06 Avalanche Problems Hi Everyone,
I'm new here and am looking for some help. I have an 06 Avalanche that has been having some issues. Had to replace a battery about 6 weeks ago. Ever since, been having some issues. Alternator was really dropping voltage and charging right at, or below 12 volts, to as low as 10.5. Replaced and worked great, for about a day. Now, it will be reading great when I go to have alternator tested, but as soon as I pull out and start driving, the voltage drops. I had a bad tensioner, replaced it, replaced belts, checked, cleaned and re-secured all ground connections. But my voltage is still charging at or less than 12 volts running down the road. ANY IDEAS-PLEASE HELP. Had a "system charging failure" message pop up in the DIC the other day. Could it be I got a bad alternator?

alternators need voltage to make charging voltage. i would test the connector that goes into the alternator to make sure its getting the correct voltage. if its not, then it wont charge for anything. after that just make sure all positive wires in that charging system are good. and check batter if it has a weak or dead cell that can change it over 2v.
goodluck
