Hello; You have corrected the alternator and have checked it for output, I presume.. Installed in the vehicle your reading at the battery should be betweebn 13.6v to 14.2 volts. If either end of the range is exceeded, the warning kamp will come on. If possible use a obd2 scan tool to turn the light off. If the problem still exists, the light will come back on after a few drive cycles. Do not discount the battery as it is also part of the charging system. Check cpnnectons and if possible, water/fluid level
When alt is charging, Keep in mind, yhe lower the voltage the higher the amps output. 12 volts is full output of alt and will cause componant dsmage. Gooj luck-Ned

Have an OBII scan done and reset dash lights with same tool/scanner. Autozone, Advance or any good parts store or shop can do it for you and most will do it FREE

I have a 2000 honda civic dx 1.6l and when i drive down the road and come to a stop all my dash lights and head lights flicker

Sounds like a bad diode in the voltage regulator. This will cause fluctuations in the DC voltage. The faster the engine goes, to less noticeable the fluctuations will appear. Have the alternator/regulator checked and serviced as necessary.

I have a 2004 ford focus battery light keeps going on and off dash lights go dim then bright I replaced alternator and battery 6 months ago any suggestions?

If this happening at any engine or vehicle speed, look for damaged wiring harnesses, expecially those that appear to be tight. Those runnig near an engine pulley, or over a pinch weld. and near steering components. Check engine ground cable to chassis, and check engine mounts for wear.

If no damage is found, does the light dimming correspond to the AC compressor engaging? You might have a failing AC bearing on the pulley. It would not hurt too release the serpentine belt to check the condition of the AC ulley bearing for noise, for excess radial play or other indication of pending failure such as difficulty in rotating the pulley.

If that checks out- load test the alternator (the regulator is part of it so it is tested at the same time)

2004 chevy tahoe battery not charging light is on

here is how i solve my battery/charging issues:
1. as preventative maint. i purchase a new battery for my vehicle every 5 years regardless.
2. when i have a battery issue i call around to auto part stores to see who has the equipment to test the battery to determine if the battery is the problem.
3. if not the battery, often times the regulator (usually internal in the alternator) is the problem, an auto store may have the tester for this, again call ahead.
4. if its the internal regulator, you can have the alternator rebuilt or purchase a new one, basically a push either way.

good luck.

Charge light was on and alternator was overcharging. had alt. rebuilt and new voltage reguator, not charging now. only getting 2 to 3 volts are the charge fuse beside battery. new voltage reg is electronic...

There is a fuse under the dash that is the same one that operates the fuel gauge, if it blows the alternator wont charge. If the fuses are good I would take the alternator off and get it tested. Hopefully the rebuilder will warranty it. I would also make sure the new regulator is compatible with the old type regulator system. Most large auto parts stores can test alternators, and they normally do it free.

I have a 2001 Honda Civic, the dash lights and head lights flicker, pulsating but staying on. The battery is charged and there doesn't appear to be a short or loose ground wire? Could this be the...

Bad alternator/voltage regulator or your car may have a body ground sensor, it will need to be checked with a computer to get this one diagnosed properly. Headlight switch may be the problem itself, lots of moving components in them now days.

#14 fuse in a 1991 honda civic si keeps blowing......labeled alternator/solenoid. Can someone please tell me what feeds this fuse to make it keep blowing.

That leaves only two probablities: 1) a possible short in the wiring to the alternator, or 2) the alternator itself, particularly the voltage regulator inside it. Voltage regulators can be changed, but virtually nobody does that. Since you have to take the alternator off to do it, most people simply replace the alternator as a unit.
I would take a good look at the wiring to see if there are any worn-bare places. I doubt that that's the problem, but it could be. There is also a fusible link (flat single piece of metal which melts under too high a charge) in SOME models of your car in the wire that goes from the starter solenoid to the alternator (I doubt that your car has one since it probably would have blown rather than the fuse you indicated).
Next (you won't be delighted by this) change the alternator. It might look difficult, but if you take your time and you have or can borrow the appropriate wrenches, you can do it.
Here's how:
Detach the negative cable from the battery.
Mark and detach all of the connectors from the alternator (do not trust your memory).
Test the tension of the drive belt (you’ll have to get it roughly back to that tension when you change the alternator)
Loosen the alternator adjusting bolt (the one that goes through the oblong hole so you can tighten the alternator against the belt).
Loosen the pivot bolt (the only other bolt holding the alternator in place).
Detach the drive belt (push the alternator away from it, but do not take the belt off, unless you have a diagram indicating how it goes on).
Remove the adjusting bolt and the pivot bolt, then the alternator should be free.
Take the alternator with you when you go to get a replacement (some place like Autozone would be okay. Ask for a rebuilt alternator (they are cheaper and usually reliable).
Make sure the rebuilt alternator has the same connections as the old one. Look at it carefully.
Alternators usually don’t come with the pulley. Have them put your old pulley on the alternator you are buying.
Take it home, put it in, tension the belt to approximately where it was. Start the car.
I hope that this helps you.
