can a voltage regulator on a 2005 saturn ion be replaced w/o the alternator being replaced? I have mechanic that has had my car for months, he has since put an engine in it, replaced sensors, told me it needs a new battery, We originally got the car back from him in jan for a few days after 2 months of taking the car because the first engine was no good. We buy the battery, and now he said it's not that, it's the voltage regulator.
