Is the voltmeter reading on my truck still high?
Started the truck and the reading on the gauge is now on the 14 side of about halfway to the dash. So I took the truck for a little drive. Gauge is still reading on the 14+ side. Better but I’ll have to keep my eye on it. I’ll drive it around some more and see if it continues to stay high or act normal.
What should the voltmeter reading be on a new battery?
Nope…a good new battery should read 14.2-15V…anything over 15 is bad..but if your relying on your dash gauge to give an accurate reading….thats not a great idea. your lucky if it’s accuracy in within 10%… Your fine. Thanks for the replies guys. I guess I’m more concerned with why my voltmeter in the dash is reading so high now.
What’s the voltmeter reading on my GMT900?
I drove it last weekend and noticed that the voltmeter is reading between 14 and the next line (16?). I know that with the GMT900s, the reading will fluctuate. So I drove around a bunch, but the reading stayed above 14. Next day, I drove around some more, with the engine running for over an hour or two, and the reading was still above 14.
