Question about 2002 Dodge Stratus
Tested Battery with Multimeter while Idle Motor Spiked from 11.8Volt to 15.4 Volt.
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.

Justin85shad pretty well answered your question. The voltage regulator is built internally into the alternator, and the best way to replace it is by replacing the alternator. Get one at Autozone, or a similar place which carries a lifetime warranty, and is easily located anywhere you go, but first make sure your battery is fully charged and the alternator is still spiking too high. If your battery was weak when you tested the alternator, it may be working properly and not need replacing.

The voltage regulator on the stratus is located within the alternatorit is possible to replace the voltage regulator independently however is rather difficult to do so in the voltage regulator is nearly the same price as the alternator itselfyou should expect to see 14.2 volts at the battery when tested with a voltmeter while the engine is running at idle regardless of load biet headlights on headlights off heater air conditioner what have youyou can also have the entire charging system starter alternator battery tested for free at an advanced auto or autozone. good luck

Usually we start with the regulator as it is the less costly and easiest to replace of the two. Additionally replacing the stator and regular in pairs is not a bad idea...unless you happen to purchase a defective one. Sorry don't have better news.

to check if the charging system is charging you also need an amp meter hook that inbetween the battery lead on the pos + side of the battery and with the engine running turn on all lights if the amp meter reads - charge its not charging the batery up,,change the reg first,, thats the chepest part,,,the charge will only just be above what you need with all lights on eg 1.5 - 2 amps
