Angry help with check engin light and traction control

My daughters 2006 HHR quit on the side of the road, hubby thought it was battery, went and got new one and the check engine light was still on and lights were dim so we knew it was probably alternator. So took it to the shop and they put a new one in. I know it was new because i bought it from parts store myself. So went to pick it up and the check engin light and traction control light was still on. They got them to go off, took it off the racks, she got in it cracked it and light still on. I had to end up leaving it with them again for the 4th night! I called and they said they are going to look into it someone but think it could be in the computer. The lights were not on before having problems with the alternator. Can someone give me some insight on what it may be or what they could do to find out what iti is. They put it on the cod thing and I guess that didnt work ! HELP!!!!!!!!!! .

Welcome to the site!
Did they read the codes from the CEL?
Did they disconnect the battery when the changed the alternator?
Did they install the alt drive belt?
Stranger things have happened!
Did they load test the battery?
If they will give you the codes post them here for us to advise you.

Can't really give an opinion without the Check engine light code numbers.

OK. One thing that caught my eye in your post: " thought it was battery, went and got new one and the check engine light was still on and lights were dim"
A new battery and lights were dim sounds more like a ground wire problem.

So to clarify ,
New battery
New alternator
Still the battery light is on?
Double check the ground wires make sure they are clean and tight, there are grounds under the hood and in the spare tire well!

Without the codes and the voltage output(static and engine running) it's impossible to offer any help.

Codes

So this is what the ship told me. They drive it this morning, light was off. Let it sit awhile, drive again it comes back on. Done this a few times in and off goes the light. They said B1325 code shows up in body control module and radio. Also some other codes that showed was P0102,P0113, P0300, P0622 and B3006. Please need input! I don't want to keep putting money into this if it is not worth it!

Last edited by whopper; Oct 30, 2015 at 12:00 AM. Reason: edited the posted codes - ie: it is P0102, NOT PO102 - only the first character is a letter, the rest are Numbers - big diff.

OK, those codes are a real hodgepodge, gonna have to pull up my FSM and read through some fault trees.

In the meantime folks, chip in with your insights.

These Trucklets are complex electronically lilmoe, so an immediate answer might not be possible, but we'll come up with some ideas.

Body Control and Powertrain Codes suggest a "Cascade Failure" where one is the root cause, and the rest are like toppling dominoes.
