field in the stator, it requires some current to be passed through the coils (A generator uses permanent magnets, so it already has a magnetic field in it without needing any external current). This current comes from the battery and if the battery is removed, the alternator will not put out any current, ultimately causing the car to stall out. However, if the engine uses a generator, it would remain running. Consequently, an alternator will not charge a completely dead battery.

You're describing a common problem. Many times a relay, such as the AC relay, will fail to turn off when the key is off. When that happens the device controlled by the relay, such as the AC clutch, will remain engaged and drain the battery.

The life of the battery. You never have to change it.

Does it squeal? A loose serpentine/alternator belt can do that. Also a bad laternator,or poor/loose connections tothe alternator. You need electricity to fire your sparkplugs, and without that your car will stall out. Could also be a short circuit somewhere draining your battery faster than the alternator can keep up with.

on QX4 1997 i got on begining check engine and ABS after i replaced alternator and the battery light goes off and after couple days that come back, i suspected electrical problems

it will remain neutral as products of neutralisation are salts and water

The function of the Magic Eye® state of charge battery indicator is based on the specific gravity of the sulfuric acid or electrolyte. When a battery is charging, the change in the density of the acid is a little delayed as compared to the actual state of charge of the battery. However, the battery indicator should show green once the battery is back to 100% state of charge. There may be several reasons as to why it is not showing green: 1. If the battery was allowed to remain in the dis-charged state for a great length of time, the battery may in fact be bad and the battery indicator will not show green because the electrolyte has not reached the proper specific gravity. The specific gravity of the electrolyte is the most accuarate method of measuring state of charge. 2. The acid in the battery is "stratified" meaning that the heavier acid has sunk to the bottom and the lighter water is floating near the top. This happens with batteries that have sat for a long time in the discharged state. Normally, re-charging will stir the electrolyte make it more homogenious. 3. There may be a small piece of battery separator material preventing the green ball from floating up. The best thing to do is gently rock the battery back and forth. This will mix the electrolyte and will most likely free the green ball to float up "IF" the specific gravity of the acid is dense enough. Keep in mind that even though the Magic Eye®is located in only 1 of 6 cells, testing conducted by a major OE car company proved that the battery indicator accurately indicates the state of charge of the entire battery.

You can use an indicator like litmus paper its colour will remain same if the solution is neutralized and also can use universal indicator when you pour a drop of it and it changes its colour to green.

You have electrical problems. Take it to a good garage. My '92 Corsica did that when I put a new bolt on the negative terminal for the battery. I replaced it with the old one and never had the problem again. -xGuiltyFatex = I am not 100% sure its probably your alternator have it checked = = I have a 92 3.1 a few days ago while driving the battery light = and inflatable restrain ( air bag ) lights came on, also the speedometer showed 120 while I was going 50 Km. I pulled into a parking lot and turned off the engine, When I tried to start it did not turn over I boosted the battery, the car started but the battery light remained on. So I changed the alternator, up to now the battery and inflatable restrain lights remain off.

The reason a high beam indicator light might remain on in the dash of a 2005 Nissan Sentra might be a short in the wiring for the high beam headlights. It could also mean a short in the wiring of the steering wheel where the high beam switch is located.

User Avatar

Maybe you'd like to explain what you mean. I can't believe you actually want your headlights to remain on all the time - you'd flatten the battery.

Your question must be more detailed. Did you mean hardwares that can't be removed ? Motherboard and CPU, power supply... but your question should be better explained. They remain installed until they have a breakdown, of course.
