Is it normal for my battery voltage to be around 17 volts?
OK, -how- did you test the Alternator & battery. What's your definition of test.About a week or two.however alternator is only a year old. I checked the alternator it passed. I also checked the battery and also passed. Even tried a really old battery and the alternator brought it back to life. Maybe its just a really kick ass alternator. Our maybe my voltage gauge on the car is screwed up.
