★ Top Answer
The voltage regulator in a 2000 Mazda Protege is located in the alternator. As of the 2002 model year, the ECU in the Protege started to handle this function. If you need to fix or change yours, don't worry, it's not too costly. The challenging part is gaining proper access to the repair area, which calls for some knowledge and confidence in automotive work. You can usually get a new voltage regulator for your car for about $150, or up to $200 for a higher-end brand. While it's not a super expensive replacement, it's not pocket change either, so it's advisable to test your component with a digital multimeter first to make sure you actually need to replace it before spending your hard-earned money.
