2003 Suburban voltage problem

I have a new battery and alternator.
The voltage still reads low on the gauge and at the battery!
What is the cause?
What is robbing the voltage?

RE: 2003 Suburban voltage problem

Are you sure the voltaage is low? What's the voltage at the alternator and the battery?

New doesn't always mean good.

New alternater or rebuilt alternater ?
There is a big difference between the two... you can't trust the rebuilds.

What are the volts that you are getting? Could also be something as simple as a bad ground or corrosion or a broken wire.

RE: 2003 Suburban voltage problem

have you cleaned and tightened the power and ground cables, including the mounting bracket for the alternator?
