Question Volt gauge reads constant 15... That okay?

I'm just a postin' fool, today.

I'm not overly concerned, just curious: my volt gauge is reading a constant 15, rather than what I'd assume should be a normal 14.
Does that for the first few minutes at least, not sure if it does it all the time...
guess I haven't paid that much attention.

Is that okay?

Not right. The voltage should not go above 14.2v no matter what. At anything higher than that, you ECU will start flipping. Check you alternator. Its voltage regulator is probably AFU.

When I first start my car up during a cold morning or night it always reads really really close to 15v. Then after it warms up it drops down to a dead on 14v. After it's warm it stays at a steady 14 unless I have a bunch of accessories running then of course it drops. But WOT or idle is 14v.

It could be that your voltimeter is wrong too. I have a digital voltimeter (from Whistler which I got for $6 and hard-wired it to the cigarette lighter wire). I checked with a multimeter also, and my voltimeter almost checks with the multimeter. I get somewhere between 13v - 14.9v.

Well I guess there's no cause for alarm, then. I may bring it up to the dealer on Thursday, but no worries.

It's only a 5-10 minute drive home, but after work, I let my car warm up for about two minutes, then made the drive (2/3 highway, I'd say). By the time I got to my garage, the volts were down to about 14 (stereo on or off).
