Hi guys,I'm Janssen and I've got an 2008 Avenger.
A few weeks ago battery light came on and charge light came on too
i replaced battery and then installed reman alternator and it still wasn't charging
meter showed alt putting out 9 volts. I removed alternator thinking it was no good
installed another one,still wasn't charging. I had a friend (30 year tech) tell me
was most likely pcm. I just installed one I ordered from car computer exchange co
and installed a new battery too. charging light is off but battery light is still on.
anyone have any ideas?

Check and clean all connections from alternator to the battery. You may have to meter the wires too to make sure none have aged too much and provide too much resistance

Edit: Welcome to the forums, sorry we have to meet under these circumstances

Be careful with aftermarket alternators, I've had many that were defective out of the box. Granted this was on a Durango and luckily the alternator is on top of the engine(easy access). Autozone argued with me that I had 5 defective alternators and they tested them when I limped the vehicle to them and sure enough the alternators tested bad.....all 5 of them.
I installed a Mopar Reman on my car a few years ago and it was only $165 and I haven't had a problem with it since. Napa reman alternators are good, but for the price I just went with a Mopar reman replacement.
Also as "schurick" mentioned, make sure all connections are clean and tight. Since the battery is fender well mounted its always good to make sure everything is clean and protected with an anticorrosion pad or coating. It's not like you want to really dig in there all the time to keep figuring this out. Also I HIGHLY recommend a good battery to be installed instead of getting the cheapest you can purchase because again, how many times do you really want to dig into the fender well.
For a battery I was using an Optima Red Top and it failed within 1 year, the replacement lasted me less than 6months. So I used the credit from the warranty on the Optima and purchased a Odyssey(75-86-705) battery and it's been working perfectly. Of course there are other options for a battery which would be lighter also but since November 2022 and with the cold temperatures of western New York, this battery hasn't given me one issue yet.

I have had good luck with Duracell batteries, good old fashioned sealed lead acid, nothing fancy
