      A:

      I'd be happy to help you with that! The voltage regulator for your vehicle is built internally into the alternator. You would need to get an alternator if you need to replace the voltage regulator.

      A:

      It's inside the alternator. Almost all automotive alternators have an integrated regulator.

      A:

      You just need an accurate voltage meter.

      Connect the meter to the poles of the battery. Start the engine and avoid spinning her up, even not for a short moment. The reading of the meter now can be anything; a reading lower than 12.6 volt indicates a weak battery.

      Slowly increase the engine speed. The meter reading should increase too, but will get "catched" at an engine speed somewhere at 1000 rpm. (8001200) From then on the reading will stay "locked". It should be 13.8V; 0.5V higher or lower is the limit of what is acceptable. A voltage too high is NOT good: it will ruin your battery and wear out bulbs and other equipment!

      A voltage regulator is good when the reading hardly reacts to change of engine speed or to adding power consumers like electric window heaters or main headlights.
