batt voltage numbers - running (Edge CTS)
So I have been getting FICM voltage warnings on my Edge. While looking into that issue, i noticed that it also listed volts as 12.4 at idle. I have been watching the batt v and it ranges from 12.4 to 12.8, idle to running at highway speed.
Questions is: most cars I have owned run at about 14v from the laternator, and that is what is recorded at the volt gauge. If the Edge is picking this up direct off the batt, maybe it makes sense, but it still looks awful low to me.
Makes me wonder if I really have an alternator problem, and nothing is wrong with the FICM except it is not getting enough juice.
So what are your volatge numbers?
