I have just discovered this site and am looking forward to learning a lot from the folks on it. I have a red 1979 Mazda RX-7 with only 78K miles on it, and it has run well all this time. However, when I recently had the alternator replaced, the Engine light came on, and my mechanic says it needs a new voltage regulator. After I have posted 3 initial posts, I am hoping someone can help me locate a replacement regulator. Thanks.
