Buick Century battery not charging?

Asked by Jul 31, 2016 at 04:24 PM about the 1998 Buick Century Custom

Question type: Maintenance & Repair

My battery ran down a couple times. I had it checked and it checked out good. Checked the voltage at that battery when the car was running and only read 11.2 volts. I figured bad alternator so I took it in and had it checked. Checked good. Putting out 14.2 v. Put it back in and still getting 11.2 volts with car running. I thought it has to be the alternator so I purchased a new one. Put it in and am still only getting 11.2v at battery when the motor is running. Battery reads 12.1v when car is not running. Not sure what to check now.

Does anyone have a suggestion?

Does the battery or alt light turn when you first turn on the key before you start it's? If not that needs to work as it is part of the exciter circuit for the alternator.

Alternator light does light during light test when starting car. Goes out after a couple seconds. Jim

Ok good so that half is working, the next thing is getting a live data scanner and check to see if the computer is turning on the alternators regulator system, i just hope it actually works on the new alternator.

I will give that a try. Thanks for your help on this.
