I recently changed my truck's alternator and battery coz while driving I was getting voltage readings in this range: 12.3-13.5. I was also hearing an unsettling noise coming from under the hood when voltage dropped down to 12.5 or below, and as I read up on bad alternator symptoms, that type of noise was mentioned as one symptom. After replacing alternator and battery, I'm now getting voltage readings as high as 14.2 and mostly in the high 13s, but I've experienced readings as low as 13.4 as well. My question is: why am I getting occasional low voltage, 13.4? Is this normal and what is the normal range?
