Yes but the problem might be misdiagnosed. Keep in mind if you read your manuals, that the generator puts out 50 volts, and the regulator reduces it to 13.4-14.4 Several electricians have speculated that the problem is a bad stator. Why would it be the regulator, since that is a problem usually indicated if the voltage is too high?

2nd newly rebuilt alternator burning out.


Due to the nature of the battery technology used with vehicles the alternator is mostly incapable of charging the battery. The car alternator is designed to keep a fully charged battery fully charged and to provide all the power for the car equipment.

The alternator charge rate is regulated by a voltage regulator. Because the alternator output is connected to the battery, the alternator and battery voltage will be the same and the voltage regulator monitors that voltage.

The lower the battery voltage the more output the alternator will produce in order to correct the situation but because a lead acid battery has a high internal resistance to accepting a charge the terminal voltage will quickly rise to the alternator regulated voltage and fool the alternator into thinking the battery is fully charged when the output will drop to the order of just a couple of amps.

Switch on the headlights or a similar load that will lower the battery voltage and the alternator will increase it's output again - but only by the amount of current the headlamps or other load is consuming.
It matters not what the alternator rated maximum output is, it is designed to provide only the necessary current and no more.

The only time an alternator should ever need to produce maximum output is when on a dedicated testbed and then only for a short duration to avoid damaging the unit. Testing the current output on a modern vehicle is not recommended except for the regulated voltage testing and a rule-of-thumb output test where all equipment is switched on and the engine speed raised while the battery voltage is monitored.

Most modern alternators use an internal voltage regulator but a few systems use a separate voltage regulator. No alternator rebuild would be complete without a regulator test and probably a new or replacement regulator, which is where the majority of charging system problems are, or the brush gear.
Assuming the wiring is ok, no alternator should suffer any harm if the voltage regulator and auxilliary diodes (if fitted) are in good order though fitting a defective or a discharged battery can cause it to overheat and be damaged.

The alternator usually just about stops producing an output when the battery voltage is in the region of 14.5/14.8 volts.
Your description indicates the voltage regulator is not working correctly - unless 40 amps was being consumed by the car equipment the alternator should not have been producing 40 amps.. I suggest you also have your battery tested

depends on the state of the battery , The regulator looks at the battery charged state and regulates the voltage to fully charge it , If the voltage does not drop back after a few hours the battery could be on the way out.

NOT CHARGING CORRECTLY. NEW ALT, BATTERY. CODE SAYING VOLTAGE REGULATOR. THEIR IS NONE, IT'S PART OF THE PCM FROM I'M READING IN THE HAYNES MANUAL


You are misunderstanding the manual. There is a voltage regulator and it is part of the engine computer. When the regulator goes bad, you need to replace the computer. Its a really bad design but that's the way it is!!! There is a "work around" involving bypassing the computer and installing an external regulator but it turns the light on and won't pass inspection that way.

New alternator new battery installed still wont charge the battery and radio and power anttena dont work


If you have a voltage meter, you should check if your voltage regulator is working correctly. The voltage regulator should keep the voltage to the battery something under 15 volts when the motor is running (more than 13.5 volts with all electrical turned off).

If more than 14.5 volts, you may be damaging your new battery and regulator is not working properly. Also, radio may not come on because a voltage sensor is protecting it from the high voltage. Antenna is controlled by radio so that should not be working either.

Good luck.

1982 Yamaha XJ 550, the battery will not take a charge. New battery, checked all connections, ran all the tests (stator, brushes, and alternator). Replaced the voltage regulator/recifier. Not sure what is...


It is corrected properly, right? + to the wiring harness and - to ground ... right? Are you certain about the rectifier? Is the battery charged at this time?

You know a alternator cannot make power unless you first put power into it ... right? Alternators (unlike most generators) are not self exciting. If your battery is weak or "dead", the alternator cannot make electricity to charge the battery. I don't know what the rating of your alternator is. Your battery should be fully charged before you do any more tests. If you have a 1 amp charger, allow at least 10 hours for a full charge. Don't cook your battery with a big, powerful, fast charging automotive battery charger.

Good luck with your repair ... I hope you find this response helpful.

Thanks for your question @ FixYa.com

Battery will not charge, first time its ever did this. rebuilt alternator new battery and new starter not to sure if new starter has anything to do with battery chargin but replaced it anyway, has good...


A bad voltage regulator could cause the problem. Assuming the alternator is working correctly. Jump the vehicle with the battery disconnected and then disconnect the jumper cables. If the vehicle dies your voltage regulator or Alternator are bad, some vehicle have separate regulators from the alternator, if it continues to run the alternator is good but the voltage regulator is probably the cause.

Batteries won't charge


Hi. Sounds like there is a faulty connection somewhere between the charger and the batteries. Are the batteries connected correctly. The charger uses the voltage level in the batteries to regulate itself. If there is a faulty connection, then the charge will not operate. Use a multi-meter to check if the batteries are connected correctly. There should be 24 to 26 volts across both batteries.
This fault can also be caused by a faulty charger socket. Check for any signs of melting or heat damage. There might also be a disconnected wire in the plug on the charger itself.Good luck. Neil.

My bike charges the batteri badly. It doesn´t matter if the bike is running or if it´s on standing still. If i turn on the lights when running the charging is even worse


first of all check the voltage across the battery with the bike running,it should be between 13.2 and 14.5 volts,if it is not then there is a good chance that either your alternator or generaator need new brushes or by your description hane the voltage regulator checked or replaced,if this is not working correctly you will not charge the baateery,hope this helps

My battery is good but not getting charged on my buell


Check your conections at the batery and at the selonoid. It could also be your voltage regulator or the generator, the repair manual should tell you how to test them.
