Alternator not charging


Possible short to the starter. I had a similar problem with my '91 mercury capri. I replaced the alternator and battery but the alternator would not charge the battery. My local mechanic spent hours tracking it down, but finally found the problem. Have not had a problem since. Good luck

I put a new battery in and it ran a week and shut down again...


Hi.

The problem is often a defective alternator. Check voltages across battery terminals. When engine is on the voltage must go up from 12.5VDC to 13.5/14.5 VDC. If that does not happen the alternator is defective. If it is more than 14.5VDC the alternator's voltage regulator may be defective. If the alternator is OK the problem may be a short that is draining the battery or a defective contact to battery ground.

Regards.

My battery light is on all time on the dash, why?


There is a fault in your battery or the alternator or voltage regulator. It is most likely the alternator as in this model the voltage regulator should be built into the alternator. You can remove the alternator and have it tested at Auto Zone or Advance auto or Pep Boys, most major auto parts stores offer to test them to make sure that is the problem. Since you would have to trade in the old one as a Core to get the new one it only makes sense to have it tested first anyway.

My 2000 Chevy Blazer battery light is on. This


Could be anything from corrosion on cables, loose cables, lose or faulty wiring of wires behind alternator
defective voltage regulator. Visually inspect all the items noted. Then use a volt meter and measure the charging voltage of the alternator. It must be between 13,5 to 14.5 volts with and without accessories on at idle and 2000rpm. Anything below 13.5 weak battery or defective alternator ,lose wiring , corrosion. Anything above the 14.5 volts is a defective regulator.

Overcharging Alternator


Very short lesson on the charging system. Remember this, The higher the voltage the less the amps.in turn low voltage, high amps. When the Alternator is charging at or above 15v, It is virtually pure voltage and as a charging device is cooking your battery, not charging it. The alternator, though defective, is safe and your battery is in harms way. When an alt. is charging at or below13 volts, The charging amperage is approaching max output of the alternater, which, if maintained at that rate will overheat and cause alt, failure, The proper charging range is 13.6 to 14.2. Each end is the limit just short of maximum and eminent failure. Example: charging at 12v means the alternarer is at max output and is in danger of sling solder, litteraly. When you smell dulphur coming from the battery, The alt. is running wide open on the voltage and your batt ison death row. So, back to your problem. One more thing. All accessories that are designed to operate on 12v are art risk of being damaged from excess voltage. Some have a voltage limiter to protect against surges but not all. Oh, That is one heck of a hot alt at 140 amps. Is that original equipment? Well, I know I may have rambled a bit but I hope it helped you understand how it works so you can come to the conclusion I have. The Alternator has a bad regulator and is in whole or part defective. Good Luck, Ned

Charging problem on 2005 Suburban - gradual voltage reduction


This vehicle has a "Regulated Voltage Control" system. The computer reduces the charge voltage based on several parameters to improve gas mileage. Normally it shouldn't be a problem, but the computer will increase the voltage if you switch on the headlights. Also, if you're in Tow/Haul mode the voltage will increase.

Voltage regulator


Voltage regulator is built-in to the alternator assembly.

Have you tried replacing the battery?
A battery with a shorted cell will not charge properly and may even damage an alternator or regulator.

Note1: use a digital voltmeter (about $25 at Lowe's or Radio Shack) and check voltage across batt terminals while engine running. If more than 12.6 Volts DC and more typically about 13 Volts, then the alternator is working.

Note2: from Jan 98 to May 98 shows a different part # alternator than June - Dec 98
check the manufacture date on your driver door edge.
