Default 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?

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

New doesn't always mean good.

Regards,

David

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.

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