alternator signs

[sick1166]

2007 150,000 does alternator show signs before dying?
does it just die?
how many miles does one get on a oem alt

In my experience, they just die with no warning.

09 Tahoe, Does anyone else notice that on the gauge that it goes from 14+ to the line in between 9 and back occasionally? Or is mine defective?

mine lately seems to go from 9 - 16 most times around 14 but moves a lot lately between 9-16 thats why i asked maybe goig bad? but no problems and its been a few months now

It may start making a whining sound.

In my 99 burb it would stay consistent at 13, it didn't fluctuate like the 09 hoe does. It had me curious too sick1166.
