2000 Ram Van - is the voltage regulator located in the alternator
I have a 2000 Dodge Ram Van, V6. Every now and again, the volt output will drop to 0 and the check guage lite comes on, then a few munites later it's fine, the voltage is back to normal. I believe it's a problem with the voltage regulator. However, I do not have much experience with Dodges, and am not sure whether the regulator is independent or located in the alternator.
Has anyone experienced a similar problem? Does anyone know if the regulator is independant or in the alternator.

The voltage is regulated by the pcm (power control module ) on the truck. You cannot make any adjustments, removed or tampered with in any way to the pcm. Only a dodge dealer can check it out to see what the problem is with the pcm. Hope this will help you.

The way to check for an over or under charge is to connect your volt meter to the battery, before starting the vehicle.
You should have a reading of 12.5 to 13 volts. If it's 11.8 like you stated or less, it means battery is not fully charged, or it's bad. Now start the car & check voltage again while running the engine, the voltage should exceed 14+ volts, this means your Alternator is charging, the voltage should drop after battery has been charging for awhile. When you turn the engine off after letting it charge the battery, & if the battery is good, you should now have 12.5 volts to 13 volts.
Now to answer your question, the Voltage Regulator is inside of the Altenator, I believe you xcan take the alternator apart to replace it, or simpler to just replace the complete alternator.
In some brand of alternators the regulator and brushes are an integral part and it is a matter of removing 2 screws and lifting out the part. On others the regulator is entirely separate unit located some where else on the vehicle. The voltage of 15.3 is on the upper end of the charge rate but it would be acceptable . Nominal voltage for a regulator is 14.5 to 15.5 volts. Understand that a battery is actually 13.2 volts not 12 volts and you need 14 volts for the battery to charge effectively. The higher the voltage the higher the amperage to run everything so if your alternator regulator is set at 14.5 volts then the max amps of the alternator would not be reached and if you have a current draw to run everything that is more than the output of the alternator then the battery will eventually go flat. Find yourself a reputable auto electrician and discuss the problem with him not a local mechanic
the amperage of the alternator is immaterial as long as it is big enough to run the electrics of the vehicle
what is indicated here is that the new alternator required an external voltage regulator or a properly operating regulator to regulate the output voltage
battery voltage in a new battery fully charged is 13.2 volts dc and when the voltage regulator is working the controlled voltage is 14.5-14.8 volts dc
check how you wired up the alternator and have an accredited to test the charging circuit
Hello, again, again Bridget. First I sent you explanation of the ignition system
and I gave you my best guess---ignition module on your 1994 Plymouth with V6 3.4
As far as voltage regulation goes there isn't any external
devise to do this. This voltage voltage regulation take place inside the
alternator after the three phase AC voltage is turn into none regulated DC
voltage. Now this DC voltage goes thru a voltage regulator that built into the
alternator where the output DC voltage is 13.8 to 14.1 DC Volts. Now, the
alternator is regulated for current by the it wire windings in the alternator.
Larger the copper wire the more current the alternator will produce.
not like the old days it does not have an external regulator-it is integral with the alternator now, use a digital voltage meter to read the output at the rear of the alternator (large post)-is should be about 14.2 volts.
I had this problem. i thought it was a parasitic drain but...
check your charging system. with the van running, check the voltage output accross the battery terminals. if its less than 14.1 check the inline fuse for the alternator (close to the alternator) if ok, replace the voltage regulator inside the alternator.
if the charging system is putting out 14+ volts then you need to start pulling fuses while van is off while monitoring the current draw between the positive battery post and the positive terminal clamp watching for a current drop. keep in mind the windstar will drain alot of current while off for the first 2 mins er so, then it will drop again in about 15 mins... time delay shutdown on several systems :)
the voltage regulator is in the computer,check you battery with volt meter with engine off it should say 12volts then check it again with engine running and it should say 14-15 volts. if not the you will have to take it to a dealer to check the computer,hope this will help you!!!
