What does your volt gauge read?

[bkboatnsleds]

Maybe Im nuts - but does not seem to high?

I have a bad bearing of some sort going out under the hood - I can hear it, not sure what it is yet but I have heard when a Alt. goes bad thy can over charge -
What does your gauge read??

What is the temperature outside?

Mine usually reads 14.7-14.8(one dash above 14v) sometimes a little higher when I start it in the morning. I'd have the alt tested just to be safe.

Mine usually runs a small notch past 14!

Mine looks exactly like yours (02 yukon 4wd) but when I use my VOM it's @ 14.0 volts with engine running, 12.2 with engine off. I don't think the on board voltmeter is well calibrated.

Mine is just over 14 as well, unless I'm really playing some shit loud as hell...I need a bigger alternator at some point but the lights don't really dim much.

Mike,
Just went outside and fired up the truck so I could verify for you.

Mine is about the same as Chauncey's and Chris', ONE (1) dash/notch higher/above 14.

1 tick above 14V all the time (til i get my subs). I have heard the gauge can be off by quite a few volts. Dont bother testing the alternator yet. Put a volt meter across the battery terminals while the engine is running. compare that to the gauge to find you gauge error. hope for 14.7 on the meter, if you get much more then test the alternator. It could have a bad regulator and you want to get it fixed before it fries something.

14

Mines reads 14.8 when started cold, then settles to 14.1 after it's slightly warmed up.
I know it's right because I have a voltage stabilizer w/a digital voltage readout on it mounted on the battery.
