Voltmeter Readings?

[czylka]

I have a '99 Tahoe, and was wondering if it is normal for the voltmeter on dash to read high volts (15-16) upon starting in cold weather, then drop a bit to 14 when the engine warms up? Is this an indication of a weak battery? Alternator problem? Loose belt?

Thanks a ton, I've learned a lot from these forums!

Colin: Normal voltage output to the battery is between 14.2-14.7 volts. Cold weather really puts a drain on the battery. I think you're just fine. Of course now that I've said that, The alt or batt will probably go "belly up". Serpentine belts, to my knowledge, don't get loose they just break.......Steve
